One of the engines was going to be his primary engine in the Toyota Owners 400 at Richmond International Raceway. The other two were his primary and backup engines for the Aaron’s 499 at Talladega Superspeedway.

David Wilson, of TRD, said:

We took every connecting rod in our inventory and removed anything that was too close for comfort.

The review revealed that one connecting rod in each of the three recalled engines was too close to NASCAR thresholds for comfort.

According to reports, the connecting rod in Kenseth’s race-winning Toyota was outside of the tolerances the manufacturer allows on weight before it was shipped. TRD employees missed it, despite the fact that the connecting rod came with paperwork that clearly stated its weight.

Harvick beat Clint Bowyer to the finish line by .343 seconds to win his first NASCAR Sprint Cup Series race of the season, his second at Richmond and the 20th of his career.

Joey Logano ran third, Juan Pablo Montoya came home fourth after leading until the final caution, and Jeff Burton finished fifth after staying out on old tires for the final two-lap run that took the event six laps beyond its posted distance.

Harvick came to pit road for tires on Lap 396, after Brian Vickers’ slapped the Turn 3 wall to cause the 11th caution of the race. Harvick’s No. 29 Richard Childress racing Chevrolet made short work of three drivers who had stayed out after the race restarted on lap 405.

Though he lost the chance to break a 94-race drought since his Cup victory at Watkins Glen in August 2010, Montoya was elated just to get a top-five finish after struggling mightily for more than a year.

Not so elated were Kurt Busch and Tony Stewart, who repeatedly swapped shots with their Chevys on the cool-down lap. Stewart was fifth on the final restart but dropped to 18th at the finish after Busch rubbed him out of the racing groove during a two-lap free-for-all that saw prolific contact throughout the field.

Harvick, however was all smiles when he climbed out of his car in Victory Lane.

“My car launched, and I was able to drive it in the first corner and hope for the best down there,” said Harvick, who surged into the lead through Turns 3 and 4 after establishing his position in the first corner on the final restart. “I figured four, eight, 12…how many ever tires that were on the outside of me would be better than none. It all worked out, and here we are.”

The decision to come to pit road for tires under the final caution was a no-brainer, as Harvick and crew chief Gil Martin saw it.

“When the tires fall off almost two seconds, you’ve got to come in and get tires,” he said. “There’s not very many guys that stayed out. It all worked out tonight. We’ve been on the other side of it this year, so to be in Victory Lane is great.”

Bowyer led 113 laps but didn’t have a car that could stay with Harvick at the end.

“We had a good car—we just didn’t have a great car,” Bowyer said. “It seemed like we were just too tight on the throttle. It would quite turn and come up off (the corner). It really got wild there at the end. I was just lucky enough to be on the bottom (for the final restart).

“They started making holes up there in front of me, and the seas parted, and I just followed suit behind Harvick. It was a good run.”

What remained a two-man battle for more than half the race evolved into an unpredictable nexus of varying strategy and unexpected attrition.

When Kyle Busch passed Matt Kenseth for the top spot on Lap 254, that was the first time all evening that a driver other than Kenseth or Bowyer had led a lap. Busch made it stick, leading 39 straight laps under green until Travis Kvapil smacked the wall on Lap 292 to cause the sixth caution of the night.

But brother Kurt Busch won the race off pit road under the yellow and led the field to a restart on Lap 299. Busch held the point during an intense battle against Carl Edwards until NASCAR called the seventh caution on Lap 308 when Kvapil’s car dropped fluid on the track.

Kurt Busch, Carl Edwards, Kenseth and Ryan Newman stayed out under the yellow on 16-lap-old tires. Jimmie Johnson paced the rest of the lead-lap cars to pit road and took two tires. Six laps after a restart on Lap 321, the entire tenor of the race changed dramatically.

After contact with Martin Truex Jr.’s Toyota on the restart, Johnson faded on the restart. Running to the inside of Johnson on entering Turn 1 on Lap 327, Tony Stewart slid sideways into Johnson’s Chevrolet. As Johnson slid to the inside of the track in Turn 2, Kyle Busch’s Toyota nosed into him.

That was just the start of frenetic action at the .75-mile high-speed short track. Montoya led a pack of six cars who stayed out under the caution to a restart on Lap 334, but on Lap 338, a brutal wreck off Turn 2 involving Mark Martin, Kasey Kahne and Brian Vickers slowed the field again.

One lap after a restart on Lap 344, Truex spun in Turn 3 while battling Kurt Busch in close quarters for the second position. Montoya retained the lead until Brian Vickers’ wreck on Lap 395 set up the overtime.

Notes: Despite Johnson’s troubles, the five-time champion gained ground on his closest pursuers in the standings with a 12th-place finish at RIR. He now leads second-place Carl Edwards (sixth Saturday) by 43 points and Kahne and Dale Earnhardt Jr. (10th at Richmond) by 46… Reigning Cup champion Brad Keselowski finished 33rd on the bottom end of a roller-coaster day that saw him recover from a scrape with the turn 2 wall only to drop a cylinder in the late going.

If you looked at statistics alone, you’d say that Kenseth dominated Sunday at Kansas Speedway in the eighth NASCAR Sprint Cup Series race of the season. After all, Kenseth won the event from the pole and led 163 of the 267 laps.

In reality, Kenseth prevailed in a race of extraordinary strategic complexity, with divergent approaches shuffling and reshuffling the running order until an opportune caution on Lap 218 put Kenseth back in the lead at just the right time.

Nonetheless, it took all of Kenseth’s consummate skill to hold off fast-closing Kasey Kahne, who narrowed what had been a lead of more than one second to .151 seconds at the finish. Jimmie Johnson ran third, followed by Martin Truex Jr. and Clint Bowyer.

The victory was Kenseth’s second at Kansas, his second of the season and the 26th of his career. The driver of the No. 20 Toyota has won both races at Kansas since the track was repaved last year.

“It was kind of like musical chairs,” Kenseth said. “You had to be out front when the music stopped. Our car was very fast in clean air. It was reasonable in dirty air, but it wasn’t quite good enough to catch all them guys and pass ‘em (in traffic).

“Thankfully, I had a couple of really crazy-good restarts for some reason and made up some ground and got us back in position.”

Kahne started 27th, but the speed in his No. 5 Chevrolet SS belied the qualifying effort. Kahne’s crew tightened up the handling of his car for the final run, but not quite enough. There was a sense of déjà vu for Kahne, who chased Kenseth to the finish line March 10 at Las Vegas.

“We were very close at the end, battling with Matt,” Kahne said. “Felt like Vegas all over again, just kind of felt like really similar to that in how I could catch him but couldn’t really do anything once I got close. It made my car a little bit looser. So I tried a few things there, and he kind of blocked those spots and went those directions and gained the speed that I (had), and then we were even again.

“It was tough, but we still had a great race.”

Defending Cup champion Brad Keselowski came home sixth, despite sustaining heavy damage to his rear bumper when the field checked up on the first lap.

That damage had far-reaching effects — so much so that it changed the complexion of the race on Lap 218. The rear bumper cover from Keselowski’s No. 2 Ford dislodged, causing the eighth caution — right after Ricky Stenhouse Jr., Dale Earnhardt Jr., Carl Edwards and Greg Biffle had made green-flag pit stops.

But since all lead-lap cars came to pit road under the yellow, those four drivers were able to regain the lead lap through wave-arounds. Kenseth led the field to the restart on Lap 225, with Truex beside him and Hendrick teammates Johnson and Kahne on the second row.

Kenseth pulled away after the restart, and Kahne charged into the second spot. On Lap 236, Johnson passed Truex for the third position. That’s the order in which they ran to the finish.

With his third-place finish, Johnson opened a 37-point lead in the Cup standings over second-place Kahne, who gained five spots. Johnson is 38 points ahead of Keselowski in third.

Keselowski position in the standings reflects a 25-point penalty levied after the Apr. 13 race at Texas, where NASCAR confiscated the rear axle housings of both Penske Racing cars and subsequently levied penalties on the organization. Penske has appealed, but Keselowski won’t regain the 25 points unless the appeal is upheld.

Note: For the third straight race, a driver won from the pole. The last time that happened was 1985 (Bill Elliott at Michigan, Dale Earnhardt at Bristol and Elliott at Darlington).

Leading 346 of 500 laps in Sunday’s STP Gas Booster 500 at Martinsville Speedway, Johnson racked up his eighth NASCAR Sprint Cup Series win at the .526-mile short track and the 62nd win of his career. For the second straight event at Martinsville, Johnson won from the pole.

Clint Bowyer ran second, followed by Jeff Gordon, Kasey Kahne and Kyle Busch.

The first repeat winner through six 2013 Cup races, Johnson regained the series lead by six points over sixth-place finisher and defending champion Brad Keselowski.

If a victory at a short track can ever be called a walk in the park, Johnson enjoyed a Sunday stroll from start to finish. At no point in the race did he run below fifth.

“I think the fact that we had just such a calm weekend was the biggest part,” Johnson said. “It’s easy to start chasing things here and get yourself off track. We always race well, and fortunately here you pit a lot and you can make big changes to your race car to get you in the ballgame.

“We’ve won races where we were just terrible to start the race, having no fun. (Crew chief) Chad (Knaus) is throwing spring rubbers in the car and the track bar is coming up or down, wedge in and out, all those huge, huge changes, and we get ourselves in contention.

“I don’t know where we were – someone said the worst I was on the track today was fourth [actually, fifth]. We just executed from the first laps in practice to where we were at the end of the race, and that was fun. We weren’t chasing a setup or track conditions or a variety of things that we’ve done in the past.”

Danica Patrick ran 12th in her first visit to Martinsville, her career-best Cup finish at an open-motor race track. Patrick was the top finisher from Stewart-Haas Racing.

NASCAR red-flagged the race on Lap 487, after the brakes failed on Kurt Busch’s No. 78 Chevrolet SS and sent the car hard into the Turn 1 wall. The car rolled along the fence, spewing flames from beneath the hood.

Busch had the presence of mind to trigger his fire extinguisher before the exited the car and climbed from the driver’s-side window apparently none the worse for the flames.

After the stoppage, Johnson led the field to a restart on Lap 493 with Bowyer beside him in the outside lane. But Johnson pulled away over the final eight laps to beat Bowyer to the finish line by .628 seconds.

To say that Hendrick Motorsports in general and Johnson in particular have a handle on Martinsville is a massive understatement. Johnson gave owner Rick Hendrick his 20th Martinsville victory, breaking a tie with Petty Enterprises for most ever at the paper-clip shaped speedway.

“There’s just certain tracks where the drivers that Hendrick has had over the past, as well as now—and just our race cars—it just really suits that,” said Gordon, who had a strong car on long runs but couldn’t keep up with his teammate over the short haul. “Qualifying up front really can be huge here.

You get a driver like Jimmie and a team like the 48—or ours as well, or the 15 (Bowyer)—you put them on the pole in that No. 1 pit stall (closest to the exit from pit road), and it’s going to be really, really hard to beat them.”

Bowyer’s winning chances suffered a blow during an 11-car incident on Lap 180. As caution flew for a crash on the backstretch, Bowyer ran into Jamie McMurray’s Chevrolet, which had checked up suddenly off Turn 4, and was clobbered from behind by his Michael Waltrip Racing teammate, Martin Truex Jr.

Bowyer had been strong in practice but qualified 15th and felt the mediocre performance in time trials had hurt him.

“I qualified bad, got ourselves back there, got it wrecked—got it tore up on both ends,” Bowyer said. “You get up there, and you’re door-to-door with the 48 that’s been enjoying clean sailing all day long, you look at him, and it’s ready to go back to the next short track.

“Mine is all tore to hell and ready to go put a new body on it. You know what you’re up against. You want to say, ‘Bad luck,’ and everything  else, but you make a lot of your own luck. We did a lot of things well this week but missed it in qualifying and ultimately paid the price.”

Patrick, who started the race at the rear of the field because of an engine change, restarted 20th from the outside lane on Lap 369 and promptly dropped five spots as cars in the inside lane freight-trained her.

But Patrick patiently and methodically drove back to the 17th position and was running there when Brian Vickers cut a tire and spun on Lap 448 to cause the 10th caution of the afternoon.

The yellow gave drivers a much-needed opportunity to pit for new tires. Out first after the stops, Johnson led the field to green on Lap 459 with Gordon beside him. Yellow flew again shortly when chain-reaction contact between Vickers, Patrick and Dale Earnhardt Jr. sent Earnhardt spinning in Turn 4.

Johnson passed Earnhardt as the driver of the No. 88 Chevrolet tried to re-fire and right his car, putting Earnhardt a lap down. Earnhardt finished 24th and fell from first to third in points, 12 behind Johnson, his Hendrick Motorsports teammate.

Notes: The 346 laps led are the most for Johnson in a single race in his career. Johnson also became the seventh driver in Cup history to lead 2,000 or more career laps at Martinsville. His total now stands at 2,327. … Despite fighting the handling of his No. 11 Toyota for much of the afternoon — and despite a snafu on pit road when he left before his left-front tire was mounted – Mark Martin salvaged a 10th-place finish subbing for injured Denny Hamlin.

“This is one of those tracks that, as a driver, you feel like you really need to win at,” said Kahne, who snagged the lead on a final restart with 40 laps left and held off both Kyle Busch and Keselowski in Sunday’s Food City 500.

“We’ve been trying for a long time. To pull it off, I feel is a big accomplishment for our guys and myself. There are so many things that are thrown at you when you come to this place. We’d been fast here other times and not able to finish the deal.”

Kahne, now seventh in the points standings, had finished no better than fifth in any of his previous 10 Cup races at Bristol.

The final restart came after Kahne’s Hendrick Motorsports teammate Jimmie Johnson blew a tire, bringing out the race’s 10th caution.

Prior to the final green-flag run, Kahne and Keselowski had staged a furious short-track duel that rekindled memories of the door-to-door racing that made Bristol famous.

“I’m (thinking) how can I get by and he’s (thinking) how can I hold this guy off,” Kahne said. “I reeled him in, but he was driving into the corners so hard, I really couldn’t do anything on the bottom. I bumped him a few times. He was sideways a few times trying to hold us back.

“I felt like we got a really good restart, got the lead and, from there, it was just momentum and trying to drive away.”

Keselowski knew he was in trouble after spinning wheels on the final restart and watching Kahne set sail.

“I don’t think I had anything for Kasey. I don’t know if anyone did,” said Keselowski, the defending race champion who finished third. “He was so good through the middle, really everywhere. He was kind of in a league of his own.”

Kahne credited his team, led by crew chief Kenny Francis.

“It’s fun to come to pit road and break even or gain spots,” he said. “The guys have just been nailing it on pit road.”

Not everyone made up ground in the pits.

Busch, who won the pole in track record time on Friday, posted the fastest laps in both of Saturday’s practice sessions and then won Saturday’s NASCAR Nationwide Series event, led the first 55 laps before a pit-road speeding violation under caution shuffled him back to 32nd. He was undaunted in his recovery, clawing his way back to 16th in the next 40 laps and moving to second behind teammate Denny Hamlin on Lap 155 after the race’s fourth caution.

“We battled back. I wish I could have kept up with the 5 (Kahne), but he took off and left us all,” Busch said.

Hamlin led 117 of the first 189 laps before surrendering the lead in the pits to teammate Matt Kenseth, who suffered his own misfortune when race leader Jeff Gordon blew a right front tire on Lap 391. Gordon climbed the track with his tire going down and Kenseth had nowhere to go, slamming into the rear of Gordon.

“Not a lot either one of us could do about that,” said Kenseth, resigned to a 35th-place finish.

Joey Logano, who started 10th, had been making steady progress and was challenging Gordon for the lead on Lap 348 when he tangled with Hamlin, his former JGR teammate. That led to a post-race exchange between Logano, Hamlin and team members.

Asked if he and Hamlin had a problem, Logano replied: “If we didn’t, we do now.”

Keselowski’s third-place finish vaulted him to the lead in the Sprint Cup point standings, nine points ahead of Dale Earnhardt Jr., who finished sixth after qualifying 32nd.

Johnson, who entered as the points leader, finished 22nd after running in the top 10 most of the day and fell to third in the standings. Kurt Busch finished fourth, his best showing for Furniture Row Racing, and Clint Bowyer was fifth.

Gordon crossed the finish line 1.028 seconds ahead of Clint Bowyer, his nemesis from a week ago at Phoenix, as Johnson’s No. 48 Chevrolet sat forlorn in the garage, Johnson’s title hopes the victim of a pit road mistake and a rare part failure.

Ryan Newman ran third, followed by Kyle Busch and Greg Biffle.

Keselowski finished 15th, a lap down, but Johnson’s difficulties took the suspense out of the title fight in the closing laps of the race. Johnson entered the season finale 20 points behind Keselowski, but his 36th-place result cost him second place in the final standings.

The Cup championship was the first for team owner Roger Penske, and the first since 1975 for car maker Dodge, which is leaving Cup racing at the end of the season.

“It means the world — it really does,” Keselowski said. “I’ve got the best team in racing, and I’m just so thrilled to be a part of it. From the top down, Roger Penske, (crew chief) Paul Wolfe, everybody else, the crew guys and my family — that means so much.”"

Bowyer passed Johnson for the second spot in the standings, 39 points behind the first-time champion. Johnson held third, 40 points back; in 11 full seasons of Cup racing, Johnson never has finished lower than sixth.

Gordon made some history of his own. He won for the second time this year and the 87th time in his career, most among active drivers and third-most all-time behind Richard Petty (200) and David Pearson (105). The victory was Gordon’s first at Homestead and the first for Hendrick Motorsports.

“This is just huge,” said Gordon, who wrecked Bowyer in retaliation last Sunday at Phoenix and drew a $100,000 fine and 25-point penalty for his actions. “Man, it’s been an emotional week and a hard one — one of the hardest ones I’ve ever gone through, just looking back on my decision.

“What an unbelievable week. There were so many ups and downs this week, and to be able to end in Victory Lane with just an awesome team effort was just awesome… This is the way you want to win a race, by just going to battle with them and having a good race car and playing it all out really smart.”

Aggressive pit strategy put Johnson in position to challenge for the title, but the race fell apart for the 48 team after the 200-lap mark.

Able to finish the race on one pit stop to Keselowski’s two, Johnson brought the No. 48 Chevrolet to pit road on Lap 214. Johnson, however, pulled away from his stall with a loose lug nut, and NASCAR mandated another stop to correct the error.

The coup de grace came on Lap 224, when Johnson returned to pit road with the drive line problem. The No. 48 crew pushed the car to the garage, where it sat for the rest of the race.

“Yeah, we were in position and putting the pressure on the 2 car (Keselowski) like we needed to,” Johnson said ruefully. “I said at the beginning of the week, 15th isn’t a lay-up, and I certainly had him in position.

“He made it really interesting here at the end of this thing. If we could have not had the mistake on pit road and then the gear failure at the end… Didn’t really catch exactly what happened, but I know there was oil under the back of the car.”

Keselowski, who didn’t cover Johnson’s move when the No. 48 topped off the fuel tank on Lap 158, knew he had dodged a bullet.

“He was going to win this race, and I know that,” Keselowski said. “We were not as fast as we wanted to be, and we’d be the first to admit that, but my guys never gave up. We kept working, and at the end there we were even capable of getting back up enough to where it wouldn’t have mattered if he’d have won — which made me feel a lot better.”

Notes: Pole winner Joey Logano started from the rear in a back-up car after a crash in practice and finished 14th in his last race for Joe Gibbs Racing… Matt Kenseth ran 18th in his last ride at Roush Fenway Racing… Tony Stewart finished 17th in the 500th Cup start of his career.

On lap 312, as Bowyer went to pass Gordon on the inside, Gordon retaliated, turning Bowyer. Gordon and Bowyer collected Joey Logano, who was outside of Gordon, and all three cars hit the wall. All three cars suffered heavy damage. Aric Almirola spun behind them and slid into Joey Logano’s already-damaged race car.

After Gordon got out of his car in the garage area, some of the crew from the No. 15 Michael Waltrip Racing Toyota team came over to voice their displeasure with his antics. A melee ensued between the crews with people being shoved to the ground. Bowyer hopped out of his car and ran back to the No. 24 Hendrick Motorsports hauler to confront Gordon.

NASCAR officials prevented Bowyer from entering the No.  24 hauler.

After the melee, the two drivers were summoned to the NASCAR hauler. They also addressed the situation.

Gordon said:

Things have gotten escalated over the year and I have just had it. Clint (Bowyer) has run into me numerous times, wrecked me and he got into me on the back straightaway, pretty much ruined our day. I have had it, was fed up with it and got him back.

Bowyer said:

I mean the racing — it’s just a shame. The last person in the world you want to get into anything with is Jeff Gordon on the race track. I mean, you’re down there racing, the track’s extremely slick, we’re all on tires — I didn’t even need to pass him. That’s the thing. All I was doing is riding around biding my time. The only thing I had to do is keep the 5 car (Kasey Kahne) within reach, so for him to act like that — I mean, I barely touched him and then I feel him get into turn three and try to turn me and he missed and then next thing I know Brett’s (Griffin, spotter) telling me on the radio that he’s trying to — he’s waiting on me. It’s pretty embarrassing for a four-time champion — and what I consider one of the best this sport’s ever seen — to act like that is just completely ridiculous.

NASCAR later penalized Gordon for violating Sections 12-1 (actions detrimental to stock car racing) – altercation with another competitor on the race track during the race. He has been fined $100,000, docked 25 championship driver points and put on NASCAR probation until Dec. 31. Rick Hendrick, owner of the No. 24 car, has also been penalized with the loss of 25 championship owner points. Alan Gustafson, crew chief of the No. 24 car, was found to be in violation of Section 9-4A (at all events, crew chief assumes responsibility of his driver, car owner and team members) and has been placed on NASCAR probation until the end of the calendar year.

Bowyer’s crew chief Brian Pattie violated Sections 12-1 and 9-4A and has been fined $25,000 and placed on NASCAR probation until Dec. 31.

Rick Hendrick, owner of Hendrick Motorsports issued a statement:

I’ve always respected Jeff for standing his ground. We also respect that NASCAR needs to police the sport and send a message when situations like this occur. It’s been a great year, and we’re going to put our focus on finishing in a positive way this weekend.

Gordon added:

I take responsibility for my actions on the racetrack. I accept NASCAR’s decision and look forward to ending the season on a high note at Homestead.

Michael Waltrip Racing also issued a statement:

The goal of Michael Waltrip Racing is to be a championship-level organization both on and off the track. The on-track incident which occurred during Sunday’s NASCAR Sprint Cup race at Phoenix International Raceway was extremely disappointing and brought raw emotions of a long and hard championship battle to the surface. Though we generally cannot control certain actions on the track, the unfortunate reactions off the track Sunday did not live up to the professional standards in which Michael Waltrip Racing expects all of its representatives to live by. We commit to our sponsors, our manufacturer, our fans and NASCAR that we will do so in the future.

See the incident here:

Harvick said:

I’m looking forward to finishing out this season on a strong note with RCR and continuing to build our program going into the 2013 season with the ultimate goal of winning a championship. Anything beyond that, once I know what my future plans are set, I’ll let you know.

In 2014, Harvick will join the SHR stable, which includes Tony Stewart, Ryan Newman, and Danica Patrick.

RCR owner Richard Childress wouldn’t talk about the rumor:

I’ve got a contract for 2013 and this is 2012. I’m not talking to you about nothing (regarding that).

Harvick has 18 career Sprint Cup victories, and has driven for RCR since his Cup career began, the week after Dale Earnhardt Sr was killed in a crash at Daytona International Speedway.

In 2010, Harvick considered leaving the team, but decided to stay in good faith. This time, he chose to leave because he thinks SHR will provide motivation that seems to be lacking at RCR.

RCR shrunk to three cars this season, after Clint Bowyer left due to a lack of sponsorship. Reports indicated that Bowyer had a sponsor lined up, but RCR wasn’t interested. As a result, Bowyer left to join Michael Waltrip Racing and had arguably the best season of his career.

Childress’ grandsons both drive in NASCAR’s lower levels. Austin Dillon is driving in the Nationwide Series, where he sits third in points. Dillon will drive the No. 33 in the Daytona 500 next season.

Ty Dillon drives in the Camping World Truck Series, where he sits second in points.

Childress is grooming RCR for his grandsons to eventually take over. While there is nothing to indicate that this has anything to do with Harvick’s decision, it is possible that it does.

Paul Menard and Jeff Burton have been struggling this season, with both out of the top 15 in the standings and winless.

Elliott Sadler, who drives the team’s Nationwide Series entry, is tied for the N’Wide series points lead. He will not return to RCR next season. He is rumored to be close to a deal with Joe Gibbs Racing. Ty Dillon could move up to the Nationwide Series next season.

Update: Stewart was asked to comment on the rumor. He said:

Well, it’s actually Dale, Jr. And (NASCAR reporter) Marty Smith is actually going to be in the fourth car. Yes, that’s where we are at. I will tell you this, when we have something to tell you guys, we’ll tell you. I’ve always said that. You guys can throw darts, but when we have something to tell you that’s different than what we’ve got going on, we’ll obviously tell you.

Update 2: Kevin Harvick is said to be taking Budweiser and Jimmy Johns with him to Stewart Haas Racing in 2014.

With surgical precision, polesitter Jimmie Johnson triumphed at one of his best race tracks, gathering steam toward a sixth NASCAR Sprint Cup Series title while fending off a strong performance from his closest challenger for the championship.

Holding off Kyle Busch during a five-lap closing green-flag run at Martinsville Speedway, Johnson won Sunday’s TUMS Fast Relief 500 at the .526-mile short track and grabbed the series lead from sixth-place finisher Brad Keselowski.

Johnson’s fourth victory of the season and his seventh at Martinsville — tying him for third all-time with Rusty Wallace and Hendrick Motorsports teammate Jeff Gordon — leaves the five-time Cup champion in a familiar position. Johnson holds a two-point lead over second-place Keselowski with three races left in the Chase for the NASCAR Sprint Cup.

“I’m ecstatic about the win today and ecstatic about the point lead, but this is no cakewalk,” Johnson said. “I feel as focused and as prepared as I’ve ever been. We have some very smart guys with experience on this team, and everybody is managing their emotions well and working very hard on their individual positions.

“Our young group of over-the-wall guys, they’re standing the test of time. They’re dealing with a lot of pressure each time on pit road and executing very well.”

Busch finished second, .479 seconds behind the driver of the No. 48 Chevrolet, who won for the 59th time in his career.

Kasey Kahne ran third, followed by Aric Almirola and Clint Bowyer. Dale Earnhardt Jr. finished 21st in his return to racing after a two-week hiatus. Earnhardt missed two races on doctor’s orders after sustaining his second concussion in six weeks Oct. 7 at Talladega.

Johnson had the lead on Lap 491 when a chain-reaction spin involving Sam Hornish Jr., Carl Edwards and Earnhardt caused the 11th caution and set up a restart on Lap 496.

For practical purposes, however, the winning move came on Lap 476 when Johnson and most of the other lead-lap cars opted to pit for tires under the 10th caution, caused by Kevin Harvick’s blown engine.

Keselowski and Earnhardt stayed on the track and led the field to the green flag on Lap 481. Earnhardt fell back immediately, but Keselowski stubbornly clung to the top spot until Johnson passed him on Lap 486.

“I think we’ve learned our lesson here in the past in not pitting late, and that certainly came into play, and we made the right decision there,” Johnson said.

Five laps after Johnson grabbed the lead, Hornish spun Edwards in Turn 2, and Edwards’ Ford slid into Earnhardt’s Chevrolet, knocking him out of the racing groove. After the restart on Lap 496, Busch got to Johnson’s bumper through Turns 1 and 2 on the final circuit, but deft driving on Johnson’s part kept Busch at bay.

“Jimmie did a good job,” Busch said. “He’s a five-time champion, six-time champion — probably six — for a reason. Getting into (Turn) 1, I got to his rear bumper. Didn’t want to move him out of the way. He slowed the corner down, protected the bottom.

“When I went back to the gas, I spun my tires and got loose, (and) he squirted away from me. No chance of getting back to him in 3 and 4. He manipulated my car the way he needed to protect himself for the last corner down there in 3 and 4.”

Denny Hamlin’s championship hopes sustained a crushing blow when his No. 11 suffered electrical problems late in the race. After intermittent losses of power, Hamlin’s car stalled on the frontstretch on Lap 391, causing the eighth caution of the race.

By the time his crew identified and fixed the problem — a broken post on the master cutoff switch — Hamlin was 34 laps down and mired in 33rdplace, his finishing position. Hamlin dropped from third to fifth in the standings, 49 points behind Johnson and all but out of contention for the title.

Johnson’s victory gave Chevrolet its 10th straight Cup manufacturers’ championship and 36th overall.

But that was the only thing that went wrong in Saturday night’s Bank of America 500 at Charlotte Motor Speedway. Saving fuel over the final 56 laps of the closing green-flag run, Clint Bowyer snookered his Chase for the NASCAR Sprint Cup rivals in winning his third race of the season and the eighth of his career.

Bowyer, who won for the first time at Charlotte and the first time on an intermediate speedway, beat Denny Hamlin to the finish line by .417 seconds. Jimmie Johnson, who like Hamlin and Bowyer was saving fuel over the final run, came home third. The top three finishers trimmed a significant portion off Brad Keselowski’s series lead.

“I want to do a burnout!” Bowyer lamented in Victory Lane. “Am I ever going to get to do a burnout?”

Keselowski ran out of fuel before his final pit stop and finished 11th. Keselowski leads Johnson by seven points and third-place Hamlin by 15 at the midpoint of the Chase. Bowyer climbed to fourth in the standings, 28 points back.

“Realistically, we’re still in the thing,” Bowyer said. “We’ve just got to keep doing what we’re doing. Talladega (where Bowyer was the victim of a 25-car last-lap crash and finished 23rd) was a huge setback, but what a great way to bounce back and get pointed back in the right direction.”

Bowyer moved from Richard Childress Racing to Michael Waltrip Racing this year, and the depth of success in their first season together has been a pleasant surprise.

“It makes you almost giddy,” Bowyer said. “It’s so much fun to come to the racetrack knowing that you’ve got cars that are capable of getting the job done . . . Who would have thought in a million years, after making the switch and coming over to a new family, and everything that was new, that we’d be in Victory Lane three times?

“With five races left, we’re still in contention for a championship our first year together.”

Greg Biffle ran fourth, Kyle Busch fifth and Mark Martin sixth, as only six cars finished on the lead lap

Keselowski, who started 20th, gained track position by pitting under the first caution on Lap 12 and then staying out when the rest of the lead-lap cars came to pit road under the third yellow on Lap 37. From Lap 42 through Lap 166, the race ran caution-free, and when NASCAR threw the fourth yellow for debris in Turn 1 on Lap 166, the caution restored all the lead-lap cars to the same tire cycle.

All except Johnson, that is. Curiously, Johnson was the only driver to take two tires (right sides) as opposed to four during pit stops on Lap 168. The No. 48 Chevrolet restarted the race in the lead on lap 173, but Johnson quickly lost six spots to cars with fresher rubber.

With a three-wide move to the outside on the restart, Biffle took the top spot, but his stint at the point was short-lived. Keselowski slipped past Biffle on lap 180, pulling Hamlin with him, and began logging laps at the front of the field.

A debris caution interrupted the proceedings on lap 223, but it didn’t deter Keselowski, who led the field to a restart on Lap 228 and began to pull away from Kyle Busch. Johnson and Hamlin came to pit road to top off their fuel cells under the caution — whereas Keselowski did not.

Ultimately, that cost the driver of the No. 2 Dodge, who ran one lap too many before his next stop and ran out of fuel before getting back to pit road on Lap 276. Keselowski’s car stalled in the pit box, and by the time he was back up to racing speed, he was 13th in the running order.

Johnson and Hamlin pitted on Laps 279 and 280, respectively, and were confident they could make it to the checkered flag without stopping again. They did — but so did Bowyer.

Neither Hamlin nor Johnson was particularly thrilled at having to back down his speed to save gas, but they were consoled by the dent they made in Keselowski’s points advantage.

“We ran around in circles and were done,” Johnson said sardonically when he entered the media center for his post-race press conference. “It’s a tough way to race, for sure, but I’m happy that as a group and a team, we’ve figured out how to get better at fuel-mileage racing.

“It’s something that we didn’t have in our repertoire for a lot of years. So I’m very pleased with the progress we’ve made, that I’ve made in the car. My driving style just eats up fuel. Making good changes, and playing the game the way it needs to be played right now, and closed in a little bit on that No. 2 car (Keselowski).”

Subbing for Dale Earnhardt Jr., who was sidelined by a concussion, Regan Smith turned in a strong performance in the early going of the first race without an Earnhardt since 1979 and the first race without a driver from North Carolina since 1961.

Smith ran as high as ninth and was firmly in the 10th spot when his engine expired on Lap 61, ending his first run for Hendrick Motorsports.

“I think the important part was that we had a really fast race car,” Smith said after exiting the No. 88 Chevrolet. “We had a good first adjustment there, went just a little too far with it and got a little too free.

“Needed one more stop and I think we would have had it dialed in . . . It’s disappointing.”

Smith will get his second shot in the car next weekend at Kansas Speedway.
