Jamie McMurray ended a massive losing streak in dramatic fashion, beating Kyle Busch by a bumper to the finish line of the Pepsi 400 on Saturday night.

McMurray snapped a 166-race winless streak by drag racing with Busch for much of the final two laps at Daytona International Speedway. The cars appeared to touch several times on their final trip around the famed track, and McMurray nosed across the finish line a mere 0.005 seconds ahead of Busch.

It denied Busch a shot at a rare double victory — he won the rain rescheduled Busch Series race 12 hours earlier — but finished second in the main event. He then blamed a lack of cooperation from his Hendrick Motorsports teammates for failing to help him win the race.

"There were a few opportunities for them to get behind me and push me," Busch said. "Especially (Jeff Gordon), he chose not to do so and stayed up high and helped another Roush car."

McMurray, one of the Roush Fenway Racing drivers, benefited with his first trip to Victory Lane since 2002 when he scored his only career victory as a replacement driver for an injured Sterling Marlin at Charlotte. The win came in McMurray's second career start, a NASCAR record, and anointed him as the sport's newest star.

But expected success never followed as McMurray struggled through the next four seasons. Those down times were not lost on him in an emotional Victory Lane.

"I always said for five years, however long, there would never be another victory like Charlotte," McMurray said. "And you wait so long to win. Every driver out here can tell you how special it is. I started crying, and I'm like, 'Why are you crying?' Because I was so happy. Celebrating."

Kurt Busch finished third and was followed by Carl Edwards, Gordon and Greg Biffle.

Clint Bowyer, Matt Kenseth, Kasey Kahne and Jimmie Johnson rounded out the top 10.

Tony Stewart was denied a chance to climb the fence for a third consecutive year when he wrecked with teammate Denny Hamlin as the two were leading the race just 14 laps in. Stewart, the two-time defending race winner, finished 38th and Hamlin was last in 43rd.

"We've got two guys who are very competitive, running up front, we've got real good cars and this is something that can happen," team owner Joe Gibbs said. "It's just one of those unfortunate things."

Busch thought his own situation was unfortunate as he pondered his second-place finish while McMurray celebrated.

The four Hendrick drivers — Busch, Gordon, Johnson and Casey Mears — were all at the front late in the race and had to pick and choose their spots on the track. But Busch often seemed to be on his own, as Johnson and Gordon took turns lining up behind Mears when he was leading, then working together on the outside as Busch stayed low.

So Busch wasn't surprised when he had no help getting past McMurray on the final two laps, and he said he "got blown off" by Gordon when he tried to congratulate him on Victory Lane.

"I guess I'm on the outside looking in now," Busch said. "I'm probably not going to be invited to the team meetings next week. I think bliss is over at Hendrick Motorsports for Kyle Busch. We're getting ready for 2008."

Older brother Kurt tried to put the situation in perspective.

"At the end of a race, a restrictor-plate race, you don't have any teammates," Kurt Busch said. "The advice I would offer to Kyle is understand you are out their working as your own individual."

McMurray was the benefactor of all the Hendrick drama, winning despite an early penalty for driving under the yellow line. It was a redemption of sorts for a driver who suffered through a terrible 2006 season, his first at Roush.

He negotiated his way out of his contract with Chip Ganassi Racing in a highly publicized battle between car owners jockeying to put McMurray in their car.

So it was a disaster when McMurray finished a career-worst 25th in the standings, scored only seven top 10 finishes and ran through two crew chiefs.

He hand-picked Larry Carter for this year, raising the stakes for him to win this season. So when he finally crossed the line, he wasn't sure he had won and couldn't tell because of all the screaming on his radio.

There was no such confusion for Stewart, the heavy favorite to win for the third straight year. But just like the Daytona 500, when he wrecked with Kurt Busch while leading, Stewart was knocked out in another fluke accident.

The Joe Gibbs Racing drivers were running first and second 14 laps into the race when Hamlin wiggled, Stewart ran into the back of him and the two careened into the wall.

Stewart, who is still seeking his first win of the season, was angry with his teammate.

"He just wrecked two really good race cars. He tried to wreck us in practice on Friday and didn't get it done, at least he finished it off today," Stewart said. "He's a young guy and he wants to be successful, but I don't know if he knows what the definition of team is right now."

Hamlin, coming off his first win of the season last week in New Hampshire, didn't want to debate Stewart.

"If he wants to blame it on me, I'll be the bigger man and take responsibility for it," Hamlin said. "He's been around this sport longer than I have and he probably knows more than I do, so I'll just take it for what it's worth."

Gibbs, meanwhile, tried to play peacemaker as he watched his crews hammer away at sheet metal as the race roared on around them.

"Both our guys are very aggressive, they love to race, they are good teammates and they want to win every race," Gibbs said. "Sometimes guys get upset, which is understandable."

The Gibbs accident collected three other cars, including Dale Earnhardt Jr., who had hoped to celebrate the return of his suspended crew chief with his first win of the year. He finished 36th, just one of several drivers sent home disappointed.

Kevin Harvick, the Daytona 500 champion, was run into the wall by Juan Pablo Montoya and finished 34th. Clint Bowyer, Harvick's teammate, led 49 laps early but dropped off the pace with an electrical problem. He battled back, was in position to win until the Hendrick cars ganged up on him, and wound up seventh despite leading 55 laps.
