Bowyer, the 2008 series champion, ran in front when a four-car accident occurred just before the leaders crossed the line for the final lap of the two-lap overtime finish. The Richard Childress Racing driver had the dominant car, as he started on the pole and led a race-high 48 laps.

"I can't begin to tell you what this place means to me, my family, everything you ever worked for to come to Daytona, let alone win a race here," Bowyer said. "This is the best place to come see a race, and people got their money worth tonight."

Bowyer led the way on the final restart and got a big push from Busch to help him fend off a challenge from Edwards on the second to last lap.

"Kyle gave me a good push there at the end, and luckily the caution came out, because who knows what would have happened on that last lap," Bowyer added.

Last year, Bowyer won the spring race at Bristol for his only victory during his championship season. The Richard Childress Racing driver is running a limited schedule in the series this year.

Busch moved ahead of Edwards just before the race-ending caution to take second. He increased his lead to 172 points over Edwards, who came in third.

"We're proud of that second-place effort, that was the best we had," Busch said. "Clint's car was better than ours today."

Joey Logano and Kasey Kahne rounded out the top-five.

Brad Keselowski, Brian Vickers, Justin Allgaier, David Ragan and Kevin Harvick finished sixth through 10th, respectively.

Kertus Davis was among several drivers who crashed in the closing laps, which set up the overtime finish. Davis' car erupted into flames while he tried to nurse it back to the pits after the incident. He quickly exited the car and suffered no injuries.

Kerry Earnhardt's car also engulfed in fire and smoke after he was involved in an incident with Chase Austin in the late-stages. Earnhardt was not hurt, but did suffer smoke inhalation.

"I hit (Jeff Green) and (Austin) both and then hit the wall and had a little bit of a fire, so I had a little inhalation of the fire and fumes," Earnhardt said.

Earlier in the race, Earnhardt and Donnie Neuenberger crashed after making contact on lap 10, forcing the first caution and then setting up a double-file restart. One month after the Sprint Cup Series began using the double-file restarts throughout each race, NASCAR instituted the new restart format for its second-tier division, beginning at Daytona.
