2009 Shelby 427 Las Vegas Motor Speedway Las Vegas, NV March 1, 2009

Congratulations, Kyle Busch, for winning the 2009 Shelby 427.

Mark, who started Sunday's event in eighth place, was running in fourth when an engine issue affected his No. 5 Pop-Tarts/CARQUEST Chevrolet. "I hate it. I sure would have liked to kept racing today," Mark said. "We had a good race car. And we were getting better. And we're learning each week. We'll have to get ‘em next week."
