Kyle Busch, #5 Cheez-It/CARQUEST Monte Carlo SS, was involved in a single-car incident during the morning practice session. Busch, who was uninjured in the incident, was forced to his backup car. As a result, the current Chevrolet SB2 engine will now power Busch’s Monte Carlo SS in tomorrow’s Samsung 500. He was one of six drivers scheduled to start the Samsung 500 in the newly introduced Chevrolet R07 engine. #20-Tony Stewart, #11-Denny Hamlin, #18-J.J. Yeley, #25-Casey Mears and #96-Tony Raines will start the 334-lap/501-mile race with the R07. #33-Scott Wimmer was scheduled to run the engine but didn’t make the race when qualifying was cancelled.(GM Racing PR)(4-15-2007)
