If you are going to revive a dead thread, you better get your info straight. The current Sprint Cup motors is based on the R07, which is a new motor designed strictly for racing. It shares nothing with the LS motor except for the traditional two valve/pushrod design. The lower end NASCAR series do use the LS2 block, but they make 500-600HP not 800HP @ 9000RPM like the big boys
