Engineers from RCR designed and built this Chevrolet 400ci R-99 cast-iron small-block with aluminum heads. It produces 870 hp and redlines at 8,000 rpm. It is one of three in existence, and Team Gordon has the other two. This horsepower is constantly available for Gordon's trigger-happy right foot. Gordon drives the NASCAR NexTel No. 31 Cingular Monte Carlo for Richard Childress Racing (RCR).
