The blacktop motor has slightly stronger pistons that have whats known as a "cooling channel" where the oil from the piston squirters remains in the piston for a little while longer creating cooler piston crown temps. The blacktop engines also should have the updated S14 style water pump which reduces the cavitation problem in the earlier redtops.
