Small Block Chevy Suffix Codes: 3N - CDR
GM body designation. All these are identified here. Quickly, A = Chevelle, F = Camaro, X = Nova. If you're looking at the engine code - this is already known. If you're looking at the casting # information and it mentions 3970010 "A/F/X/Y/B".... basically this means "it's used in everything", whereas if it simply states "Y"... this means Corvette.
