Big Block Chevy Suffix Codes: Q - YZ
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.
Abbreviations: AB = Air Brakes, AR = Air Injector Reactor, CA = California,
HD = Heavy Duty, hdc = heavy duty clutch, HP = High Performance, LP = Liquid Propane Gas,
PG = Powerglide, mt = manual trans, mt-3, 3 speed manual, SHP = Special High Performance,
TH = Turbo Hydramatic, ti = transistor ignition.
Induction is one (1) 4 barrel carburetor unless specified.
