Corvette Engine Code Stamping Numbers All engines are stamped with an engine ID code which consists of a prefix and a suffix. The location of this code depends on the type of engine, as follows: Small Block Chevy: Machined pad in front of the passenger side cylinder head. Often hidden by the alterator. Big Block Chevy: Above timing chain cover. The prefix portion of the ID code tells you the assembly plant code, and the engine's production date (for example, 0701 = July 1st....no year is indicated). The suffix portion tells you the original model year / engine / transmission / car combination when it went down the assembly line. 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. Engine ID Code Example: V0107CLJ - (V = Plant, 01 = January, 07 = 7th Day, CLJ = Engine Suffix Code)
