The Chevy 632 is the largest displacement big block V8 ever offered in a Chevrolet crate engine package. It produces 1,004 hp and 876 lb-ft of torque from 632 cubic inches of displacement, all naturally aspirated, all on 91 to 93 octane pump gas. No turbo. No supercharger. No nitrous. Just bore, stroke, head flow, and proper tuning. For drag racers, pro touring builders, and hot rodders chasing the highest numbers possible without forced induction, the 632 is the answer.
The bottom end is built around a forged steel crankshaft, heavy-duty forged connecting rods, and forged aluminum pistons in a 4-bolt main cast iron block. The 4.60 inch bore by 4.75 inch stroke combination is what unlocks the 632 cubic inch displacement and the torque curve that makes the engine drivable in a heavy car. High-flow aluminum cylinder heads and a high-rise single-plane intake manifold deliver the airflow needed to make over 1,000 horsepower without exotic fuel.
The 632 is overkill for daily driving and that is the point. This is a build core, a finished show car powerplant, or a no-prep race engine. Drop it in a 1969 Camaro, a 1965 Chevelle, a Pro Mod hot rod, or a heavy-duty truck pulling a sled, and there is more than enough power for any application that does not need forced induction.

Was nervous spending this much on a used engine but the team at Vaz walked me through every spec, sent the dyno sheet, and confirmed BBC mount fit before I paid. Engine arrived perfectly. Tri-Five with a 632 is exactly the build I wanted. Worth every dollar.
I have built three big blocks before and this 632 is the most impressive Chevy crate motor I have ever bought. Vaz ran it on the stand, sent me oil pressure and compression numbers, and shipped it crated like a piece of glass. Made over 1,000 hp on my dyno on the first pull with my own tune. Chevelle runs 9.40s in the quarter.
