Chevrolet Performance Parts Largest Displacement, Most Powerful Crate Engine Ever!
632/1004hp Crate Engine
GM Crate Engines are horsepower rated to SAE Standards.
The Big Block V-8 reaches peak power at 6,600 rpm and revs to a recommended maximum of 7,000 rpm. Fuel is delivered by eight port injectors with the engine breathing through CNC-machined high-flow aluminum cylinder heads featuring symmetrical ports. While Big Blocks have traditionally been designed with variations in port shape from cylinder to cylinder, all eight intake ports of the ZZ632 have the same length, volume and layout. Similarly, all of the ZZ632’s exhaust ports are identical. This symmetry ensures individual cylinders all produce similar power.
