Chevrolet Performance ZZ454/440 Crate Engine

Chevrolet Performance took the tough 454 HO and matched it with a set of higher-flow, oval-port aluminum cylinder heads to pick up an additional 30 horses.

Aluminum oval-port cylinder heads are mounted on our latest-generation block casting with four-bolt main caps, which is filled with an all-forged rotating assembly for exceptional strength and durability. There is also a high-lift hydraulic roller camshaft for excellent drivability and a broad performance range.

The crate engine package includes a water pump, balancer, aluminum intake manifold and 14” flexplate.
