ZZ454/440 Big-Block Crate Engine

Aluminum Heads Add Big Power!

GM engineers took the tough 454 HO and topped it with a set of higher-flow and lighter-weight, oval-port aluminum cylinder heads to pick up additional horses – while still delivering a stout 519 lb.-ft. of torque. The Chevrolet Performance ZZ454/440 is an excellent performer for your project vehicle!

Those aluminum oval-port cylinder heads contain 2.19/1.88-inch valves intake/exhaust. Beneath them is the latest-generation GM block casting with four-bolt main caps, and 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. This BBC includes a water pump, balancer, aluminum intake manifold and a 14-inch flexplate.
