Key Features
Aluminum-Headed Big-Block Value Champion
Chevrolet Performance engineers took the 454 HO � with its super-tough, all-forged reciprocating assembly � and matched it with a set of higher-flow, oval-port aluminum cylinder heads resulting in 469 hp and 518 lb-ft of torque. They dubbed it the ZZ454/440, and it's an affordable high-performance big-block for any chassis you can stuff it in.
