Oval-port aluminum heads deliver big power in an affordable package

Our 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. We dubbed it the ZZ454/440, and it’s an affordable high-performance big-block for any chassis you can stuff it in.

 

The ZZ454/440 uses our new cylinder block casting for greater strength and performance, while the aluminum heads use smaller, 110-cc combustion chambers to boost compression to 9.6:1, up from 8.5:1 on the 454 HO. We then match the airflow capability with a high-lift, hydraulic roller camshaft that delivers great idle quality and requires no periodic lash adjustments.

 

Our crate engine package includes the ZZ454/440 assembled with a water pump, balancer, aluminum intake manifold, and a 14-inch flexplate. Your Chevrolet Performance dealer can hook you up with the carburetor, starter, ignition system, and other accessories required to get this big-power big-block started.
