    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 to pick up an additional 30 horses, while still offering 519 ft/lbs 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.

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

    This crate engine package includes the ZZ454/440 assembled with a water pump, balancer, aluminum intake manifold, and a 14-inch flexplate. To simply finish up this package, you will need a carburetor, starter, ignition system, and other accessories. Don't sweat it, JEGS has all the components you need to get this big-power Big-Block started.
