GM Chevrolet Performance LSX 454 Long Block Crate Engines

Chevrolet Performance LSX 454 long block crate engines are built with an all-forged, super-tough rotating assembly and feature a pair of new Chevrolet Performance deep-breathing LSX 6-bolt cylinder heads. They also come dressed with great looking, all-new orange powdercoated valve covers with an engraved LSX454 logo. With a carburetor and high-flow Chevrolet Performance intake manifold (sold separately), these engines are good for about 627 hp and 586 lbs.-ft. of torque. Due to the number of application variations, the Chevrolet Performance LSX 454 long block crate engines do not include an oil pan, and the valve covers do not include provisions for mounting the ignition coil brackets.**REPLACES 19355573 WITH 19417357**
