C GM19299306 For builders who want to stretch the performance of a turbocharged or supercharged combination, we've got just the foundation you need. These Chevrolet Performance LSX 376-B15/450 HP crate engines feature a durable, all-forged rotating assembly to handle up to 15 lbs. of boost! Chevrolet Performance's engineers started with the tough LSX steel Bowtie standard-deck block and added a forged steel crankshaft, forged connecting rods, and forged pistons. Then they topped off the short-block assembly with high-flow, rectangular-port LSX LS3 6-bolt aluminum heads for supercharged and turbocharged combinations. The engines are delivered without an intake manifold and other accessories, allowing you to tailor the induction system and other features to suit the forced-induction setup of your choice. Due to the number of application variations, the engines are supplied with a dust shield instead of an oil pan, Any LS-style oil pan and pickup that will fit your chassis can be used. Also, the LSX376 valve covers do not include provisions for mounting the ignition coil brackets. Aftermarket or custom relocation brackets must be used.Chevrolet Performance LSX 376-B15/450
