Forged Internals Support More Boost!
For builders who want to stretch the performance of a turbocharged or supercharged combination, the Chevrolet Performance LSX376-B15 crate engine is the foundation they need! Its durable, all-forged rotating assembly supports up to 15 pounds of boost. Our ratings of 473 hp and 444 lb.-ft. are only an indication fo what the LSX376-B15 is capable of.
Chevy Performance engineers began with an LS Bowtie standard block and added forged crankshaft, connecting rods and pistons. The short block assembly was then topped off with high-flow, LSX-LS3 6-bolt rectangular-port heads to create an affordable foundation for supercharged and turbocharged combinations. GM delivers the LSX376-B15 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.
Our horsepower and torque ratings are based on testing with the production-style, normally aspirated fuel injection system. The power you make with a supercharger or turbo will vary. Above Added: Thu June 13, 2019, 9:34 am PST
