Chevy LSX-Series Small-Block V-8 LSX376-B15 Engine Kit - 19417356
Forged Internals Support Higher Boost!
If you want to stretch the performance of a turbocharged or supercharged combination, Chevrolet Performance’s LSX376-B15 is the foundation you need! Its durable, all-forged rotating assembly supports up to 15 pounds of boost–and our ratings of 473 horsepower and 444 lb.-ft. of torque are only baseline numbers of what this engine can offer.
The LSX376-B15 includes the six-bolt high-flow, rectangular-port LSX-LS3 heads. Additionally, we deliver the engine 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.
