Build LSX Boost on a Budget

Chevrolet Performance takes the economical LSX Bowtie standard-deck block, adds blower-friendly 9.0:1 forged pistons and combines them with the LS3’s high-flow, rectangular-port heads to create an affordable foundation for supercharged and turbocharged combinations.

The LSX376-B8 is designed for lower-boost applications, up to about 8 pounds. That’s suitable for most supercharger and turbo kits that are designed to be used with production-based applications. This engine is delivered without an intake manifold and other accessories to enable the installer to tailor the induction system to suit the blower or turbo system. Our 476 horsepower and 475 torque ratings are based on testing with the production-style, normally aspirated fuel injection system. Horsepower and torque will vary with a supercharger or turbo system.
