    A factor-built foundation for forced induction Boost on a budget. That’s what you get with the LSX376-B8. 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. We deliver the LSX376-B8 without an intake manifold and other accessories to keep the price lower and enable the installer to tailor the induction system to suit the blower or turbo system. Put this great engine in a vehicle originally equipped with an LS engine to give it a stronger bottom end for forced induction, or drop it into a street rod or classic muscle car body for a modern update.
