A Factory-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 that runs on pump gas. The engine delivers exceptional air flow capability in a straight forward package even without any power adders. The LSX376 is built without an intake manifold so you can top it with a carburetor or production-style injection system or enables the installer to tailor the induction system to suit the blower or turbo system. 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.

The LSX376-B8 is delivered with only a dust cover instead of an oil pan so you can order what is correct for your application. Just one more way to keep the cost down by excluding
parts you can't use. 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.
*Horsepower and torque ratings were derived by GM Engineering using a normally aspirated LSX376 with LS3 EFI system. Your power numbers may vary, based on induction system and componentry.
