LSX B8 Long Block

Chevrolet Performance CPP LSX 376-B8 long block crate engine assemblies allow you to build boost on a budget. They utilize LSX Bowtie standard-deck blocks, and add blower-friendly 9:1 forged pistons combined with the LS3 high-flow, rectangular-port heads. The LSX376-B8 is designed for lower-boost applications, up to about 8 lbs. That's suitable for most supercharger and turbo kits that are designed to be used with production-based applications.
