  • For builders who want to stretch the performance of a turbocharged or supercharged combination, we've got just the foundation you need: Chevrolet Performance's new LSX376-B15, featuring a durable, all-forged rotating assembly to handle up to 15 pounds of boost. Chevrolet Performance's engineers started with the tough LS steel Bowtie standard-deck block, added a forged-steel crankshaft, forged rods, and forged pistons, then topped off the short-block assembly with high-flow, rectangular-port LSX-LS3 six-bolt aluminum heads for supercharged and turbocharged combinations.

    The LSX376-B15 is delivered 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. It's perfect as an economical replacement for a late-model performer or a great choice to build a high-boost powerplant for a Pro Touring classic.

    *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.
