Chevrolet Performance 19260165 - Supercharged LS9 Crate Engine - 638HP

Free Shipping on the incredible 638hp LS9 from SDPC!

Chevrolet Performance is thrilled to offer the LS9 6.2L supercharged engine in a fully dressed crate engine package that includes every one of the Corvette ZR1’s 638 horsepower! The LS9 is a technological marvel. High-rpm-validated lightweight reciprocating parts are used, including titanium intake valves and a pair of high-flow cylinder heads that draw the charge forced on them by a sixth-generation supercharger. It has a high-helix (twist) design that helps the “blower” deliver greater power at the low end and sustain it longer through the rpm band for broad on-demand power whether off-idle or at speed.
