Chevrolet Performance is thrilled to offer the LS9 6.2L supercharged 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, including titanium intake valves, are used, along with 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 sustains it longer through the rpm band for broad, on-demand power, whether off-idle or at speed.
Chevrolet Performance’s LS9 crate engine assembly includes the dry sump oil pan and provisions for the charge cooler’s liquid cooling system. You’ll need an external oil tank,* external coolant tank* (for the charge cooler), and ECU/wire harness to get the baddest production LS engine of them all up and running in your project vehicle. It also includes a nine-bolt crankshaft flange that may require an adapter for use with some transmissions.
*Not currently available from Chevrolet Performance. Check with your Chevrolet Performance dealer for updates.
