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.
Connect & Cruise Crate Powertrain Systems provide factory-matched engine-and-transmission combinations that include specially calibrated controllers and wire harnesses designed for retrofit installations in older vehicles. Connect and Cruise packages are available for a wide variety of crate engines which can be paired with an automatic or manual transmission.
