  The new LS9 6.2L supercharged

When the C6 Corvette ZR1 went out of production, so did its unique LS9 6.2L supercharged engine. Chevrolet Performance acquired a finite number of them for use as crate engines and when they’re gone, they’re gone! 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. Our 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 (not available from Chevrolet Performance), external coolant tank (for the charge cooler) and our LS9 controller kit, P/N 19299462, to get it running in your project vehicle. It also includes a 9-bolt crankshaft flange that may require an adapter for use with some transmissions.
