19260165 - LS9 6.2L Supercharged Crate Engine 638 hp / 604 lbs torque

The new LS9 6.2L Supercharged - the standard engine in the 2009-2013 Chevrolet Corvette ZR1 - is a technology marvel that holds the distinction of being the most powerful regular-production engine ever offered in a GM car. It helps propel the 3,324-pound ZR1 from 0-60 in 3.4 seconds and through the quarter-mile in an astonishing 11.3 seconds at 131 mph - all the way to a top speed of 205 mph! Those stats make the ZR1 not only the most powerful car ever produced by GM, but the quickest and fastest, too!

GM Performance Parts is thrilled to offer the LS9 6.2L in a fully dressed crate engine package. And while it shares the 6.2L displacement of other LS engines, this one is unique, with stronger block casting, stronger cylinder head casting and steel cylinder liners that are honed with a deck plate installed to maximize performance and cylinder sealing.

High-rpm-validated lightweight reciprocating parts, including titanium intake valves and connecting rods, are used along with high-flow cylinder heads that flow the charge forced on them by a sixth-generation supercharger. A revised, higher-helix design delivers 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. A dual-brick charge cooler is integrated on a unique manifold system that mounts the "blower" in the engine's valley, with charge cooler on top.
