GM Performance Parts teased us during 2008′s SEMA show about the coming availability of an LS9 crate engine and yesterday we received word that the heart of the ZR1 is now available through GM dealers. MRSP for the 6.2L Supercharged ZR1 V8 is listed at $28,000 with the GM dealer price set at $21,000.
The 6.2L LS9 is rated at 638 horsepower and 604 lb-ft of torque. A limited 24 month/50,000 mile limited warranty is included.
The package comes fully dressed including the ignition system, supercharger assembly, exhaust manifolds and the dry-sump oil pan. The external oil and cooling tanks as well as an ECU/wire harness are not included. Also not included is the Corvette ZR1 â€œBlue Devilâ€ engine cover. GM Performance Parts does plan to release a LS9 controller kit and a front accessory drive kit later in 2009.
From the GM Performance Parts Catalog:
The most powerful regular-production engine ever from GM! The New LS9 6.2L supercharged – the standard engine in the 2009 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 from GM, but the quickest and fastest, too! GM Performance Parts is thrilled to offer the LS9 6.2L in a fully dresses 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 castings and steel cylinder liners that are honed with a deck plate installed to maximize performance and cylinder seating. High-rpm-validated lightweight reciprocating parts, including titanium intake vales and connecting rods, are used along with high-flow cylinder heads that flow the charge forced on them by 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.
