GM's LS9 6.2L supercharged V8 makes the 2009 Corvette ZR1 the fastest production GM car ever. GM Performance Parts has announced that the 638 horsepower engine will be available as a complete crate engine package.
The LS9 crate engine is ideal for enthusiasts that want to add even more power to their vintage Corvettes and project cars. The crate engine comes with the ignition system, supercharger assembly, exhaust manifolds, etc. Those that are interested in the crate engine will need to also get an external oil tank, external coolant tank (for the charge cooler) and an ECU/wire harness.

PRESS RELEASE:
GM PERFORMANCE PARTS SET TO UNLEASH THE SUPERCHARGED LS9 CRATE ENGINE
LAS VEGAS - The LS9 6.2L supercharged V-8 is the power behind the most powerful and fastest production car in GM’s history - the 2009 Corvette ZR1. In the third quarter of 2009, it will be available as a complete crate engine package from GM Performance Parts. It delivers a stunning 638 horsepower (476 kW) and 604 lb.-ft. of torque (819 Nm).
The LS9 crate engine will be the ideal all-in package for enthusiasts and racers who want the ultimate LS power plant for their project cars, from resto-modified vintage Corvettes, muscle cars and street rods to late model F-bodies and “shoebox” Chevys. The supercharger and charge cooler are integrated in the engine’s valley for a lower profile, allowing creative builders to fit the engine in a variety of applications with plenty of hood clearance.
The engine’s 6.2L displacement is shared with the LS3, but the LS9 is built for high-revving power with a supercharger. It uses stronger cylinder head castings 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, are used, along with high-flow cylinder heads that draw the charge forced on them by a sixth-generation supercharger. A new, four-lobe rotor 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.
GMPP’s LS9 crate engine assembly comes fully dressed, including the ignition system, supercharger assembly, exhaust manifolds and more. It also includes the production dry-sump oil pan and provisions for the charge cooler’s liquid cooling system. Builders will need an external oil tank, external coolant tank (for the charge cooler) and an ECU/wire harness.

Poke fun at a 638HP crate motor that murdered the GTR? I think not.

Price?
I bet it's in the neighborhood of $20k.

LS7 is currently just above 20k at 640HP.
More like 25k and over depending on options. Unless they discount the LS7 and slide the LS9 in its place.

"new business model for GM: sell parts!"
Oh c'mon now. I've seen better one liners from you. Having an off day?
Crate engines are nothing new for GM. We can actually buy a variety of motors all over the country (and world), and not have to steal a Honda to get the coveted 4-banger they can't find in junkyards anymore.
Anyone got a 72' or 73' Vega wagon kicking around they wanna sell? I suddenly have the urge to build a project over the winter. ;)
