SEMA preview: GM Performance Parts 638hp LS9 Crate engine

GM has announced that the blown beast that lives under the hood of the new Corvette ZR1 will be available as a crate motor next fall. We can only imagine the possibilities that this will spawn.

With 639 hp and 604 lb.-ft. of twist available from the 6.2-liter supercharged V8, and dimensions shared by the LS3, any number of vehicles could make a happy home for the LS9. According to GM, the engine comes fully dressed, with an ignition system, exhaust manifolds and supercharger, and only needs an external oil tank and coolant tank (for the charge cooler), an ECU and wiring harness.
