Posted by: admin In: Main ()
GM has announced that the blown beastie (6.2L Supercharged V8 LS9 engine) rocketing the Corvette ZR1 will be available as a crate motor next fall boasting 639hp / 604 lb-ft tq! GM Performance Parts also gives us a peek at the LSX 454 Crate Engine.
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.
