Experience the pinnacle of GM engineering with the legendary Chevrolet Performance LS9 6.2L supercharged V8 crate engine. Originally engineered to power the C6 Corvette ZR1—the ultimate track-dominating supercar of its era—the LS9 is built to deliver massive, effortless power across the entire RPM band.
Featuring an integrated Eaton four-lobe roots-type twin-rotor supercharger pumping out 10.5 psi of boost, the LS9 churns out an astonishing 638 horsepower and 604 lb-ft of torque right out of the box. To handle this immense pressure, the engine is constructed around a robust, reinforced aluminum block with six-bolt main bearing caps, premium forged aluminum pistons, titanium connecting rods, and a forged steel crankshaft.
For high-performance restomods, pro-touring builds, and custom street machines, the LS9 provides supercar performance with factory reliability. Every engine comes fully assembled and ready for installation.
