LT1 Wet Sump Crate Engine

Fifth Generation Chevrolet Performance
The LT1 6.2L opened the next chapter in the historic legacy of the Small-Block engine—and it gives your project vehicle a high-tech heart transplant with a balance of performance and efficiency. Our crate engine is rated at 455 horsepower and 455 lb.-ft. of torque.
The LT1 is architecturally similar to the LS family of Small-Block engines, but with a unique block casting, cylinder head design, oiling system and more. It also combines advanced technologies, including direct injection and continuously variable valve timing. See page 115 for the recommended controller.
