LEGENDARY PEDIGREE MEETS ADVANCED TECHNOLOGY IN A FACTORY-ASSEMBLED POWERHOUSE PERFECT FOR YOUR PROJECT CAR

Chevrolet Performance is proud to offer the all-new LT1 crate engine. Introduced on the seventh-generation Corvette Stingray, the LT1 6.2L opened the next chapter in the long, historic legacy of the small-block engine — and it gives your project vehicle a high-tech transplant with an outstanding balance of performance and efficiency.

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 to support an advanced combustion system.

Our LT1 crate engine is rated at 460 horsepower and 465 lb-ft of torque, and it is offered with a wet-sump (P/N 19328728) or dry-sump (P/N 19329997) oiling system. A controller specially designed for retro-fit application using an automatic transmission is available.
