LT1 6.2L Wet Sump Crate Engine

LT1 - The Next Generation is Here!

Introduced on the seventh-generation (C7) Corvette Stingray, the LT1 6.2L opened the next chapter in the long, historic legacy of the LT-1 moniker – and gives your project vehicle a high-tech heart transplant with an unprecedented balance of performance and efficiency!

The Chevrolet Performance LT1 is architecturally similar to the LS family of engines, but with a unique block casting, cylinder head design, oiling system and more. It also combines advanced technologies including direct injection, Active Fuel Management (cylinder deactivation) and continuously variable valve timing to support an advanced combustion system.

With this LT1, you'll get 455 hp and 455 lb.-ft. of torque; and a wet sump oiling system. Engine Controller Kits from Chevrolet Performance allow you to back the LT1 with a 4L70-E four-speed overdrive automatic, a T56 Super Magnum six-speed manual or the revolutionary 8L90-E eight-speed automatic transmissions!
