LT CRATE ENGINES
The Chevy LT crate engine was introduced on the seventh-generation C7 Corvette Stingray and GM’s full-size trucks and SUVs for 2014. Also known as the Gen-V Small-Block, it ushered in the next era of historic engines. Structurally, the Gen-V Small-Block is similar to the Gen-III/-IV engines, including a deep-skirt cylinder block. And when it comes to our latest high-tech horsepower, we offer the 650-horsepower supercharged LT4 from the Corvette Z06 and Camaro ZL1. See how the LT engines compare in horsepower, torque, and other technical specifications.
