Chevrolet Performance LSA 6.2L 376 C.I.D. 556 HP Supercharged Long Block Crate Engines

Chevrolet Performance LSA 6.2L 376 c.i.d. supercharged long block crate engines deliver 556 hp. Powering the Cadillac CTS-V Series and the Chevy Camaro ZL1c, these powerhouses have the forced induction of the 1.9L sixth generation supercharger. They make up for the comparative lack of valve lift by packing the combustion chamber full of air and fuel, and delivering 551 lbs.-ft. of torque—along with excellent idle quality and "right now" throttle response. And the LSA comes with a conventional wet sump lubrication system. It's quiet, smooth, and well-balanced, all while delivering supercharged power—with remarkable refinement and the best dollar-to-horsepower value.
