More than 550 supercharged hp with exceptional refinement

 

The Cadillac CTS-V’s 6.2L supercharged LSA engine delivers 556 horsepower with refinement that is rare in the world of high performance. It is smooth, quiet, and well-balanced — all while delivering breathtaking power.

A unique aluminum cylinder block casting houses a forged-steel crankshaft and super-tough reciprocating parts, integrated piston-cooling oil jets, and high-flow cylinder heads that support the airflow enabled by a 1.9L, sixth-generation supercharger with four-lobe, high-twist rotors. The advanced rotor design broadens the supercharger’s effective range, enhancing low-rpm torque and high-rpm horsepower.

Chevrolet Performance’s LSA 6.2L supercharged crate engine package comes fully dressed, from the top of the charge-cooled supercharger assembly to the ignition system, water pump, balancer, and more. It is a less costly alternative to the LS9 engine and makes a great transplant for any off-road LS-powered vehicle or pre-1976 car or truck. It also comes with conventional wet-sump lubrication system.

NOTE: This engine includes an eight-bolt crankshaft flange that may require an adapter for use with some transmissions.
