Chevrolet Performance 19431955 - Supercharged LT4 Wet Sump Crate Engine - 650HP

The supercharged LT4 6.2L SC is the most powerful engine ever offered in a regular production Chevrolet. It features a more-efficient, more compact 1.7L Eaton R1740 TVS supercharger, which spins at up to 20,000 RPM. That generates more than 9 lbs of boost and helps produce 650 HP and 650 lb.-ft. of torque. The LT4 is based on the same Gen V Small-Block architecture as the LT1 engine, with several unique features designed to support its higher output and the greater cylinder pressures created by forced induction. They include Rotocast A356T6 aluminum cylinder heads that are stronger and handle heat better than conventional castings, lightweight titanium intake valves and stronger forged aluminum pistons.
