Chevrolet Performance 19416595 - Supercharged LT4 Dry Sump Crate Engine 650HP (3-Pin)

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.

IMPORTANT NOTE: There has been a running change in the High Fuel Pressure Sensor on LT1 and LT4 production engines. It is critical that the correct engine part number and the correct engine controller be paired to ensure proper operation of the transmission. See chart:
