Introducing one of the most powerful production-available GM Crate motors available to the public - The 6.2L LT4 Direct-Injected V8 outfitted with an Eaton 1.7L Supercharger - 650 crank horsepower and 650 crank Ft. Lbs 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.
