LT4 Wet Sump Automatic Connect & Cruise Powertrain System W/ 10 Speed

Product Details


As the heart of the Corvette Z06, 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’s enough to generate more than 9 pounds of boost and help produce 650 horsepower 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.

8L90-E & 10L90-E Series

Chevrolet Performance adapted the production-based 8L90-E eight-speed and 10L90-E ten-speed automatic transmissions for use with our LT-series crate engines. Each features four gearsets and five (8L90-E) or six (10L90-E) clutches plus creative packaging designs that enable these advanced automatics to fit the same approximate space as GM’s family of six-speed automatics. Extensive use of aluminum and even magnesium make it lightweight, too. A torque converter and controller is included with each transmission and the kit is calibrated for the respective engine it is matched with in the powertrain.
