More info
As heart of the Corvette ZR1, the supercharged LT5 6.2L SC is the most powerful engine ever offered in a regular production Chevrolet. It features a more-efficient, more-compact 2.6L Eaton R2650 TVS supercharger. That’s enough to generate more than 9 pounds of boost and help produce 755 horsepower and 715 lb.-ft. of torque.
The LT5 is based on the same Gen V Small-Block architecture as the LT4 & 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.
