As the heart of the Corvette Z06, the supercharged LT4 6.2L SC is the second most powerful engine ever offered in a regular-production Chevrolet.
Engineered for supremacy
The LT4 features a 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 640 horsepower and 630 lb.-ft. of torque.
