LT4 Engine: The Supercharged Powerhouse Behind Modern American Muscle
One of General Motors' most sophisticated small-block V8 engines, the LT4 is built to provide exceptional performance right out of the factory. With a 6.2-liter displacement and an Eaton TVS supercharger, this engine generates amazing horsepower without sacrificing daily drivability. When it first appeared in high-performance cars like the Cadillac CTS-V and Chevrolet Corvette Z06, it immediately raised the bar for factory-built muscle.
