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. The combination of physical force and sophisticated engineering is what really makes the LT4 engine unique. It can dependably handle high boost levels thanks to direct fuel injection, forged internal components, and sophisticated cooling systems. Because of this balance, the LT4 is a popular among builders looking for a reliable base for high-horsepower street or track projects as well as performance purists.
