CRATE ENGINES LS SERIES Corvette Z06 performance straight out of the crate! Nothing says performance like engine code LS6! Producing more than 400 horsepower, the LS6 transformed the Corvette Z06 into a world-beating sports car. GM Performance Parts now offers this ultimate small-block performer in a complete crate engine package just the extra muscle your Corvette or F-car road racer needs to sweep off the competition. The 5.7-liter LS6 builds on the inherent strengths of the Corvettes LS1 engine, but benefits from a higher-lift camshaft and higher-compression pistons to raise horsepower from 350 to 405, and torque from 340 lb.-ft. to 400 lb.-ft. Such tremendous power is produced through the use of hollow-stem valves, a more aggressive camshaft, improved intake and higher-rate valve springs. GM Performance Parts delivers the LS6 as an all-inclusive assembly, complete with Corvette-style aluminum oil pan, large-volume composite intake manifold with single-bore throttle body, and high-performance log-style exhaust manifolds. The LS6 is also a great choice for older cars and street rods whose owners are looking for high-tech performance and fuel-injected dependability! WHATS HOT?
