LS6 5.7L without ECM and Wire Harness - 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 Corvette’s 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 water 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!
