LS6 2004 Corvette Z06 Gen III V-8

Corvette Z06 performance straight out of the crate! The LS1 was a milestone in efficiency, performance, and power. Then, the GM engineers outdid themselves by taking the LS1 to the next level with a bigger cam, intake, and more compression. We call this amazing 350 cubic inch small-block the LS6, and you'll see the LS6 as standard equipment in the amazing C5 Corvette Z06 and Cadillac CTS-V. Together with the sophisticated engineering from GM, these two cars utilize the LS6 small-block to dominate their class.

The 5.7L LS6 builds on the inherent strengths of the 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, an improved intake, and higher-rate valve springs.

GM Performance Parts delivers the LS6 as an all-inclusive assembly, complete with CTS-V aluminum oil pan, larger-volume composite intake manifold with single-bore throttle body, and high-performance log-style exhaust manifolds.

The LS6 has helped to take the C5 Z06 Corvette and the Cadillac CTS-V to new levels of performance. Let the same General Motors engineering, testing, and horsepower take you to a higher level of performance.
