Pour On "Z" Power
GM's ZZ4 engine has great performance potential straight out of the crate; but in today's realm of high-performance engines, 350 hp is not exactly something you brag to your buddies about. Comp has designed bolt-on GM ZZ4 power packages that dramatically improve the horsepower, torque, and "fun factor" associated with this engine.

Test results prove that carefully selected combinations of Comp Performance Group products can transform your stock ZZ4 into a small-block powerhouse with bullet proof reliability. Each Comp Cams Performance package has been dyno tested in-house to demonstrate real world, repeatable results. After completing Stage 1 of the five performance packages, select the level of horsepower you desire from the four remaining stages to deliver dependable, streetable power
