COMP Cams® and RHS™ join forces to eliminate the “performance dysfunction” that plagues GM ZZ4 crate engine owners

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 Cams® is dedicated to producing top quality components that draw the most power and torque from any engine platform. As a result of this effort, 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 provide your ZZ4 with extra 16–92 horsepower, as well as bullet proof reliability.
