Butler Performance Inc. » Comp Cams
For more than 35 years, the COMP Cams mission has never changed: to produce the highest-performing products possible, provide customers with superior service, and to lead the industry in technological development. COMP Cams has never forgotten that performance is defined by results -both at the track and on the street. Choosing a camshaft and valve train products isn't like buying an oil filter. Everything in your valve train is part of a complex interlocking system that needs to perform well as a combination. Butler Ls, the only place you need for Comp Cams.
