Description, Q&A
Description. These Magnum Muscle camshafts follow the tradition of excellence that COMP Cams is famous for. These cams offer a step up from original equipment cam designs. They are stronger than stock, and are tailored to the traditional high-compression engines of the '60s and '70s, through to the design techniques of today.
