The COMP Cams mechanical roller 327D-R12 cam is a pro-stock style profile targeted at very large engines—500ci or larger—with specialized cylinder heads like Boss, SVO or TFS. It suits high-power race builds where valvetrain and induction are matched to extreme output. Intended for purpose-built engines where pro-stock geometry and supportive components are already part of the package to handle the cam’s demands.
