COMP Cams Mutha' Thumpr 235/249 hydraulic roller camshaft for high-performance street and strip use. This cam requires supporting upgrades—9:1 compression, a 2500+ stall converter, upgraded intake, appropriate gearing and headers—and produces a rough idle characteristic of aggressive grinds. It is intended for applications where strong midrange and top-end performance are prioritized.
