The COMP Cams Mutha' Thumpr 235/249 hydraulic roller cam offers a similar aggressive street/strip ramp in a roller design for Ford 429/460 applications. It produces a rough idle and is aimed at builds that pair cam profile with supporting hardware. Expect best results with 9:1 compression, a 2500+ RPM stall converter and upgraded intake, gears and headers to unlock the cam’s powerband.
