The COMP Cams Mutha' Thumpr 287T hydraulic flat cam is a high‑performance street/strip option for Ford 221–302 engines. It calls for roughly 9:1 compression, a 2,500+ RPM stall converter and supporting intake, rear gears and headers. Expect a rough idle as part of the cam’s aggressive street/strip tuning; it’s intended for builds where maximum mid‑range and top‑end power outweigh idle smoothness.
