The COMP Cams Thumpr 227/241 hydraulic flat tappet camshaft is a street‑focused upgrade for Ford 351W applications, offering a choppy, thumping idle and stronger midrange under load. It works with stock torque converters but performs best with 2000+ stall converters and matching rear gears. Ideal for high‑revving street machines that want a more aggressive sound and improved on‑throttle response.
