The COMP Cams Classic Thumpr hydraulic flat tappet cam is a street-oriented profile for Buick 364, 401 and 425 Nailhead engines. Tuned for strong low-end and midrange torque, it works with a stock torque converter and yields a choppy, thumping idle characteristic. It targets street use where pronounced torque and throttle response are desired without extensive high-RPM focus.
