The COMP Cams Thumpr hydraulic flat cam (FC 279T) is designed for Ford 351C, 351M and 400M engines and targets high-performance street use. It can run with a stock converter but performs best with a 2000+ stall converter and compatible gears. Expect a choppy, thumping idle character that is typical of Thumpr-style grinds.
