About Product:
The Thumpr™ Camshafts are a series of hydraulic flat tappet and hydraulic roller Camshafts that are now available for most popular applications, carb and late model EFI. The reason that the new Thumpr™ Camshafts have such an aggressive exhaust note is that the lobe profiles and grind characteristics chosen by the COMP Cams(R) engineers produce a combination of early exhaust Valve opening, long exhaust duration and a generous amount of intake and exhaust overlap to maximize the rough idling characteristics of the cams without negatively impacting the power output or streetability. Thumpr™ cams deliver incredible muscle car sound and a new level of streetable performance.
