COMP Cams Camshaft 54-600-11

Description

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.
