Description

COMP Cams Thumper Cams have early intake valve opening & long exhaust duration create optimum overlap for powerful, hard-hitting exhaust note to maximize the rough-idling characteristics of the cams. Comp Cams Thumper Cams unique cam designs have application that deliver excellent horsepower gains & broad torque curve; perfect choice for muscle cars & street rods

 They give you a seriously aggressive exhaust note without negatively impacting the power output or streetability of the engine. Thumpr camshafts are available in three different grind profiles; each one will produce a rough, racy exhaust note and impressive amounts of horsepower and torque within a different rpm range.

 

In some cases minimal engine vacuum requires mods for any vacuum accessories such as power brakes. Designed for use only with valve train upgrades, including COMP Cams Valve Springs and roller rockers. Works best with looser converters, more rear end gear and other performance engine modifications


A popular street camshaft used with pre 1985s original overhead valve OEM engines, the hydraulic flat tappet cam is commonly used up to mildly aggressive performance profiles. The flat tappet lifter has a flat appearing base (this surface is actually slightly crowned) that rides on the cam lobe face, rotating slowly within the lifter bore to promote proper oiling. Internally, the lifter features a cavity that fills with oil and a piston that is depressed by the pushrod (and valve spring). This "hydraulic chamber" provides a cushion of fluid to soften the impact on the valve train, creating room for expansion as the engine reaches operating temperature. Hydraulic flat tappet camshafts deliver quiet operation at street to mild racing engine speeds. The biggest advantage to hydraulic flat tappet lifters is that they do not require constant maintenance to ensure proper valve lash. Hydraulic flat tappet camshafts/lifters are pre-loaded at initial start-up and require little, if any, maintenance from that point forward. Flat tappet lifters can only be used once per camshaft and must be replaced due to wear patterns created by the direct contact of the cam with the lifter base.

  • Mild street performance to mild race
  • Minimal maintenance, little or no valve train noise and economical cost
