Description

Big Mutha' Thumpr-Extremely rough idle, needs stroker motor and/or ported heads. Major horsepower gains to 6800 rpm. Best with 3.73+ gears and 2500 stall. Compatible with stock valve springs, requires cam phaser upgrade and custom tuning.

COMP Cams Thumpr camshafts have three unique cam designs for each application that deliver excellent horsepower gains and broad torque curve; perfect choice for muscle cars and street rods. Early intake valve opening and long exhaust durations create optimum overlap for powerful, hard-hitting exhaust note. 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. They work best with looser converters, more rear end gear, and other performance engine modifications.
