Thumpr Camshafts are the hottest cams to hit the streets in more than a decade. That's because they give you the big cam sound you're looking for, without the drawbacks. Applying a camshaft design originally created for sports car endurance racing, they incorporate early exhaust valve opening, long exhaust duration, and a generous amount of intake and exhaust overlap. Best of all, Thumprs will not negatively impact power output or streetability.

Features:
  • 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 duration create optimum overlap for powerful, hard-hitting exhaust note
  • Best with aftermarket converters and more rear gear

    31-602-5 - Comp Cams Thumpr Hydraulic Flat Tappet Cams is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Great cam! I bought this cam for my Ford 289 and it sounds great! I only have the original 2 barrel but I know I could tune it better with a 4 barrel, but if it sounds this good with the 2, it should be killer when I put the 4 on!
