    Thumpr Camshafts are the hottest cams to hit the streets in more than a decade. Applying a design originally for endurance racing, they combine early exhaust valve opening, long exhaust duration, and generous intake/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
