    Thumpr Camshafts are available in three different grind profiles, each one of which will produce a rough, racy exhaust note and impressive amounts of horsepower and torque at a different rpm range. Their cutting-edge hydraulic roller design means that they will deliver a substantial power increase over an identical hydraulic flat tappet grind without sacrificing reliability or ease of maintenance. So look no further than the Thumpr line of camshafts - engineered to deliver that much sought-after ''thumping'' idle quality to everyone.

    Features:
  • Retro-fit hydraulic roller design will fit all factory flat tappet equipped Small Block Chevy and Ford Windsor
  • 3 grinds to fit all of your cruising and street performance needs
  • Long exhaust duration and other grind characteristics produce a powerful, hard-hitting exhaust note
  • Excellent horsepower gains and broad torque curve deliver real seat of the pants performance
  • Designed for use with the latest in valve train component advancements such as Beehive Valve Springs, Pro Magnum Roller Rockers and Magnum Pushrods
