Product Details

The COMP Cams Mutha' Thumpr Hydraulic Flat Tappet Camshaft line is built for Ford V8 owners who want the aggressive, choppy idle of a big-cam street machine. These hydraulic flat tappet cams are also called Thumpr cams. They give you a muscle car sound and a performance power curve, and they work with a hydraulic lifter valvetrain.

Key Features:

  • Hydraulic flat tappet design for simple, maintenance-friendly operation
  • Lobe profiles designed to produce the rough, lopey idle the Thumpr line is known for
  • Made by COMP Cams, a well-known name in performance camshafts and valvetrain components
  • Suited to street, street/strip and cruiser builds
  • Part of a line with multiple camshaft options, so you can choose the one that matches your engine combination

Pair the camshaft with matching hydraulic flat tappet lifters, valve springs, pushrods and a break-in lubricant. Follow the manufacturer's recommended break-in procedure for flat tappet cams. Choose the specific camshaft from the options on this page to match your engine and performance goals.
