Comp Cams CL31-600-8 "Thumpr" Hydraulic Lifter Camshaft and Lifter Kit
Fits 1963-1995, Ford 221-302 cu.in. small block V8

The newest line of camshafts from Comp Cams is the "Thumpr". This line of retro-fit hydraulic roller and hydraulic flat tappet cams is designed for use in engines that originally used a flat tappet cam. It will give a significant increase in horsepower over an identical flat tappet grind. The "Thumpr" uses lobe profiles and grind characteristics that produce an early valve opening, long exhaust duration, and a generous overlap to give the engine a powerful and hard hitting exhaust note and a rough idle without sacrificing power output or streetability.

The Comp Cams "CL" cam and lifter kit includes the camshaft, the appropriate lifters, Comp Cams assembly lube, full instructions, and decals.
