Comp Cams CL12-601-8 "Mutha Thumpr" hydraulic roller camshaft and lifter kit
Fits 265-400 cu.in. small block Chevrolet

The newest line of camshafts from Comp Cams is the "Mutha Thumper". This line of retro-fit hydraulic roller 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 "Mutha Thumper" 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.


Duration @ .050" lift: 287/305 (int/exh)
For high performance street/strip use, needs 9:1 compression,
2500+ stall, intake, gears, and headers, rough idle.
Cannot be used with stock valve springs.
