Comp Cams 20-603-9 "Big Mutha Thumpr" hydraulic roller camshaft
Fits 1964-2000, Chrysler 273-360 cu.in. V8s

The newest line of camshafts from Comp Cams is the "Big Mutha Thumper". 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 "Big 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: 243/257 (int/exh)
Valve lift: .533/.519 (int/exh)
