Comp Cams CL11-600-8 Thumpr hydraulic lifter camshaft and lifters
Fits 396-454 cu.in. Chevrolet V8s

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

Duration @ .050": 227/241 (int/exh)
Cannot be used with stock valve springs.
High performance street, stock converter ok, best with
2000+ converter and gears, choppy/thumping idle.
