Comp Cams K11-601-8 "Thumpr" Hydraulic roller camshaft and kit
Fits 396-454 cu.in. big block Chevrolet V8s

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.


Duration @ .050" lift: 235/249 (int/exh)
For high performance street/strip use, needs 9:1 compression,
2400+ stall, intake, gears, and headers, rough idle.
