Comp Cams GK08-600-8 "Thumpr" Hydraulic Roller Camshaft and Kit
Fits 1987-1998, Chevrolet 307-350 cu.in. V8s originally equipped with factory roller cam,
and most crate engines, except LT1 and LT4.

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.
Comp Cams "GK" kits for the "Thumpr" Series of cams includes the appropriate gear drive and a carefully matched set of lifters. The gear drive uses precision machined and heat treated gears made from steel billet for the ultimate in durability and timing accuracy. The crank sprocket has three keyways which enable up to 4 degrees of advance or retard.
