Comp Cams Thumpr Cam With Flowmaster 80 Series
New Exhaust and front grills coming soon!**Cam Information Below**
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.
RPM Range: 2,000 to 5,800 rpm
Duration @ .050" lift: 227/241 (int/exh)
Valve lift: .479/.465 (int/exh)
Ideal for high performance street use, stock converter ok, best with
2000+ converter and gears, choppy, thumping idle.
