Thumpr Series cam and lifter kits deliver a substantial power increase over an identical hydraulic flat tappet grind without sacrificing reliability or ease of maintenance. Thumpr camshafts are available in different grind profiles each one will produce a rough, racy exhaust note and impressive amounts of horsepower and torque within a different rpm range. This gives you a seriously aggressive exhaust note without negatively impacting the power output or streetability of the engine.
The lobe profile and grind characteristics of these Thumpr camshafts use a combination of an early exhaust valve opening, a long exhaust duration, and a generous amount of intake and exhaust overlap to maximize the rough-idling characteristics of the cams.
Looking for something that will give pretty good. valve train while producing less heat and mechanical noise. Truck will be used to tow a racecar now and then, I might put a snow plow on it, and will also be used to haul mulch etc. The best cam for a Milwaukee Eight engine depends on what you expect out of the motorcycle. In an ongoing quest to provide you with the performance and sound you demand, COMP Cams engineering team proudly introduces the Thumpr Series cam and lifter kits. Looking for an inexpensive cam that would make good power in a 350 sbc with stock vortec heads, GM perf vortec intake and throttle body. COMP Cams is bringing the muscle car sound back, and it's nastier than ever! Let's face it-few things serve to grab our attention at a car show or cruise night more than a car with a thumping, high performance idle.
