An exceptional choice for muscle cars and street rods, the COMP Cams Thumpr Camshaft And Lifter Kit is the answer to the lifelong question of "What camshaft will give my vehicle a heart thumping high performance sounding idle?". With a design originally crafted for sports car endurance racing, this inimitable camshaft optimizes rough idling through a lobe profile and grind characteristics that utilize a combination of an early exhaust valve opening, a long exhaust duration, and an appropriate supply of intake and exhaust overlap.
The Thumpr's progressive design makes certain that the outstandingly powerful exhaust note does not compromise the power output or street efficiency of your engine. For different needs, COMP Cams made their Thumpr camshafts available in a selection of grind profiles. These various profiles generate a powerful and race appropriate exhaust note that's coupled by elevated levels of horsepower and torque within different rpm ranges. The COMP Cams Thumpr Camshaft and Lifter Kit comes with everything you need to generate the big cam sound you've been looking for. The whole package includes a Thumpr Camshaft, lifters, assembly lube, decals and a detailed instruction manual.
