Engineered for muscle cars and street rods, the COMP Cams CL10-600-5 Thumpr Hydraulic Camshaft Kit is designed to maximize your AMC V8’s potential. This kit delivers substantial horsepower increases and a broad torque curve, making it the ultimate upgrade for classic American iron.
The Thumpr design features an early intake valve opening combined with extended exhaust duration. This unique profile creates optimal valve overlap, resulting in a powerful, aggressive exhaust sound that commands attention. It’s the sound of pure performance.
To fully harness the capabilities of this camshaft, COMP Cams recommends pairing it with aftermarket torque converters and higher rear gear ratios. This ensures efficient power transfer and allows the camshaft to perform at its peak.
Specifically designed for 1966-1979 AMC 290-401 V8 engines, this kit ensures a precise fit and reliable operation, manufactured to the strictest tolerances and rigorously tested for quality assurance.
