The COMP Cams Thumpr 283Th hydraulic roller camshaft is a high-performance street profile that produces an aggressive, choppy idle and broad torque. It works acceptably with a stock torque converter but performs best with a 2000+ rpm converter and lower gears. The cam gives a distinct exhaust note and is aimed at muscle cars and street rods seeking strong midband punch.
