COMP Cams Thumpr 227/241 hydraulic roller camshaft for high-performance street use. It creates a pronounced, choppy idle while delivering a torque-focused powerband suited to spirited street driving. A stock torque converter may be acceptable, but the grind performs best with a 2000+ stall converter and lower gearing to keep the engine in its optimal power range.
