The COMP Cams CS 283T Thumpr hydraulic roller cam is built for high-performance street use, delivering an aggressive exhaust note and strong mid-range power. It can work with a stock converter but performs best with a higher-stall converter (2000+ rpm) and lower gearing; expect a choppy or thumping idle as part of its characteristic street-oriented sound and power delivery.
