The COMP Cams Thumpr 227/241 hydraulic roller cam is a street-oriented swap cam that provides a signature lumpy idle and strong midrange character. It’s intended for high-performance street use; a stock converter can be acceptable but works best with a 2000+ rpm converter and appropriate gearing. Expect a choppy/thumping idle as part of its street-friendly personality.
