COMP Cams Thumpr 226/241 hydraulic flat camshaft for Cadillac 425, 472 and 500 applications is tuned for high-performance street use, offering a choppy or thumping idle character. While it can work with a stock converter, it performs best with a 2000+ rpm stall converter and appropriate gearing to realize stronger midrange and street-oriented power delivery.
