This COMP Cams Thumpr hydraulic flat-tappet cam for Chevrolet big blocks targets high-performance street use. It can work with a stock converter but performs best with a 2000+ stall converter and lower gearing, producing a choppy, thumping idle while delivering stronger midrange and exhaust character favored by classic muscle builds seeking an assertive tone and improved power.
