The COMP Cams LS1 275T Thumpr hydraulic roller cam delivers a choppy, thumping idle and higher performance for street use. It works acceptably with a stock torque converter but performs best with a 2000+ rpm stall converter and appropriate gearing. This cam suits drivers seeking a pronounced lope and stronger street power while accepting a louder idle character.
