The COMP Cams Big Mutha' Thumpr 243/257 hydraulic roller cam is a street/strip profile that delivers aggressive power and a very rough idle. It requires substantial supporting modifications—9.5:1 compression, a 2800+ stall converter, gears, intake and headers—to perform properly. This cam is targeted at builders seeking a high-energy street/strip character with pronounced idle behavior.
