The COMP Cams Mutha' Thumpr 235/249 hydraulic roller cam is a street/strip profile that produces a rough idle and requires supporting modifications: 9:1 compression, a 2500+ stall converter, gears, intake and headers. It’s built for aggressive street performance and strip use where higher stall speeds and complementary components are part of the overall package.
