The COMP Cams Big Mutha' Thumpr 243/257 hydraulic roller cam is a street/strip profile that delivers strong mid-to-top-end power. It requires roughly 9.5:1 compression and a 2,800+ rpm converter stall, and performs best with intake, gearing and header upgrades. Expect a very rough idle; this cam suits aggressive builds that accept a harsher idle for added power.
