A Mutha' Thumpr hydraulic roller cam from COMP Cams designed for high-impact street/strip use. The profile requires about 9:1 compression and a 2,500+ rpm stall, and it expects supporting intake, gears and headers. Owners should anticipate a rough idle while gaining broad torque and horsepower across the rev range for aggressive applications.
