The COMP Cams Big Mutha' Thumpr 242/257 hydraulic flat tappet cam is a street/strip unit for Ford 429/460 that demands high compression and stall speeds for its full potential. It delivers very rough idle and substantial top-end authority when properly matched. Requires roughly 9.5:1 compression, a 2800+ RPM stall converter, and supporting intake, gears and headers for intended performance and driveability in aggressive builds.
