The Big Mutha' Thumpr nitrided hydraulic flat tappet cam from COMP Cams is built for street/strip Chevrolet big-block 396–454 applications. It favors 9.5:1+ compression and a 2800+ rpm stall converter, with matching intake, gears and headers for best results. Expect a very rough idle; the nitrided finish provides enhanced surface hardness for aggressive use.
