The COMP Cams 304H-R cam is designed for street/strip Chevy small-block applications that need serious high-rpm power. It requires a 3000+ stall converter, a 3.90 or lower gear ratio, and aftermarket intake and headers. Expect a very rough idle and the need for upgraded valve springs and installation hardware. Intended for experienced builders targeting aggressive power bands.
