The COMP Cams 321QnHR-10 camshaft is optimized for 454 ci engines with good cylinder heads, calling for 11:1 compression and a 4,500+ rpm stall converter. This profile targets high output in big-block configurations and is best installed in engines prepared with compatible heads and supporting systems to handle the elevated compression and stall requirements necessary to reach intended power levels.
