The COMP Cams High Energy CRB 268H-10 hydraulic flat tappet cam is a replacement profile for 383 Magnum and 440 engines, delivering strong midrange torque and a smooth idle. Best used with a 650–750 CFM carburetor and a dual-plane intake manifold, this grind increases low- and mid-range response and pairs well with supporting bolt-on upgrades to realize its torque-oriented characteristics.
