The COMP Cams Xtreme Marine nitrided 234/244 hydraulic flat tappet cam is specified for Chevrolet small-block engines from 262 to 400 ci and tuned for marine power delivery. Nitrided for greater surface hardness, this marine grind prioritizes durable cam life and predictable midrange torque under boating conditions. It should be installed with compatible lifters and valvetrain parts and paired with appropriate intake and exhaust plumbing for marine applications.
