I built and 1800 CC race engine for a NASA 914 ( dynoed at 96 RWHP at 5000 RPM and 108 torque from 2800 to 4600 RPM) This engine was to replace one that
totally ruined one cylinder (Chinese 96MM) after a very short time. I took this engine apart and found a new cam and lifters. The marking on the cam are
"C 2 O" Large C small 2 and what looks like a large O (partially obscured by the gear. Any one know who made this cam ????
