My guess is that you have an aftermarket timer that uses Shovelhead points cam.
The mark on earlier cams pointed toward the "breaking edge" of the narrow lobe, for the front cylinder. Once you distinguish the difference from the wide lobe on yours, you can follow the usual procedure discussed elsewhere on this forum. Instead of working a control cable, you will have to twist the points cam with your fingers, or a pair of hemostats.
