From what I can tell by looking at the front it's a GM Cam, it has that barcode on the bottom like they all do. But no numbers are printed on the face. The only thing is the letter D and 1928 are engraved on the cam. I have called CBM who built my motor, they don't know since they built it several years ago. If anyone has any info I'd appreciate it.

GM stamped cams with the last 4 digits of the part number and 1928 doesn't look to be any of them. I hope that's not a regrind.

GM cams usually have a bar code, looks like a pyramid.
