Help ID this camshaft
Solid lifter from a small block and it's cast iron. These are the only marks on it except an "AX3' cast between the middle lobes. It was in my '69 350 when I bought it. I yanked it out because I didn't know the correct valve lash. The local Chevy dealership and speed shop struck out on who made it and what the specs are. Can you help me identify this stick?

The 7141 is the end of the part # but I could not find anything on it. I would look up those #'s in the vete finders book. I did find this link to cam #'s but Yours is not on there. There is a 7140 but its for a 12:1 motor. Here is the link.

according to this link you have chevy part number 3927140, try measuring the lopes and compare to cam specs.

and the "-140" cam was casting #3927141 - the "7141" will appear raised on the rough core portion of the cam. If you don't see a raised "7141" on it, I'd question its originality.
