Doubt you will find anything. Use a dial indicator to determine the lift.

I have seen numbers stamped on the back end of cams before, but you would have to pull the cam or the rear freeze plug to see it. If it's just a curiousity thing I wouldn't go to much trouble to find out, and just tell everybody it's a 3/4 cam,  ;)

The whole thing was to identify what was in a blown up motor as to be able to recreate it one day.

A micrometer, dial caliper/digital caliper etc can be used to measure the lobes if the cam is out. If it's installed and the engine rotates use the dial indicator.

If it's and aftermarket cam it should be stamped.  If GM, and original going to be weak if from a truck.
