No cam card

I have been trying to collect info on degreeing a cam with no cam card. So far I have read that it prob. will not happen accurately/consistently even if I were to map out the cam.

I have read that I can remove the cam and send it out to be professionally measured but Id rather not do this cause its not the cam I plan to run with in the long run. Only trying at this point to gain the experience with the cam.

I am sure that the cams are stock slant cams, one would be original for the 1983 engine it is in and the other would be a recent replacement for the 1986 engine it resides within.

I have read that the cam may be marked with manufacturer and even possibly a # that I can use to get the cam specs from manufacturer.

Can anyone tell me if these cams are indeed marked in some way with an identifying # and where I might find it?

Thanks
