Old magnum MP cam info

That's just what I remember being talked about when this came was a current production part.
I'm looking possibly using it in a magnum engine with a Hughes cam extender and mechanical fuel pump eccentric.
How would this cam be in a 3/4 ton truck that tows? Is there any way to verify what it's actual specs are without sending it to someone with a "cam doctor"? I don't know who I'd even send it to for that
