Technical question on "mild cam"

I recently bought a '75 Dart Sport with a 360. The guy I bought it from said it "has a mild cam", but he didn't have specifics because the guy HE bought it from didn't say. The engine runs great, currently, but I intend to tear it down when I strip the body down for paint. Now, the question:

How can I tell what cam it is, so I can get proper specs on valve adjustment? I'm new to non-stick internals.

I thought about just measuring the valve lash as it sits, just to get a ball park. Either that, or sink the money into a new cam, lifters, rods, er cetera, but I really don't want to spend that much if I can help it.

Thanks!
Unless you measure it you won't know what it is. Lift is easy with the valve cover off. Duration is more complicated to measure. Otherwise you have to take it apart and look for numbers.
