You could probably get a good idea from lift alone but there are a lot of cams out there now and a lot of them have just about the same lift.
There are usable specs out there for a 336, 308, Andrews, Megacycle, Crane? Chances are it's a 336 but . . . . Either way you will need to time it in order to see how it is timed. Chances are if it's a 336 it is timed 3* advanced but it might be timed straight up since it has the old style oil pump drive. I suggest reading a few books on timing cams. Other inmates know how to post the specs. There is two more recent cam threads that have most of the specs I referred to. Some inmates don't like cam discussions. It gives them a headache. It is a bit more complicated than removing grips!
