Feel like 360 should have more power

This would probably be a decent grind.

The smart thing to do would be to have the heads worked get them milled no more than .030". Then install the cam as I recommended and put a performance ignition curve in the distributor. I think the short block is probably ok. You have cylinder pressure that describes a stone stock engine with a big cam in it.
