Anyone know of the O.S. 37 heli engine will fit in the mount for the 32 engine of a Concept 30?

I replaced an OS .32 SX-H with a .37 SZ-H in a Raptor 30. I had no issues.
Both engines have the same bolt pattern. Here are the manuals for each, to compare dimensions:

Short answer. Yes.

Longer answer. The .37 will drop in where the .32 was. You will like the .37. It's as easy to tune as the .32 and makes noticeably more power.
