Only that through experience that the O200 is going to be quite heavy for that airframe, it has the same installed weight of the Viking 130, if that is the route you are going be sure to mindful of nose weight, and having to add weight to the tail.. -Alissa

Oil cooler, improving baffling on #3 cylinder, light weight starter and alternator, composite or wood prop. I have o-200 on 601xl not sure about 701 but I think they do like a light engine, 

It will never be STOL. Too heavy. You will likely need lead in the tail. IMO it ruins the purpose of the plane...extreme STOL. The one I know routinely rolls 1200 feet solo on TO in hot wx.

I have O-200 in my 601 XL.  My first and biggest game changer was a Vetterman exhaust system.   I changed that only and what a difference.  Also I put 9.5:1 pistons,  E-Mag, light weight starter and alternator.  I'm pretty happy with it now, burns 5.3 gal in cruise.  Yes it's heavy but reliable.
