Yes you can put in a 180 ph engine. I have one in my '65 model and
turning a C/S prop. Check http://www.airplains.com/. The downside with
our models is that you cannot get a GW weight increase and we are still
limited to 36 gallons of LL. I love my configuration. But, my conversion
is a Bush/Doyn and I would not recommend that only because of the
owners. I am not sure it is even still available.

The other downside is the conversion cost. Going from the
Continental to the Lycoming requires the replacement of just about
everything forward of the firewall, including the nose gear.
Converting Lyc. 150/160 hp 172 to 180 hp is a lot easier and less
expensive.

I had a 145 hp 172 and this was my dream conversion. I needed the
extra climb performance in the backcountry. Unfortunately, the price
was way out of my ballpark. For the Continental conversions, I've
found that it's usually cheaper to buy one that's already been
converted.
