The plane came with the conversion. Really makes a C-172 fly. I have the
Bush (aka Avcon or Doyn) conversion. No support from Bush of Udall, KS;
I tried when I needed some information when I purchased the airplane.
Airplains and Penn-Yann also do conversions.

Pluses:

much better climb, somewhat more speed

Minuses:

This airframe does not allow (to what I can find) for a gross weight
increase

you still have 36 usable gallons in the tank and therefore shorter legs
if you push the engine. I usually fly at 60% and try to maintain a 4
hour no reserve burn. I plan for 2.5 hours, though.

Hi Ross, can you give any details on who did and how much the
conversion cost?

We have this same airframe with the original O-300D and fixed pitch.

Thanks...
