O360 and CS Prop conversion for C177

[luvflyin]

A 68 C177. Not a C177A. What does it take to put the 180hp engine and constant speed prop on. Who has the STC? Do parts have to be fabricated?

I wouldn't, unless I couldn't part the airplane I had or had significant investments (radio paint interior) in it. Just buy one with 180 horse already in it.
