Hey I'm in the In a situation where I have replace my current engine in my Christavia (experimental champ) it current has a 0-290 Gpu the cylinders need major work and has had a prop strike so I'm thinking the most economical way is to replace. I want to replace with a small continental like a c90 or a 0-200 I am trying to determine which one would be the best choice there is a c90 that may be available now my question is are they the same I see that many parts are interchangeable. And as that I'm experimental I could build a stroker out of it if I wanted?
