Yeah Dave, you are going to have to find one of the first 4-stroke planes or one of the last pre-widebody designs if you want a plane for that motor that doesn't look like a bloated dead whale. I can't remember what prop I ran on my 140L, but 17x9 or so rings a bell. So you have to take prop size into consideration. I think you should just let me have the motor for my P-51...

PS. that summit above is a gorgeous airplane!
