My Maule M4 has an O-300 and could really use a little more power. I have choices of the Continental IO-360 or Franklins and while I have nothing really against them, I think a carbureted Lycoming O-360 is the way to go with this. Naturally, I'm on a budget. I'm hoping for something like a mid time to high time engine that I can rebuild (under supervision from y IA, of course).
Specifically I would like to find a -C4F or -C1F, but I'll consider any variant. I'm putting a fixed pitch prop on it.
Has anyone here done this conversion?

I did, of course talk to Maule and Mod kit 17 is appropriate for my airplane. I don't suffer from the illusion that you can put any engine in any airplane and "just get a field approval". At least not unless you're friendly with your local FSDO and DER.
I do however have enough engineering knowledge to go through that hassle if I really wanted to, but the Lycoming suits me nicely.

Re: O-300 to Lyc. O-360 conversion
It's been quite a while now since the Mod kit for the Lycoming 0-360 has been approved for the M4. I kept my eyes open for almost two years and have yet to see any O-360-C1F or -C4F for sale anywhere. I wish the kit could have covered any of the -A models, because they are everywhere.
The -Cs have only ever been put into Maules, Huskies and Scouts, as far as I can tell. None of which have been produced in great numbers so there just aren't many out there.
I may need to talk to a DER to see if I can get myself approval for using a -A model and do my own engineering, but I dread completing the process without blowing my top over nonsensical paperwork.
Just took my M4 on a long trip from low level to hot and high mountains and the O-300 really doesn't cut it.
What are people's experiences with the Continental IO-360 powered M4s? I'm a bit concerned about complexity, hot starts, weight and cost and I don't really want to deal with the hassles of a CS prop either. But those engines are out there and the Mod kit too.
