I'll post pics on the resulting new cowl. I think it'll work out fine. The only thing is, I really don't need to cut much if anything from the bottom of the cowl and the part of the muffler that extends beneath the plane is behind the cowl pretty much. SO I won't have any air flow around the engine. I guess that's okay though. I have a temperature gauge so I can check the temperature without the cowl immediately after a flight and again with it, the same way.
