I have been on the hunt for a good Mooney for a few months now. I have owned a J-Model in the past and cannot give up my love affair with the Mooney. I have a purchase pending on a mid-time M20F with elec. gear that the previous owner did not fly much. Put a 0 SNEW IO-390 and a new Harzell 3-blade. Of all the talk about the 390, does anyone have actual performance and cost (fuel and maintenance) experience with this upgrade. I love the -360 but wondering if I'm walking into a nightmare here. Thanks
