http://www.steveweaver.com/n142mp.htm   I was looking at this plane today for sale on trade-a-plane,  it is an M20L with converted IO-550.    Steve Weaver told me that the plane was converted by a shop in FL,  I'm assuming he is referring to Coy Jacobs place.    He said Porsche offered to help with the cost of these 550 conversions.   Does anyone have any more info on that,  or know how many other L models have done this conversion?   Also,   what does everyone think about the asking price
