In my purchase research, I have found 3 engine shops that will take on the IO346 engine. All were contingent on a servicable crankcase, crankshaft and camshaft. G&N quoted me a price of $21-22000 for overhaul, Chuck Ney quoted $20000, and Poplar Grove Airmotive quoted $17900. Only Poplar Grove in their quote stated this was with new cylinders, and overhaul to new limits.
