I've talked to over half a dozen shops around here and the average is $3000-$4000. The highest was $6500 from a racing engine shop. After hearing you guys on here, the prices I've been given make me sick...
If you're close enough to run to Detroit (about 45 minutes from Toledo), I know a great engine guy near the airport that can do whatever you want to the engine including complete rebuild and machine work... He retired from the engine factory that made the 440....
