How much should a basic 340 rebuild cost?

I think often we remember/reference the past- in my case the 1980s and half of the 1990s when one could get a desirable engine- like a pre 1972 engine that had no real wear. Doing the work ourselves we would get a kit with rings bearings and gaskets and do a sat afternoon rebuild. Hand lap the valves on the healthy heads (Guides and seats in great condition as is) and we had a hell of a great street engine and there really was no compromise in the rebuild because the core engine was so healthy. All for several hundred dollars in parts. Now those core engines are 50-60 years old and been sitting under a tree. Or if they were stored indoors, they still had a rough life when they ran. Parts are now very expensive and finding a reputable shop is difficult and thus more $$. Maybe now in our older years we don't want to tear down clean and assemble our engine. If we are to pay to have it all done it looks like $7000 to $10000 is what the cost will be- drop off your engine core needing a full rebuild- pick it up in a couple months and pay the man. This hobby is expensive and only us old geezers have the expendable income to participate on it.
