No challenge if someone already built it. [&:] Besides if I can pick up 9 engines from swap meets of the same displacement for cheap, then make the mount and gear set, it would be a lot less expensive that way.

Um , , More like 36 engines of the same displacement ..... Best be buyin that lathe and milling machine
( That is , if we're still thinkin bout that B-17 )
