Nochallengeif 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 )
Yeah, I was thinking for the proto type, but your right, 36 engines. Hell if I were to get the Lathe and mill, then
