If the crank can be turned down .010" (maybe .020") and is an 8409 and it passes magnafluxing, it will probably work. Nice jouranl radii are a plus, but if it's not turned yet, that's moot because they could get ruined during the grinding if the grinder isn't careful. That's a lot of weight to be carrying around an airshow! The crank grinder is probably the guy to ask if it'll work, but make sure the guy you take it to is quite aware that you want the journal radii to be as large as possible. If your cowling's not built yet, I don't see a problem with the prop hub length because it'll just put your prop a little further out in front of the plane (a good thing from a streamlining standpoint). I'd think the safety shaft length could change, but that would depend on whose fifth bearing setup you're talking about. I can't answer that one for Roy's or Dan's. Mark Jones or Joe Horton could tell you about Dan's, or it might be located on Dan's website at http://www.fly5thbearing.com/5thbearing.html .
