Pretty sure with the 4.125" crank that the stock FE windage tray will fit. I've had 4.25" stroke engines fit with the stock windage tray and no mods, although I've heard other people had problems with that combination. In any case, its not a big deal to cut a slot or two into the factory windage tray if you need clearance for the rod bolts. There won't be any block or pan clearance issues.
