Seth is correct. Stick with the stock engine because everything fits as it should without any hassles. Installing an 8BA requires lots of modifications that snowball into a "project" requiring changes that you weren't aware of like fan pulley and water pump changes.
You need 8RT water pumps and the fan blade clearance problem must be solved. In the photo above you can see the custom made adjustable alum. fan pulley and alternator bracket.
plus, the Y-bracket fender brace must be removed. I made "angle iron" supports bolted to frame as shown in Post #6 above.
