I have a 2003 f250 super duty 4x4 with a bad motor. Will a 5.4 motor from an 03 expidition fit and if so will there be any major mods or differences? I had heard that I needed to make sure it would bolt up to the trani correctly. Are there differences I need to look for before I buy the expidition? Thanks in advance...

I can't see where there would be anything major, same transmission?

I looked it up, the transmissions are different. The Expi has a 4R70W and the F250 has a 5R110W. The bolt patterns whould be the same, but you may have to swap a few sensors, but my guess is it should slide right in.
