Ok so my SOHC motor is finally about done and I like the old OHV style motors and know the 98+ XLS Explorers and Rangers still had them. And from my thinking it should be a straight forward swap since 97+ the used the 5R55E auto trans or optional 5spd trans. So I'm thinking all I should need is an OBDII motor and the computer for the motor. Or is there stuff I'm missing that I need? I should be able to still use my same GEM right?

It will take A LOT of rewiring to get this to work. The SOHC and the OHV do not use the same wiring harnesses. Also, the SOHC 5R55E had extra sensors that the OHV 5R55E didn't.

Ok...thanks. I found a Ford Rebuilt SOHC with 80k with paperwork for $175.00 but the truck is no longer around to hear the motor run so unsure which direction to go on it and knew I could depend on an OHV, but don't think I want to do a bunch of rewiring.

Thanks for the link Rocks, I've read that before but unsure if it'd work the other way around using the SOHC ECU, I may just have to stick with the SOHC I like that it has good horsepower and she likes that power in the truck I just don't like the chain tensioner, guide issues.
