^ pretty much what he said. i believe the heads MIGHT be different as well. definitely the intake and flex plate though, you actually might be able to swap that from the bad f250 motor as well as the intake. there might also be a few minuscule sensors and stuff that might be different too.
A friend of mine started to do a explorer engine swap into a crown vic and i believe he had to swap the oil pan, timing cover, intake, and intake related parts. But should be cake since it would be like a short block swap.
That is how the ford techs replace a motor (or sometimes even rethread a head) on the ford trucks.
They pull the body off the frame with a lift.
My uncle’s independent shop in columbus doesn’t have a lift, and he had to replace a motor in a 98 f150. He said it was a pain in the ass to get the motor out of the truck without taking the cab off it.
