Why are you replacing the motor ?
Smoking, running rough all the time, not enough power ?
Replacing a 4.0 with a 4.0 isn’t going to gain power or more mpg, just another 4.0L.
Have you considered a 5.0L out of an Explorer ?
If none of the above applies and you are after a bone stock 4.0L there are better places to buy a 4.0L than from Ford.
Start looking around your area for remanufactured engines, then maybe a 4.0L with some power options added to it.
Putting it in, you will be paying Ford a premium price for something a local shop can do a little less expensive.
Just things to think on.
