I've got a 1999 expedition with a seized 5.4l. I found a good 5.4 out of a 2001 F150. My question is will I need to swap the intakes as the 1999 has the aluminum intake and the 2001 has the plastic intake. Im hoping I don't have to as the motor is complete and drop in ready. Any help would be appreciated! Thank you

 

pretty sure you need to remove the intake to remove/install the engine.
as you'll have them both off anyway, use the one that will work.

 

Yep had to remove intakes to install. Both intakes will work. I ended up using the Intake off the 99 as the 2001 intake has a different location for the coolant line. Have everything all bolted back in and finished just need to put everything on the front end back together and replace the front body mounts under the cab as I had to lift the cab to get access to the top and side Tranny bolts. Other than that everything has been compatible.
