97 expedition motor swap?

[RobertNol]

So I know I've been blowing up the forums and its been a HUGE Help to me and hopfully others.

So I've got a 97 5.4 4x4. The motors seized and I need a new motor. I was wondering what would be a direct swap? Of course a 97 5.4 would be. But how about a 99 expy or f150 5.4? Or a 99 5.4 4v out of a navi? 2003 expy or f150 5.4?

Right now I'm on a budget and need something thats going to be the most direct swap..

Again I know I'm blowing up the forums but I plan on buying and pulling my motor this weekend so I'm kinda of rushed. Thanks for understanding and the help so far.

So I found a few answers and tell me if I'm wrong. But If i use the 99 expedition 5.4 with the 97 wireharness, intake manifold, and I have to custom fit the ECT.. also a custom tune which is fine.. but I'm a little confused a custom tune like a shop or a custom tune like a edge tuner? Also I read that a stock 99 tune from the dealership is fine as well and that's around 100... from what I read.

The differnt heads cause the computer to run bad ( as far as i know) but a edge tuner will NOT fix that, a full custom tune should. Not sure about the dealer tune?? Maybe possible. ( that's for 5.4 2v only) AS for the other motors Nav 5.4 4v is a great motor but you'll need the computer with the motor ( also they run Permium Gas $$$)
you also can't use the newer 5.4 3v head, you'd need the computer.

Others should have more thoughts !!

Where would I get a full custom tune and about how much would that cost?
