Not sure what would need to be replaced,but you really should replace whats in there with the exact replacement.This way,you wont have any surprises.

when you find out , let me know. i have a 5.4(second one in that pickup) and i would put in a 4.6 if it isnt too much of a problem. as far as im concerned, TRITONS ARE JUNK! it will go to a new home once i get it fixed. GIVE ME A FE OR A Y BLOCK ANYDAY!

That's pretty funny considering some guys on here have 3 to 400,000 miles on there trucks.

Find a 5.4 out of a 99 to 03 F-150. It will go right in.
You need to adjust the exhaust system,put a 5.4 torque converter in your tranny and some custom tuning of your computer.
Not much to it really.
I can link you to some swap notes if ya want. Just let me know.
