Anyone have one? How bad are they? On paper it says only 30tq/15hp difference. One thing is the 4.6 is more common than the 5.4, so if you need a new motor, you can get one cheaper and easier. You can also do just about anything to the 4.6 that you can to a mustang.
Opinions?
I had an 1998 F-150 ext. cab with a 4.6 it was lifted, 3" flowmaster, K&N Filtercharger and a superchip. It moved pretty well I must say.....I also had a 03 Supercrew with a 5.4 and I really couldn't tell a whole lot of difference in the two. Not too sure with an Expedition how a 4.6 would be tho. My 2003 Expedition 4x4 had the 5.4 and it wasn't nearly as peppy as the trucks were.
