4.6L vs 5.4L
#31
All FX4's from 04-08 were 5.4's. Post picture if you get it! Also I would do a vin search like someone else said before buying it, I see trucks at dealerships every once in a while that have fx4 stickers and are advertised as that but really are just an xlt. I don't think that is the case with the truck you are looking at (I bet it has the 5.4) but just throwing that out there.
