The 5.4 is a great engine, I have one in one of my f150. Ford should of never put one in a 3/4. If this truck would of been a diesel or v-10, it would have been gone the first day, especially if it had been one of the few 2003 with the 7.3 diesel. very nice truck and love the set up, and there are a lot of people who would not have a diesel period. Good luck with the sale
