Now take into account a typical truck the 5.8 came in. A 1995 Bronco has a curb weight of 5,000 pounds. An Expedition has a curb weight of 5,800 pounds. My EL comes in at almost 6,200 pounds. The 5.8 Windsor would be so taxed to move the vehicle compared to the 5.4 it’s fuel economy would be abysmal. And that is unloaded.
