I recently bought a 2000 F150 4x4 lariat in good shape. It's sporting the 5.4L with the 4R100 and 4406E tcase, 172k miles on the clock. This engine is rated at 260 hp, 350 ft lbs...
This will be my new DD. Plans are to modify it to get better fuel economy. A little research turned up with underdrive pulley kit nets 2 mpg, an electric cooling fan another 2 mpg. Not sure on these figures, but they will be on the list. Also going to tune it with an SCT X3 handheld. Right now its getting 13.8. I found the upstream DPFE hose disconnected, so I hooked it back up but its pulled a little tight, so i might get a longer one if it comes loose again. Members on other forums are claiming 20-22 mpg's at 65-70 mph with simple mods. If i get 20 mpg empty, I'll be happy. Thinking of supercharging this with an M122 from a 2012 GT500, this may or may not help with fuel economy, but will make for an even more fun to drive truck...
