Sorry, seen it was a 5 speed. What gears are in it? Check all your brakes to make sure they are not dragging. Change all fluids with a good tune up and k&n drop in air filter, not an aftermarket FIPK kit they sell. From what all I know, that's the best you'll be able to do. What are you getting for mileage now?

You won't see any gains unless the air pump is partially seized.
3.55 gears, larger tires, slow down.

I agree with what's been stated. I saw my MPGs double when I cut my cat out... 5.5 to 11 mpg. It was plugged, and you'll notice the drop in power and the inability to reach 55 mph if it's plugged.
A good tune up, stock sized tires, keeping the speed low, and properly setup up gears, lubed bearings, and properly set brakes will be the best improvements you'll see for no big outlay in cash.

my '97 f-super duty w/460 gets at best 6, and routinluy gets around 3 towing a trailer. you wouldnt think you could flow that much fluid through an injector

Yeah, that's about as good as you're going to get. I wouldn't spend too much money or effort trying to get any better.

5.13 gearing.if he's lucky,4.88's......but he doesn't sound lucky lol.surprising really that all the f-super duty (f450's) didn't all just get the diesel engine.
when it comes to pickups,your largest economy gains will be working on aerodynamics.not focusing on the engine.especially with the 460,where there isn't much to be gained anyway.i still have much to do myself.
