MPG difference between 460 and 351W?
What is the difference in MPG between 460 and the 351 W engines?
Assuming the same vehicle, 1990 F250 HD, with 4.10 rear, 2WD.
Also what's the MPG difference between 460 and the newer 5.4L, in F250 with 4.10 rear.

I can answer this one. 
My brother has a 1993 F250 4x4 with the 5.8L, 5 spd and 4.10 gears but the 1/2 ton axles and he gets about 14-15 empty. I get 12 - 13 empty and I have the 1 ton axles. Loaded, his mileage drops significantly while mine drops just a little. It depends on what application you are talking about. Towing 3-4k lbs should remain about the same, but if you get up to 5k + lbs, the 5.8L will probably get worse mileage from my experiences. If you are not towing, the 5.8L will get slightly better.
I don't know anything about the 5.4L, sorry.
