E85 in the 4.0?

The FFV 3.0 is not the same as the non-FFV 3.0. To run E85 you need the special programming for the PCM which non-FFV vehicles don't have.
Also, FFV (flexible fuel vehicles -- in this case gasoline and ethanol) vehicles need larger injectors for the same power level -- it takes more ethanol per unit of air to get the proper mixture. 3.0's with the FFV system have injectors closer to that of a 4.0. A 4.0 FFV would need larger injectors still.
There are some considerations on the sealing materials used in the fuel system as ethanol is very corrosive to many organic molecules. It may be that most modern vehicles use compatible materials -- but you still have the issue of the ratio control and injector sizing to deal with.

lol! I have the factory manuals on CD, and I have a 3.0 FFV and have looked into it. I wasn't born knowing Fords...
Actually, I wasn't much of a motorhead at all until I bought my first pickup about 5 or 6 years ago. I just did routine work on my vehicles to save money. The truck took me over the edge into obsession.

I have thought about the injector capacity and the use of E85. It seems that it would work fine if you do not try to run at or near full power. The computer would increase the amount of fuel until it reached the capacity of the injector.
Of course that might be like playing Russian Roulette not knowing the power rate at which is goes lean. However, I think it would work fine in an emergency if you played it safe by accelerating and driving slow.
