They didn't gain too much in their production vehicles because the 5.4L you quoted makes 310hp on gasoline. That's only a 10hp increase.
That Super Stallion was supercharged which makes a big difference in octane ratings and tuning.
E85 does have a higher octane rating per se, but like mentioned earlier, it takes much more fuel to make the same power. Jack Roush has a Mustang drag car with a 7L version of the new Ford 6.2L. It is naturally aspirated and runs 9sec 1/4 mile time on E85. It uses 2 injectors per cylinder to get enough E85 into the engine to make that kind of power. It makes close to 800hp.
Look at a flexfuel car's window sticker at miles per tank, in small print on E85, the distance is between 50% and 70% of the Gasoline miles per tank.
Now if E85 was about $1.25 a gallon, then it would be worth it for me to invest in a E85 vehicle, but since it isn't much less than regular gasoline, then you are shooting yourself in the foot (and wallet) buy using it.
Just a note, to keep your Hemi happy and to live a long life, it is recommended to use 89 octane gasoline. Even says so in the 08 owners manual. Not sure if it does in the 09-up or not.

I go out of my way to find 100% non-ethanol gas and here someone wants to change a Hemi so it takes 85% ethanol fuel???
I consistently get 2 mpg better in my truck (Hemi) and my Grand Cherokee (4.7 HO) with 100% gas than I do with E10.

Thanks for everybody's posts. What triggered my interest in E85 potential was the potential cost savings, given the recent high gas prices, and my finding the following site: http://www.permaculture.com/.
I guess "cost savings" is a relative term here, as if E85 causes potential long term damage, then there is no cost savings - perhaps future expense.
However if I can save $1.00 per gallon, with a $500 conversion cost and no damage to the engine, given lower gas mileage, then maybe - just maybe - it is something to consider.
Thank you.

We have an Avenger that runs both E85 and Gas and well we have never bothered in fact we debadged the e85 sticker(sorry farmers) To me it's a way the government is trying to keep the price of corn up so they don't have to subsidize the farmers.
If anything in the HEMI if you can find pure gas no ethanol you would like that. I think Shell and Canadian Tire in Canada had it don't know anymore.

well assuming that you have no problems and equal gas mileage you will take 500 gallons to recoup your expenditure...
500 gallons is 40 fillups, or about a year, so maybe...
but most people I have talked to agree that you end up paying more per mile when operating on e85 (the cost saving is not the 30% they loose in mileage), so the point is moot.

To me you are wasting your time. It's just a matter of time until the subsidies will stop propping up ethanol and ethanol will be dead. The bill to kill ethanol failed the Democratic senate by 1 vote so after 2012 I see ethanol no longer being used.

Corn grown for E85 and corn for consumption are 2 different types. E85 corn also grows in vastly more types of soil then consumption (anywhere grass grows, E85 stuff can grow.) So, E85's take off or fall will have little to no effect (more likely no) on consumption corn prices.
Corn, whether the sweet varieties, or "field corn" (animal feed) is used in so many ways, I can't expound enough here.
You are eating both kinds, and probably don't even know it - in many different ways.
Corn is corn, when it comes to growing, and any kind can be grown in a very broad array of soils, moisture, from way south, to way north.
Actually, corn is a form of grass - all corn.
