Ethanol is an oxygenated fuel. You need much more ethanol to achieve the proper air/fuel ratio than you would with gasoline.

Ethanol advantages:
1. Absorbs moisture in the fuel tank
2. Ethanol raises the octane rating (true E85 will have an octane rating of 100-105)
3. Cleans the fuel system
4. Reduces CO emissions since it is oxygenated.

Ethanol disadvantages:
1. Can result in plugging of the fuel system because of its cleaning action.
2. Raises volatility which can cause hot weather driveability problems.
3. 60,000 to 70,000 BTU per gallon compared to 130,000 BTU per gallon of gasoline which means you will use alot more of it.
4. Absorbs water and settles out with the water when sitting.

I see no reason to mess with it in a vehicle not designed to run on E85, much less a Model A.

Not saying it can't be done properly, I just don't see why anyone would do it. There is nothing wrong with trying it to see what happens but if you had to make any modifications to make it run properly I cannot see any benefit.

Where I am at you can readily purchase E85 and know many people that have because of the price difference. Does not work unless it is a flex-fuel vehicle but even then fuel economy is down.
