Ethanol in the 7?
So yeah... When I finally get her running, I wanna keep GreenPeace off my back...
I'm not going campaigning or picketing, or anything, but a high flow 3 way cat, precisely tuned carb, and maybe some cleaner burning fuel will go into the car...
What are the disadvantage of ethanol, aside from eating away rubber?
The carb was freshly rebuilt about two years ago, so any seals are not old 1985 Rubber... Fuel lines aren't too hard to change...
What else?

It won't eat your rubber and bad as gasoline does. Certain components of the gasoline, especially the benzene will do it. Ethanol (denatured alchol) is NOT going to eat the rubber UNLESS..the rubber is pre-1950's rubber, which was nature rubber. All rubber today is sinthetically made and will put up with a lot and not break down. Methonal will harm the rubber, but that is not ethanol.
I wish people would not believe myths without looking into it.
Here in Minnesota, gas has 10%ethanol added, no ill effects have ever occured to my fuel lines as a result of it......

If you run pure ethanol you'll have to change your jets, as about twice the fuel will have to flow. You'll empty a tank faster. Also, ethanol is 100 octane (in fact that is what defines octane), so any questions about too-high octane will have to be answered.
Henry Fords cars all ran on alcohol originally. Even the manufactured cars had a lever on the carb for many years to switch between gas and alcohol. Ford preferred alcohol because of petrols propensity to blow up, but petrol became cheaper and came to dominate.
In Brazil 50% of vehicles run on alcohol. And in the midwest petrol typically has 10% added ethanol.
Low cost ethanol would be a good fuel (high cost ethanol is commonly used in racing, like the indy 500, because drivers rebelled against the horrible fiery crashes of petrol). Even in the midwest, were there's plenty of corn, ethanol is marginally more expensive than petrol. But a scientist in florida has developed an enzymatic process for creating ethanol from forest slash.

In minnesota and some midwest states sell E85(85%ethanol 15%gasoline). Its intended for FFV's(Flex fuel vehicles) Do a search on the web and you find several manufacturers make EFI systems that can use any combination of gasoline up to 85%ethanol. Ethanol will reduce mpg, increase power, and produce cleaner emissions. NO, I am not a ethanol salesman! 
I re-jetted my old mikuni carb to use E85 and made a Garonteed 10% more power overall(better yet if higher compression could be changed on the rotors). It was cool because I could go back and forth from gas to E85 and get the power and MPG when I needed it.
Gas has 114,000btu's/gallon
ethanol 60,000btu's/gallon
E85 81,000btu's/gallon
Going by that will tell you how bad your MPG will be. Re-jetting, you will need about 30% more fuel with E85 and 40-45%more with pure ethanol as a starting point.
