well, for one, you have to adjust the air to fuel mixture...so in a carburated car, you have to change the jets in the carb (holley carb), and in a fuel injected car, you would have to change the injectors, to run the added amount of fuel. that is the easy part.

my understanding is that in order to run alcohol, every component, and basically everything that the alcohol will touch, has to be stainless steel because the alcohol causes corrosion of lesser metals.

with my fuel system in the mirada, i dont know how much isnt stainless already, but it wouldnt be worth my trouble to check...however, on my buddys sebring, he is redoing everything anyway, so while hes at it, hes using all high grade stuff so that the ability is there to run alcohol.

and if im not mistaken, thats it...
