E-85 on a 360

E85 is a great way to go for power though, you can tune a lot more out of it if you do it right. The octane rating and fact that you use extra fuel is nice because you get the cooling effect of the fuel and the detonation resistance. You don't need higher compression to run it, but you can't go wrong with bumping it up some, though you will lose the ability to run plain old gas in a pinch if you go too crazy. Though with a carb I guess you pretty much can only tune for one kind of fuel at a time anyway.
