It would likely make more power/torque without damaging the engine so long as it was richened up quite a bit.
As someone else mentioned, the extra ethanol will likely ruin much of the fuel system unless replaced with different hoses/components.
In a hot-rod weekend car, I would consider it if I lived somewhere it was more readily available. It doesn't make sense for me here though, as E85 is harder to find than ethanol free gas.
