E-85 Questions.

I would like to hear your thoughts on running and building a race motor for E-85?

13-1 Static Cr. With E.F.I.

Is it better than 110? Should I just bite the bullet and go full alky? what about E-85 blends? whats its octane rating? This car will get fuel in the S.F. Bay area, and hopefully some longer than 1/4 mile trips. Will I be able to find fuell?

Is this even worth thinking about?

Thanks for the time and advice.
