E-85 in a stroker

Has anyone set up their stroker to run E-85 instead of premium gas?
What I have read indicates a lot of knocking with 87 octain RUG in many strokers. Given the higher octaine of E-85, I am wondering want can be done to take advantage of the fuel??

Yes Yes Yes..I was also curious as E-85 is sold 3 minutes from my house...
Benefits, helping the enviorment..I'm a tread lightly type guy. High compression, allows for more aggressive tune = more power...cheaper but less mileage which would suck in our small tanks. Not sold everywhere...biger injectors, pump & possibly new fuel lines needed?

Sorry to burst your bubble, but ethanol has a lower energy density than gasoline, so despite the higher octane, you will not be able to gain back enough power via raised compression to match the power lost to the fuel switch. Unless you go forced induction and then swap to E-85 (E-85 is GREAT for F/I because of its resistance to detonation), you will never achieve the same power output with E-85 as you would have with gasoline, even with raised compression.
Sorry to be the bearer of bad news!

Correct. I wasn't clear. I was thinking high compression...12 maybe even 13's. Thus the need for either race gas or E85.
