Running E85 with 11:1 pistons in 289

[Hondo78]

Thanks, I had run pop ups in a Ford engine several years ago when we could buy Sunoco 112 in California. I see alcohol race series engines running 180 more Hp per 350 cubes running e85.
Is there any issues with letting the car sit through the winter with e85 or must it be drained and flushed?

Also do you buy the alcohol by the drum delivered? I see you can even buy it on Amazon.com for about $2 /Gal (I might need to replace the 16 gal tank with a 20 gallon)
