Nothing in this area that I am aware of. My comp is around 10.5 so it is bearable with booster and 93. There is a place in the burg that sells non ethanol 87 for 5 a gallon though!
Find your local dirt track. They may not sell it but I bet you they know who will. The circle K by ours even sells good old turbo blue leaded. They won't let you put it in a vehicle tank but you can fill gas cans and transfer tanks. Even barrels.
