I belive av fuel doesn't make as much power as pump gas, but it should be ethanol free and leaded, which is nice.

Idealy I would want to run pump gasoline, and If I required a higher octane, I would try a COP swap, ignition advance, and run e85. I would also consider running 93 with a leaded octane booster. (Or I could polish the combustion chamber and the piston tops to help prevent detonation, but this is irrelevant, because if you can run 13.1:1 on 89, I'm sure you can run 13.5:1 on 92/93.)
