I was running 91 in the states but on a RON its a 95 out here, most of the states thats all you can get, some places do hold the 93 but that,s with ethanol which is 98 out here.
I have been reading the thread and to be honest Matt to even think of Av Gas these days is a dream, why would you ever think of it unless you are running for pink slips and want the total out of the car it was something we did in the 80s same as we mixed Benzine in with the fuel, I think I even have my old beakers and fuel weights if you want to try it.But be prepared re graph dizz cooler plugs ext ext.
Have it set correctly on a good tune its really not that hard if you have all your specs of you compression and cam spec,s but if its out of your hands send it to Easy 10,s at St Marys he will get it going like a scolded cat.
