RTS, I don't know where you're located, but I suggest that you find a bottle of Lucas Octane Booster and keep it handy. If you use the highest octane fuel you can find (91 or 93) and add a bottle of Lucas with each tank of fuel, your engine won't run it's best, but it will be much better than it will without the Lucas additive. I run a 1971 Cleveland motor that also runs on race fuel, but that's sometimes hard to find when you're 150 miles from the big city. The Lucas additive helps. Be sure to get the stuff in the red bottle. Each bottle is good for about 23 gallons and will bring the octane level to an acceptable level.
