running low lead kinda helps defeat the purpose. we ran av gas back in the 70s. 112 or 115 dont remember but it also had a high lead content which our heads at the time needed.ran a 12.5 .1 327 tunnelrammed with a 4 speed. . ran that same engine on the street and strip. and i drove it hard. sold the car in 89 and it ran as strong as when i first built it,

Honestly, if you're going to buy something other than "Pump Gas" (which is available in some areas as Sunoco 110 or 112 octane) You're far better off buying and using racing gasoline of your octane choice. The quality is better and you always know what you're getting . . Thus your "Tune Up" is consistent . .

Even the LL contains 1.2 to 2 grams TEL per gallon. As far as running it, with 11 to 1 you will be quite safe as long as you jet it correctly. And avgas has very good vaporization characteristics which is a good thing, if you get some do a test. Find a piece of metal to put some on along with some pump gas and if you have some racing gas. See which one vaporizes first, and which leave deposits that don't vaporize. Any that don't will be very difficult for the engine to burn. Depending on what you run currently for fuel you may need to jet up one or two jet sizes.
