Argo1,

I run Union 76 110 leaded racing gas in both of my motors and have never had a problem. The book for the big block in the 1969 Torino Cobra said use nothing less than 105 octane and I have never had a problem with it and it is now 34 years old. I don't drive it a lot as it is getting old and is registered as a historic vehicle and I can't get parts any more short of going to Jack Rousch or some racing shop. My 351 stroker in the replica has 10:1 compression and I also run that gas in it and have since I built the car in 1996. I also run it at about a half mix when I am out just crusing as the racing gas is so darned expensive, but as Snake said, be sure to run the motor often. I run mine every two weeks during the Winter until they are well warmed up.
