Gasoline Octane Suggestions

KOZ45 said
I am getting ready to soon start my project car, Duster with a 440

What octane pump gas should I use when starting it up or even what octane should I run in the tank?

Any additives or stabilizer suggestions?

This is like telling the group you have teeth and asking what kinda tooth paste you should use... or going to the bar and asking for a beer; you want piss beer or craft beer? Details matter man...
