That is pretty low. I don't think I ever got mileage that low, even 
when 67AC140 was a 67AC110PG car. Is your timing right? You don't have 
it retarded to keep from pinging, do you? Is your vacuum advance 
working correctly? Do you think the carbs were rebuilt correctly? What 
jets do they have? Something seems wrong here. You should do better 
than this with an FC.
