Short answer is yes there is a ported vacuum connection on carbs before 67. I have a 62 383-2bbl, and a 62 413-4bbl both have it done in rubber hoses. 1960 413-4bbl has it with a hard steel line.
Not for distributor advance
Your not serious are you? So what is it for if not distributor? I don't know why you would trash a thread for kicks with mis-information, clearly you are wrong in your statement. But why? That 66 hemi of yours has ported for the distributor.
