Vacuum port for vacuum advance

Is this a good spot, or should I have it lower ?

Re: Vacuum port for vacuum advance

Pretty sure that's the one Holley intended to be used for that purpose.

It's "ported" vacuum; there's no vacuum there until the throttle is somewhat open; not always "The Best" solution, but, a good starting point.

Try it and see what happens.

You like to live on the edge I see... rubber death-trap fuel lines. Not me.
