i have a 60's 351w with 2bbl carb. it has 2 small vacuum ports, one in the front right (if you are staring at it) and one just in front of the choke. which one is for my vacuum advance?

ok found the solid answer. per ford, if its manual then use a timed port one that gains vacuum with throttle. if you have automatic thrn use a wide open full time port. many choose other routes but this is the design.
