Depends on your set up. What carbs are you running?guy's have not been on lately trying to get the car together for the muscle car nationals then they canceled it crazy times anyway does any one know where the vacuum advance connects on my 409 duel quad 62 impala?
You need a copy of a factory assembly manual then. Has lots of great information that a repair manual won't have but you should really have both. My factory assembly manual has more information in it for my wagon then the repair manual covers with images/drawings.everything is stock on the car bought it as a basket case trying to keep it as stock as possible
post a picture of the manual you have? There are a number of different ones for each year.i have the factory manual no mention of vacuum advance that i can see
