I got a wild hair to run my car at the "day of the drags" this year. Changed out to 373 gears and changed my carb out (needed one anyway) The carb has no vacuum ports anywhere on it 700 holley. My vacuum advance isnt hooked up right now and I dont know weather to just plug it or what any help is appreciated
Thats weird the carb has no vacuum port? I hooked my vac advance up to the one on the pas side of the carb. Also a holley, 600 though.
In my opinion, for the street, find a good source of vacuum on the manifold and use the vacuum advance. If you are racing the vacuum advance won't be seen since you will be flogging it at WOT and the vacuum advance would be inactive any way. There is a great article listed on the main board relating to ported versus non-ported vacuum for a vacuum advance. You might do a search for that thread and give it a read.
Ya there are no ports at all it runs fine just hesitates for a 1/4 of a sec off the line. It just buggs me knowing it should be hooked up somewhere or plugged or unplugged I dont know
