Use or don't use vacuum advance on distributor???????????????????

First off he isn't my tuner. He is a friend of mine helping me out and we are tuning it together. I have been told by multiple people that a 750 holley is plenty good. Wrong for my intake how? Elaborate for me please.
Do you realize how much of this back and forth could have been avoided if you had been up front with your problem and answer the questions that were asked of you? There are some incredibly smart people (not me, I'm not that smart) here that are trying to help. Try listening. If you have a stock 5.9 Magnum with only a dual plane intake (Performer?), that is not the right carb.

Can you run that carb on the street? Yes you can. Will it be the best carb you can run on the street? Well, how's it working out for you so far?

I'm out.
