i'm building a 504 for my f100 daily driver. its going to idle nasty and not make vacuum at idle. I'm wonder about running a pro billet msd with no vacuum on it. How will it run as a street driver?

A properly dialed in distributor with mechanical advance only, will be as good as it gets if you don't have sufficient vacuum to effectively operate the vacuum pod.
You can also find a belt driven vacuum pump, like the one's they used on the old 6.9L IHI diesels to help supply vacuum.

Yes, the MSD distributors come with an assortment of weights, springs and stop bushings that with just a little bit of fine tuning, you can get very good results. It's not bad at all.

A vacuum advance is for part throttle, mid to low RPM cruising. It is used basically for less fuel consumption.
