Here is one of the best definitive articles on vacuum advance. I converted my 66 428FE from a non vacuum MSD back to a Ford dizzy with a Pertronix ignition and vacuum advance. Unless you are running your car at WOT, you should run vacuum as this article so perfectly explains. You will improve cooling at idle, drivability and plug fouling. Take your information from a power train engineer and not from a backyard hobbyist. Rick

Rick, this was an awesome thread! I have the MSD pro billet dist with no vacuum advance at all. I guess my thinking was same as the carb, Mechanical, no vac secondary's. Vac anything is for sissies with regular cars, not Hot-rods. I guess I may have to re-think this whole thing, especially since my car sees no track time at all, just aggressive street driving. Again, thanks for posting this very informative information.
