Hey everyone, if you have seen my other dist post u know im about to buy one. I have always thought that vacuum advance is better than mechanical for street cars but I dont really have any reason since i dont know too much about em. Can someone give me some advice? If mechanical advance is better than the vacuum then I guess I should go with MSD dist bc it is cheaper also. But if vacuum advance is a must or something I should really go for then i need to go for the mallory. Help please!

I wanted a vac. advance distributor in the worst kinda way. I also wanted it to be a MSD. I called them up and asked about it. The guy said yes I have one on my 5.0 for testing, give us a while to test it and maybe we will market them. Time marches on and 6 months later I call back and am told that it was scraped. Sooooo I buy one that is mechanical only. I get good performance and EXCELLENT MPG. The vac. adv. would surely get me a little more efficiency but I make due without it. On the old forum this was discussed at length. John

It would be a shame to have passed the test but to have missed the lesson.

I think you'll be wasting your money! For the street it'll be hard to beat a stock Duraspark or Petronix. Get an Accell blueprinted series, they come with extra mechanical advance springs and adjustable vacuum diaphram. Cheap and hard to beart! Ask camachinist!

Sorry to disagree, I have had stock, then Accell Bluepint (both with Pertronix) and now an MSD. The Accell is a waste of money, their fantastic rebuild is little better than throwing on an Accell cap (that cracked the rotor contact off) and the extra springs and adjustable vacuum advance that was never used, a stock rebuild from an auto-parts store is hardly any worse. In my case I didn't want vacuum advance in the end and the MSD has worked out fantastic. The curving is simplicity itself and the car's response just improved magnificently.

I got the pertronix designed for the hipo dual point distributors...it doesn't use the vacuum advance at all, and it works fine for me.
