Vacuum advance

Note the above testing procedures shown in posts 67-69 for dialling in vac adv will produce exactly the same results whether the VA was connected to ported or man vacuum. It makes no difference. Man vac cleans up the idle & tip in, ported doesn't operate at idle.

Maybe. But you should also note that you live in a completely different country and are advising someone on the other side of the globe. Australia had different cars, engines and tunes as American cars. You need to think about that. Your assertion that GM used manifold vacuum a lot is incorrect on this side of the world. There were very few car that did that here and I cannot think of one Chrysler product that did. Kevin has a very mild build and will benefit 100% from ported manifold vacuum.

And here's the beauty of it. It's his car. He can do it however he wants to. He can even change it up if he so desires. I think we all get your point. You prefer manifold vacuum. But your assertion that they will both yield the same results incorrect.
