Vacuum advance

@Mattax what curve should I be looking for?
In the end, probably a curve similar to the one in the Chrysler built MP distributors.
Going from your cam and engine, initial will probably be strongest somewhere between 14 to 18*.
So something in the gray shaded areas would be a good place to end up.

What I think you'll find is another matter. LOL. That's why I'm pushing you to measure it. I've got a couple of guesses but no way I'm risking your machine with my guesses. wink-gif.gif
Sure I'll plot the results as long as you give me the rpm for each measurement.
