Mechanical advance distributors question

[82 GT]

Ok, I think I see how this works now. So if I had more centrifical advance in the distributor then I wouldn't be able to get away with 16 degrees initial advance. In other words, if my dist. had 30 deg. centrifical advance then I could only have about 10 deg. initial advance.(roughly) in order to stay within the 38-40 deg. total advance picture.
I know some engines can take more than 40 degrees.
I'm assuming that the more centrifical advance you have, then the less initial advance you have to "play" with.
Does that about sum up the timing thing?


Yeah, I remember once you wrote a very informative thread about how to tune a car up with just a vacuum gauge. I'll have to see if I can look that up in the archives.

Thanks PKRWUD

P.S. I also think that you should change the title under your name
to "very knowledgeable member" or "engine guru" or something like that.
That "junior member" certainly does not fit you.

Thanks again!!
