Distributor changes

Thanks Mattax, that was very clear. For the 32 degrees at 2800 mechanical, I guess how that 32 is applied will depend on the build, right? This 360 mag will have a cam that isn't lopey, but somewhat aggressive I'm told (I'll see if can get the specs from the builder).

Let's see if I understood you. So, as a first approximation, I have the FBO limiter plate and spring kit. Many posts I've read say throw out the heavy stock spring and put a light one in it's place. The kit comes with gold (strong), silver (medium) and black (light) springs. Good guestimate of which I might try first? Then the limiter plate slots appear to limit travel of the weight pins in both directions, not just at one end of the slot, but both, so keeps more initial timing and limits total under acceleration. Good guestimate of a first slot to try? Say I choose 16 degree slot, and the springs allow the full 16 degrees at 2800 rpm, then I add 16 by advancing the dizzy at that rpm. As you say idle is what it is after that's done, I usually set my idle at 800-900 rpm. Then I do the vacuum method and figure out any vacuum can adjustment based on vacuum to get me to 50 degrees. Correct?
