The tech archive states that the MP electronic ignition dist. is set up to bring the timing all in by 2400 rpm. If I wanted 32 degrees total with an idle speed of 750 rpm (in gear), I would set my initial timing to 10 degrees BTDC, correct? I don't want to have to rev the car and make a bunch of noise to reset the timing. Am I off base here? Here is the formula I used to calculate the initial:

32 degrees total / 2400 rpm = .01333

.01333 X 750 rpm = 10 degrees

EDIT - I realize that this equation will only work if the dist "curve" is straight.

(1) use vac gauge method to find the initial your eng wants/needs. (2) w that figure in hand shorten slots to get 35 (sb) 36-38 (bb) w vac adv unhooked plugged & magnums may like only 31 & some low comp 383 may want in the 40's (3) toss the heavy thick spring w the long loop on one end & start w one of Mr gasket springs or a MP one & keep the other OE light spring & want just enough tension to stay just under the pinging point at WOT up thru the gears on your hottest/driest day or to come in full right at peak torque if on a dyno. Then hookup vac adv & w 3/32" allen wrench stay just under the pinging point at part throttle (high vacuum) at or above an rpm where the mech springs/slots are maxed out (steady cruise on the highway). CW makes the slope start earlier (less in hg) & the AMOUNT is fixed unless you want to file both sides of the notch in the arm (more) or solder strips of feeler gauge under it to limit it's travel (less)
