Vance:
Thanks for the info. I may try the four 36 degree total advance settings
again this weekend and see what happens. I haven't reached a point where I
heard pinging.

        As a data point for your consideration, my '74 with a stock
dizzy uses 10BTDC as the base, and adds 26 degrees of advance for 36
degrees total. No pinging ever with 9.6:1 compression, mild street cam,
pocket ported head, stock exhaust and Zenith carbs with B1AR needles.

Bruce and List:


I just finished testing the 123ignition electronic distributor and I
love
it!  The switchable settings allowed me to test each setting to identify
the
best selection.  There are four settings for each maximum advance
setting.
I started with setting 4 which is 10 degr. Advance at 500-1000 rpm, 16
at
2000 rpm and 30 max degree advance at 4500 rpm. I progressed up each
curve
(5,6,7 etc. - all for 30 degr. Max advance) and found that the #6
setting
worked the best.  Keep in mind is the best is determined without a dyno
and
only by my driving around, listening, and sensing performance.  I didn't
get
any pinging so I tried the next max advance settings for 33 degree
advance
but didn't notice performance improvements.  #6 seemed the best to me so
there it is.  I am curious is 30 degree max advance at 4500 rpm is
enough???
But it seemed to run better than the 33 or 36 max advance settings.
