Here is where I'm at just for comparison:
19 initial / 37 total. 1 degree per pound of boost retard.
383 / 8.5 static / aluminum heads 2.05/1.60 / 1:1 for 12 lbs on a 6-71 large bore / Demon 750s all on 111 octane. One step colder plugs.
My Demons love initial advance, more so than a comparable Holley.
Give the crew some more specifics and I'll bet you get some answers.
