Sometimes you see that if the cranking pressure is really low. Then, you kinda have to play it by ear. I've seen some take 22 degrees initial.....but that's probably about "as far" as I'd go, UNLESS I decided to lock out the timing, which I've never done. IMO, that's a step best left for race only, or almost race only engines.
Yeah, it does have low cranking pressure. When I first got it there was a Mopar tach drive distributor in it set up to go to max advance as soon as the car started.
