I really don't know, would have to look it up. But in general a flathead wants the advance all in by 2000 to 2400 range and a maximum advance of somewhere around 20 to 24 degrees. Initial advance originally was at 4 degrees I believe. With a more modern distributor that has both centrifugal and vacuum advance/retard you can run a bit more total advance.

"You probably want about 4 degrees static and enough centrifugal to take it up to about 20, and the curve should be fast, starting in right off idle and getting done before 2,000. This is of course a starting point for experimentation--every engine has its own tastes."
