In 69 ,38° total was the standard tunnel wedges, tunnel ports, medium risers.and super Cobra Jets.My deal is most original distributors only had 10° degree advance plates = 20° .That way the manufacture didn't spend any more to preceisly control advance by changing springs and weights .18 ° inital is a lot for the starter to crank against 18+20=38.In 69 I had my distrib for my 406 reworked for more advance and less inital all headed for 38°.I do not know how much is built into "this "Mallory distrib. But as a benifit of the recent purchase of a Mallory HyFire VI.It has a programable auto start retard ( anything below 500rpm). Now try to figure a "Vari-Cam " into the mix.I still have that in a box up in the attic.
