A long long time ago in the fifties and maybe earlier, my father would always carry a thin worn silver dime. Said set the points to that and you will get home. Actually worked for me once on my 58 Delray which was a step below the Biscayne, one year only. 6cyl did get 100mph until valve float took over and took out a piston..017 has been working fine for me. I usually end up on the lower side of the dwell range which I like as it leaves a little room for rubbing block wear. But it depends on yout technique for measuring the gap with a feeler gage. Some will go for a light/loose touch with the feeler gage blade and others go for a little snugger fit between the points. It doesn’t take much effort to move the points arm with the blade if not real careful and consistent.
Yep, what we used to say in high school 1987, i had Pontiacs then so did not know if Mopar was different, this is my first MoparWhatever thickness a matchbook cover is. ( a tip given to me 50 years ago )
Thanks for the tip, ill go .017”.017 has been working fine for me. I usually end up on the lower side of the dwell range which I like as it leaves a little room for rubbing block wear.

That is what I thought and my Engineer buddy sent some Chilton pages showing.017.017 has been working fine for me.

Single pretty sure, never seen a dual pointQuestion......single or dual point distributor? The dual point gap should be: 0.016" - 0.017" each . The single point gap should be 0.020". AFTER setting the point gap, then set the timing @ 15° BTDC (+/- depending on fuel, carb, cam, gear ratio, etc). Just my opinion of course.

Same tip I got from my dad about 50 years ago also.Whatever thickness a matchbook cover is. ( a tip given to me 50 years ago )
I have some NOS, not cheap.Same tip I got from my dad about 50 years ago also.
Do they have matchbooks anymore?
