I don't find any dwell specs given so maybe like torque specs, that wasn't much of a thing then.
Publications of the day have differing specs on point gap with the SM saying .015 while a later Packard publication says .017. Packard and other publications give a wider range with .013 being at the bottom end of that range. Possibly the cam has worn a bit resulting in your car running better at the narrower gap. I would guess where you leave the final setting depends on how well the car runs.
