Points for 66 273 dual point

my 1967 dart / charger factory service manual shows point gap at .014"--.019" but i have found on the big blocks IF the points set flat to each other .015' will get you 42 degrees. my book calls out one set 27 degree to 31 degree. and both sets 36 degree to 40 degree total. DO NOT set gap less than .015. there is a tip. clamp the shaft tang in a vise. 2 or 3 lobes are higher than the others. rotate the housing slowly and set the points so a small feeler .015" falls down out of the points, on the highest lobes.
