Dwell is the amount of time expressed in degrees of distributor cam rotation that the points remain closed. The points open time vs points closed time(dwell) is a 1/3--2/3 ratio. Using an 8 cylinder engine as an example: 360 degrees of cam lobe rotation to fire all cylinders divided by 8 = 45 degrees of rotation allowed for each cylinder. 2/3 of 45 = 30 degrees of dwell for that engine. 6 cylinder: 360 / 6 = 60 X 2/3 = 40 degrees dwell. 4 cylinder: 360 / 4 = 90 X 2/3 = 60 degrees dwell. Now that I have given the math lesson for this evening, just set the points using a clean feeler gauge with the point rubbing block on the high point of the cam lobe and forget about dwell on the low speed engines. I had to dig into my OLD automechanics lesson plans to remember that lesson. Getting the adjustments JUST RIGHT is a lot of fun and gives a person much satisfaction when done.
