Re: distributor cam
Longer dwell on the "B" cam gives hotter spark.

Re: distributor cam
The B cam has about 9 degrees more dwell and 4 distinct lines, while the A cam has 8 distinct lines where the rubbing block enters and leaves the lobes.

Re: distributor cam
Tom, that is a great photo and explanation of the two cams. I knew the B had more dwell and was the better choice but I did not know the visual differences. Thanks for posting this.
