Since distributors are the recent hot topic, here's my problem. It's a 57 or later NAPA (semi) rebuilt, installed 2 years or so ago, but much later I checked the dwell & found it under spec. Reset points, still well under the 26 degrees minimum specified. When I inquired here some time ago, was advised (by John "H" as I recall) that the Distributor cam is probably worn. Left it over the winter, did a recheck & discovered that if I accelerate the engine the dwell is also moving 2 or 3 degrees. Does that indicate that the advance plate is also defective? Are parts available for these distributors? I have a 55-56 distributor here, can I mic the 2 cams as a possible check, & also may have access to a 317 dist. to check. Are the cams the same? I'm sure some one is going to recommend an after market MSD or other unit, but, my car is licensed & insured (at a discount) on a stock collector plate. Obvious mods are not permitted, except safety items such as brakes & light improvements. I don't see any point in getting another NAPA (Canada) unit. What are my options? Any info appreciated, thanks
