Not quite sure how these spring work in a distributor. I have an original 69 350 distributor. I just replaced the spring because the advance was sticking. I put the head springs gold in. I get total advance by 2200 rpms and my total advance is still only 26. That is 11 initial setting and 15 at 2200 rpm. Do change the springs to lighter spring?
Total advance is not determined by the springs, only the point at which the mechanical advance begins.
There is a pin with a bushing on the bottom side of the plate with the weights. You can experiment with a thinner bushing, or no bushing, to increase the total mechanical advance.
The easiest way to remove the bushing without risk of dropping it is to pull the distributor and drive the pin out of the drive gear, supporting the drive gear on a padded block. Slide the shaft up and out, remove your weights and clean them up by rubbing the bottom side on a sheet of wet/dry sandpaper until smooth. Remove the bushing or replace the bushing on the advance limiter pin, then reassemble.

You can try to pull the bushing with the distributor in place, but I've tried both methods and it's faster to pull the distributor. If you have 90 degree needlenose you might be able to do it with the distributor installed, just don't drop the brass bushing into the distributor.

I am considering purchasing a Mallory Distributor. I have a lot of money wrapped up in this 455 and I want to do it right. I tried replacing the stock points with a Crane Cam electronic ignition converter and a fire ball coil. Not sure if I would have to replace the coil again with the Mallory any ideas?
