distributor advance tuning
I'm new here and hope someone can help me. I am working with a '77 electronic distributor and want to modify it for more centrifugal advance. I am set to 12 degrees initial and the centrifugal tops out at 10 degrees more at 2000 rpm. I find that I can get lighter springs to make the advance come in quicker. Can I open up the advance slots to allow more centrifugal advance? I assume that this is the way its done. I have another distibutor that is a '74 electronic. I think this distributor may have more centrifugal advance built in but I have not been able to find specs on it. The distributor number is 3656763. Is there a source online to find distributor advance specs for a given year of distibutor? Thanks to all. Bill
