Good points on good connections for powers and grouonds Don. I do use crimp connecters at times but prefer to do solder connections, thats ingrained in me from my years working in a dealership. Warranty doesnt approve of butt connecters and while they work most of the time they do create problems at times. What I was going to mention though is using relay switched power for distributers/ingnition systems. Pull the power from batterg instead of starter and run thru a relay switched by ignition switch. Will give better power to ignitiin system as power from starter will be drawn down during star up. This will work with all igntion systems including 6V. Not a new concept as it has been discussed here before. If the igintion system had its own power circuit that would be best. And yes the 52 gmc had been converted over to neg grd. We aslo converted it to 12 V. So deve its your call now! I'd say you've got lots of input. One last thing on the stock distributer, check it out carefully. Make sure the cam lobes aren't worn, vac advance is free and tight, gov wieghts and springs are good and move freely. Basicly a worn out dist assy creats problems.
