Ed it isn't about trashing a system that has stood the test of time for about 100 years, it's about finding a more efficient upgrade while still honoring the era, keeping the engine, and getting the most out of it. We know the points system works famously. I never rebuild an engine and start with HEI, I use a points distributor to set the timing, valves, carb, etc. then I go to HEI.
In fact, I was so adamant about making this upgrade 100% reversible without doing any damage to vintage parts, I caught all kinds of flack. I want to be able to remove the HEI plate, install points and condenser, remove a jumper and drive the truck home on points if I want to. Its all about choice.
When you see the difference for yourself, you will understand the transition better. The engine runs much stronger, more deliberate and more efficiently, burning leaner mixtures more completely. The GM HEI module is a mini computer that controls the dwell at all RPMs, making the timing absolutely perfect and not subject to mechanical parts that wear over time.
Nothing wrong with points at all. Keep them and enjoy your ride and the feeling that you rightfully should have knowing you didn't modify a vintage vehicle.
That attitude is not for everyone however. Some of us just want performance tweaks that are mild. VERY mild. NO V-8s, etc... in an AD. Just a little improvement to upgrade things to today's driving conditions. I do every engine I rebuild, every modification with the idea in mind that I am creating these things for a daily driver. If you get your vehicle out for an occasional parade or local car show, alot of them are not for you. No trash can here.. I will have on board my vehicles a brandy new set of points/condenser to get me home if my newfangled (1973) system fails me!
