I have never done a change over on A Chevrolet but I have done them on model a Fords and from my experience they’re not really worth it. I believe that the main reason that people do this it’s probably because they want to have brighter lights , better starting and they can have accessories.
Since the brightness of lights are measured I lumens and not volts, it doesn’t really matter. A 6V and 12v lights of the same lumens have the same brightness besides 6V LED lights are popular now and are a lot brighter. Most accessories are now computer based so can run on 5V so …, if you keep the 6V starter it will spin faster so that might be a plus but if you need that, something else might need to be looked at.
And then there’s the cost…. New starter, new 12V lights…. Front, rear…., new coil, labor…. + etc….
Wiring should be fine….. higher voltage less current.
Many are done, I see a demand but don’t really know why.,,,, 6V seemed to work fine when they were first built…,
