To answer the original post, Light bulbs are the main thing to consider, Many have said they have converted and are happy with it. The main reason seems to be the brighter lights which will just burn out faster, and a somewhat faster starter. 6-volt starters seem to work very well, and even though they crank slower than converting to 8 or 12 volts, the 6-volt starter in my car does pretty well. I would think that if one is to convert, I would go with 12-volts, negative ground, and an alternator. At least then you would have something more standard. I think going with 8-volts is asking for problems down the road. That's just my opinion.
