Von,
Here's something that may help you.............
It was fairly common to convert 6 volt cars to use an 8 volt system, back in the '50s. First, you'll need an 8 volt battery. Western Auto used to sell a special regulator for this conversion, but I could usually adjust most regulators so they'd put out about 9-9.4 volts.
(I saw an 8 volt battery at Tractor Supply Company a while back, so 8 volt batteries are apparently still being made)
I've probably converted 20 grove tractors, some MOPARS, Fords, and a few others, from 6 to 8 volt systems; they really spin and start a lot better. You don't have to touch the starters.
The lights will burn brighter....and bulbs may not last quite as long, and the instruments on the dash may be off, just a little. But, if the wiring is in good shape I've never had a problem.
