I've never tried this, but if you don't want to go with dual batteries but need a little more juice, I have been told another improvement over the 6-volt system is to use an 8-volt battery. Again, I'm just repeating what I've been told, but apparently that is not enough to blow bulbs or hurt anything, but it offers a little more power. Just a thought.

I have a '52 Chrysler Hemi with 6V that has performed flawlessly for almost 4 years with these steps taken: Two 6V Optima batteries connected in parallel. (The two fit neatly in the battery tray.) A rebuilt starter motor. The original generator recored to be an alternator by Don's Genernator in OR. Should anyone use Don, for originality, be sure to say you want the generator to look original, with all original tags left on, and not to put his sticker in sight.
