A lot of interesting experiences and opinions. Thanks.

A.S., I looked at the Powergen a few years back but you couldn't mount the fan on one, or at least you couldn't back then. From what I recall it was either the rpms or bearing issues, but I know for a fact that tech support said no fan.
As for the EJ Whitney alternator/generator, what do they cost? No prices on their website, so it's probably high. I can tell you I have 50 bucks wrapped up in the rebuilt '56 genny and a couple hours swapping out the front cover and trimming the mount ear off the back and sanding and buffing it out.

This isn't good if you have a lot of things in your car that require electricity...radio, heater fan, etc. It worked for me even driving at night. But that is about all I ever used that was requiring extra amps. Terry

Terry, When I looked and compared the internals between the 6 & 12 volt generators there wasn't anything obvious. However I remember seeing a part listing which showed distinct 12v and 6v field coils so I thought there must be a difference. But the housing are identical.
