    6 volt or 12 volt??


    I have a 36 ford truck. Hard starting etc. I want to upgrade the ingnition system etc. I can go with a 12volt MSD or Mallory system and use a volt-a-drop etc. for the guages etc. or stay with a 6 volt system. I talked to a guy in Texas at thepitstop.com. They are associated with Pertronix and will have a breakerless 6 volt system for sale in a couple of months in the $200-300 range. I am just wondering if anyone has converted a stock flathead to 12 volts and if that is the way to go??

    Car Year, Make, Model: '51 Chevy Fleetline and a Ratrod project

    12 volts is good, most people convert, if you stay 6v, all is good but bulbs have to be 6v to be bright enough, if you can get a 6v electronic dizzy, go for it, you can get 6-12v converters ( there about $80 ) to hook any radio or anything to the 6v system, but if you don't like your battery to say " Farm And Tractor " on the top, you don't want 6v. I'm keeping my '51 Chevy 6v, and I have seen a few others remain 6v. 6v vehicles do crank slower than 12v vehicles, might start a little harder, might not, my '51 Chevy fires up in 3 cranks normally, but it might be harder for your Flathead, depends on your tune up and timing accuracy with 6v a lot, my points are ajusted correctly, I'm shure that helps me out.
