Phillip, I'm with the other guys -- and a couple of other items to add. The H generator will do 14 or more volts unregulated. You simply need to change the regulator to make it work at 12. To Hugh's point, the stock generator won't go much north of 20 amps (thus the 20 +/- on the ammeter). Even small, cheap alternators will produce 45 amps - lots more extra power to charge the battery, even when the lights are on all the time. If you have a coil/distributor ignition, and are going to 12V; you'll need a dropping resistor to keep the feed to the existing coil at 6V. If you're hot to rebuild something, rebuild that old starter motor. Easily turning bearings and good brushes make it spin lots easier; meaning the 6V system can turn the engine as fast as any 12V conversion. The fat cables and clean connections need to be there, like James says; but the crux of any starting system is the starter motor - so concentrate on it. As for the low buck horsepower: that's the holy grail of every hotrodder. Talk to most of 'em and you might hear that the biggest bang for the buck is a nitrous oxide bottle. You basically double the percentage of oxygen in the air -- result is bigger explosions. Downside is rapid heat increases in the head. Short of that, the cheap way to help any engine is to make it easier to inhale cold, clean air and exhale the burnt gas. All depends on how original you want to keep it, what and where you intend to use the torque or horsepower - and your taste for cubic dollars.

The Day Tractor Lovers Dream About - by Angus Crawford. The day started at five o'clock on the morning of Friday, the January 29, 1999. My father, my sister, my uncle, my cousin and myself all climbed into my uncle's Toyota van. It was six thirty in the morning and we had a long day ahead. We traveled for six and a half hours to our destination - a little country town with a population of no more then one hundred and fifty people (57 of them being children under the age of thirteen). We arrived hoping to meet up with a man we knew had over one
