Stick with the FOMOCO. No fooling around that way. Unless you ask for it specially built, alternators are internally regulated. Called a diode group which is easily replaced if trouble develops.

I had one done for me at 80 amps. Reason being, my 427 fought the starter when it was warm and really drained the battery....even a big one.

After a little tinkering and a new battery, the problem went away, but I still liked the quick recharge on the battery.

BTW Alternator should put out 13.8 volts not 14+ and you won't have much luck finding a single wire alternator. Remember how an alternator works. The big wire is the output to the battery and there has to be a current TO the alternator in order for it to work. that's the "exciter" wire, which excites or creates the magnetic field and makes it generate current when the rotor spins.

The least number of wires is generally going to be 3, but they go to the alternnator as a group, so it's not messy looking. Some people tape them and some use that split wire covering for neatness.
