Alternator, Regulator & E.C.U.

60 amp isolated field alternater, correct voltage regulator for it. I'm told the newer regulaters are electronic while they still look like the mechanical OEM. I dont know if they supply enough system voltage for electronic ignition to operate properly.
4 pin ignition module, 2 post/single circuit ballast resistor, electronic ignition distributor.
Done

That's exactly what I'm running! What I'm wondering is if it's worth the extra expense and installation time to change the voltage regulator from the electronic regulator that looks like the old electromechanical one to the '70 and later "flat pack" V.R., change the two pin to a four pin ballast, change from the four pin E.C.U. to a five pin controller and wire in the currently grounded field on the alternator. Any significant improvement in power, fuel efficiency, reliability or anything else? Still wondering.... Thanks.
