I appreciate everyone's input. I'm more concerned about reliability than I am originality. I understand the higher amp alternators don't produce rated output amperage under all conditions. But they are capable of charging at maximum rated amps if needed. The stock ammeter is designed for +/-45 amps. Police cars had an amp gauge rated for +/-60 amps. If modifying things by eliminating the amp gauge to accommodate a higher amp alternator makes sense, then maybe it makes sense to simplify the charging system by going to a single wire alternator and eliminating the voltage regulator. Internally regulated Mopar style alternators are available. Does anyone have any experience with this?
