ALL good replies and i thank you. I'll try to respond to them all here. First, i cannot package a different alternator without major changes. (time) The current pulley ratio puts the alt rpm at it's critical limit...i already did maximize the pulley ratio/custom. I will check out Snyder...THANKS! I was looking at the XS series and specifically the 3400 but now I'm realizing most of these 'good' batteries will require a new charger...even the 12V's So, now I'm leaning towards a single 16V and removing the alt from the car! Then metering the specific circuits prudently.
