Heavy Duty Alternator

I don't like the denso's much either. An engine I bought for my car had one, sat in a junkyard for less than 6 months and that baby was seized. I don't want to use the big heavy beast either but I'm probably going to go with a GM 12si or CS-121 or 130 alternator as they are decent pieces. I'll be making some brackets for one of those alts.

I have the amp gauge bypass...no stock dash anyway...and my headlights have relays that are powered from the starter relay (where is where the alternator power goes now) and I still have dimming. My engine idles solidly at 800rpm. (its a 360 with magnum heads) My dash voltmeter shows roughly 12v at idle with the lights on and about 14.3 (which is what it should be) at any point above idle.
