Okay, that makes sense. Mine is a 1973 with 3 wire alternator. I think the last time I bought an alternator it may have been a sad little 60 amp.
383 man, does that mean alternators with field wires may excite sooner? Possibly at lower rpm?

The have enough magnatism in the rotor and stator that they self excite once they start turning but I am not sure how fast it has to turn to start charging. I would think idle speed is enough as I have not heard anyone complain about them not charging right after starting. Many racers like the one wire alt as its less wires and cleaner looking. But once the excite themselfs they just get stronger right away and start charging good. Course then the internal regulator takes control of output. Ron

there are 2 sizes of alt pulleys, make sure you have the smaller one (I forget the dimentions right now). You might see what dia crank pulley you have tho subbing one in is a pain cuz you need the right offset unless you have a good stash but I would see what you currently have
