5 groove internal regulated alternator upgrade.
 

When I did my motor swap awhile back I chose to go with the serpentine style belt the engine was set up with. I bought a new 72 alternator and just put the newer style pulley on it. I worked fine for a season but now the pulley just keeps coming loose. I've done a little research about unhooking the regulator and looping 2 sets of the wires. I'm wondering who has done it and what alternator you've used. I've also seen some people add a resistor inline to the alternator, is that necessary for the swap I'm talking about. I believe it's a 10 or 12si I'm looking for, perhaps from a mid 80's camaro?

Thanks in advance. I haven't messed with it in awhile and can't find some of the info I found before.

Just do a search in the Electrical section of the forum for Alternator Upgrade and you should find more info and pics that you care to read or look at. It's very easy to just rewire the alternator and charge wiresand then remove all the old wiring and external voltage regulator plug and the EVR itself. Good luck!
