That sounds typical of Ford running both systems for years. I worked with GM throughout the 80's and early 90's. Cadillac had a beefy 120 or 130 amp alternator and on more than one occasion they came in on fire. They would get so hot that they would ingite the inuslator plate between the diode stack. I'll be running a GM alternator on my engine due to the fact that I'm running a 500ci Caddy engine.
I think Todd got the info he needed (I hope) maybe he will give us an update and let us know how it worked out for him (hint, hint)
