I'm trying to go with a 100amp one wire alternator for my 1975 f250 4x4 with a stock 360fe. All of the alternators I have tried are to deep and the back of the alt hits the cylinder head. I need some direction on how to get this done. I've dug through posts and called a retailer or two and have not come up with anything better than going down to a OEM size 75 amp. I will be running a dump trailer and a pop-camper both with trailer brakes. Jim from Centech who is currently building me a new wiring harness almost insists on a 100amp to power everything at once. Some direction would be most appreciated.

 

Go with a 3G swap instead, you use a Ford alt that you can source out of a junkyard and it is rated 90 and 130 amps

There are other threads all over the Dent and Bump side forums and even the Bulldog forums, just search

 

Good info!

 

Well that was easy! Thanks for the link. Got a new 3g alt at NAPA waiting on me and Jim will wire my harness up to plug and play! Thanks again for the tip.

 

Thank you
