There is something about seeing a GM alternator on a Mopar that makes me want to They do work though. I got a 120 amp Denso on my car and it works well.
I always found this funny because Denso is owned partially by Toyota. I've never been sure why installing a USA made GM part (many Mopars have GM Saginaw P/S pumps and steering columns) is bad, but a Japanese part is ok on an old Mopar? We use 10SI/12SI Delcos on everything, street rods, muscle cars, 40's/50's cars in 12V conversions, farm tractors, etc. Install and forgetaboutit. If you use a denso, for God's sake get one with an internal regulator, the mopar regulator (especially the ones you get from parts stores anymore) are garbage.

If you don't "update" the rest of your electrical system using the basic principles discussed on Mad Electrics website, you are risking some serious problems by running a higher output alternator with all your additional electrical load.
I ended up using an upgraded (rewound w/ heavy duty bridge rectifier & regulator) AC Delco CS 144. The comes in Escalades and some full-sized pick-ups etc. It essencially bolts right in with a simple adaptor. It puts out 115+ amps at idle & over 200 amps above a fast idle.
However, the more difficult & time consuming part of the complete electrical system upgrade job, is to wire the car to be able to safely distribute and protect the wiring system.
