Has anyone put a Ford(sorry) 3G alternator on their trucks/cars? From what I have read they are 130-200 amps from the factory. They have an internal fan,small and big cases,internally regulated.I have done a cs130 on my 72.

If you want more than the CS130 why not use a CS144? If you want more than a CS144 you can upgrade them to 250amp.
