My alternator just went out on my 92 bird with the 3.1. It is the newer small style alternator. I want to upgrade to one with more power. I know that the 350 Iroc had a 105 amp model available. Does anybody know of a more powerful factory one? How much power does mine make now? Thanks

 

if you have the smaller sized alternator, you are pushing 105.

 

Yours is a 105 amp alt. But i hada go from a 105 amp to a 140 amp one and i still frekin have charging problems lol. DONT BUY AUTOZONE unless you wana change your alt every 2 weeks like i did

 

Where did you get the 140 amp alternator. If from autozone, what kind of car was it out of?

 

So the smaller "new" alternators are also 105 amp? Cool, I didn't know that. (I have the older "large" 105 amp one.) I do know that from 82-84 the small alternator did 67 amps...
