Last year I upgraded my alternator from the stock unit to a powermaster 140amp alternator. My old alternator is fine and all, I just wanted more amperage to power the excessive draw from my stereo setup. Here is the deal. My brother drives a 1997 cavalier and his alternator crapped out on him. He wants to buy my old alternator off of me to put in his car. I was wondering if an alt from a 305 would fit on a 4cyl 2.2. I don't think it will however I figure I would ask before I told him no it won't work without knowing for sure.

 

It would not work very well.

 

If you don't mind me asking what model alternator did you buy for your transam. I have an 82 transam with a 305 and bought a powermaster 47294 model but it is too small for my brackets and I'm not quite sure what to do about it.
Did you run into a similar problem?

Thanks and sorry for asking something somewhat unrelated to your post.
