I am pretty sure that the guy who did the on-board welder found in some old cabs a 120 amp alternator. If thoose would bolt onto a chevy motor that would be good, do a search for the On-board welder, he went into dicussion on what to look for.
The above reply was close.
Those where externally regulated chrysler.
I don't know what year eng. your working on so...........
Find an alt. off a TBI cop car or cab about the same year. If the brackets look different get them too.
The cool thing is most (in the 90's) cop cars (gm) are 140a.[img]/wwwthreads_images/icons/cool.gif[/img]
I don't have a junkyard answer. I will say the Chevy Police cars in the early 90's used what know as the Delco CS 144 series alternators with as much as 140 amps. The usual alternator used with 350 TBI engines were the CS 130 series alternators with as much as 105 amps. The alternator bracket for a CS 130 alternator will hold a CS 144 alternator, and vise / versa.
With Chevy 350's there is lots of interchangability. I'd never dare say what years of 350's accessory parts would fit what other years of Chevy 350's. There are so many changes over the years that my chances of getting the correct junkyard parts to work would not be good.
