- - Alternator ?? (https://67-72chevytrucks.com/vboard/showthread.php?t=43165)

I was told when I bought my '83 it had an '86 350 block. My alt went out last week and I need a new one. My question is will the alt be the same for the 83 and 86?? If I need to I can take a pick and post it here. :D

I was checking autozone's website and it seemed the alt amperage for each year was different. :confused:

It shouldnt matter Izzy...You can always upgrade teh alt to a higher amperage. Mine is a 140+. Just get the same style..

Is yours a one wire or does it use the plug??

fiveeightchevy,

I would go with the higher amperage alt. But like LOHRTBT said check to see if you have the wire or the plug.

:burnout:

It has a plug in the back that looks like a spark plug boot and a dual wire connector on top. :D

ok...so it uses both.. THat means yours is probably not a self exciter. The one wires are self exciting. You can tell them this when you get a new one. :)

Checker sales 100 amp life-time warranty alternators for less then $100. I traded in my stock alternator awhile back and got the 100amp. It hasnt given me any problems and we hooked it up to my fathers machine at the dealership and it put out the power as stated. It really starts pumping the juice at just off idle (1500 rpm or so). Do you run alot of accessories? Do you have an electric pump for your bag setup? The more power you run at idle the dimmer your lights will get. Im gonna buy a overdrive pulley for my alternator, except I cant remember where I got the price from. I have to recheck the mfg's. If it works out the way id like Ill be sure to post and let you guys know about the pulley.
Check and see if AZ offers something similar to the 100amp im talking about.

I do have an engine driven comp and it puts out the same juice as a normal ac comp. I should be fine as this old azz alt didn't have any probs turning it. :D
I'm gonna take the rusty pos off tomorrow and go get a new one. :D

If you had a electric pump you might want to go to a bigger alternator, but since yours is engine driven, it doesnt matter.

COME ON!! Get you a supa dope chrome unit!!

Maybe he plans to spray paint this life-time one chrome :)

Izzy call Fritz at Midwest Electrical 972-680-8322 I got my 120 amp chrome from him same day for $118. tell him Steve and Brandon from Southern Bowties told you about him.
