My alternator is shot, anyone know what amp. alt. it should take? Got an '87 V-8, 305 w/ AC and A.T. Someone let me know & Thanks - George :???:

The specs for 78 call for a 61 amp when optional A/C is ordered. But most rebuilts are higher now anyway. Talk to the parts guy and see what he has close to 100 amp with the same body, not the bigger ones.
Another option is to go to the local rebuilder and have him rebuild yours with higher output. This might be cheaper since you cut out the middle man.
OEM GM units have the amp rating stamped into the case. once they get rebuilt, that stamping becomes irrelevant, since you don't know what pieces are inside. I wasn't happy with my original unit, so I acquired one from a similar year Monte Carlo with a 4.3 V6 and it was 94 amp.Hi BillyJack, Is that the original engine for a 94amp? I have the OEM V-8 and the Alt. shows no clue of the amp. requirement. - George :???:
