Most of the Altenators you see forsale on line or in catalogs are junk. I went through 2 new ones before I went and had my original one rebuilt. No problems since rebuild.
I would pay the extra for the rebuild or a real deal GM altenator. I would also replace the voltage regulator if it's an external type. They are cheap and when they start to go they can be a real pain.
Did you ever check the neg bat cable ground to the frame as I sugested in an earlier reply?

Hi again, new or rebuilt is a matter of debate, when my alternator failed I went to Auto-zone, that was 02-05-2000 it cost $ 36.03, it lasted untill 09-17 2006, when it had a bearing noise, they gave me a free replacement, with another 99 year warranty. The regulator is inside the alternator on our cars and it's set to put out about 13.8 volts. Is that what your asking? PG

No problem Nick, I'm sure your exited about playing with your new Vette, and it's nice that your dad is involved in trying to help, in my opion it's best to replace everything as stock, once you get the car to run properly than you can modify it the way you want. As far as the altenator goes it will put out enough juice to keep the battery charged for the next restart. As Schoon and others have mentioned, the ground wire, the neg side of the battery may have corrosion which will keep the altenator from charging, so you'll have to disconnect the leads and clean them properly so that you have good connections. there are lots of seperate ground connections on our cars and you will have to clean and reconnect them one at a time. You say that you inherited thr car ( How lucky can you get ) but if the car sat for a long time the points may be pitted so you should replace them, thats a cheep fix. The 74 does not have a lot of horse power so don't expect to blow to doors of the first Viper you pull up to.
Is your car auto or stick? In either case you have a netural safty switch, if it's not adjused properly you cannot get the car to start.
Have the new battery checked sometimes they are just bad from new. Then check the fan belt it could be loose. Check that the wire to the altenortor is tight.
We havs covered a lot, but this is where I would start, if this does not solve the problem, let me know and we'll go deeper into it. Hpoe this helps. PG
