The Stovebolt Site Forums The Shop Area The Electrical Bay Whats the biggest generator?

Whats the biggest 12 volt Chevy generator, (amps that is) that can be readily bolted into an Advance Design truck?

I know that the stock 6 volt A-D generators were about 40 amps; and regulated at about 36 amps. And regarding pulley size, the drive ratio of engine RPM to generator spin was 1.83 (2400rpm generator to 1300rpm engine). {I mention this cause the ol'tractor restoration guys warned me about swappin' generators with different pulley sizes, seems it really screws up the cut-in-out voltages!}

But I was just pondering a switch to 12 volt and thought I remembered a rumor that some late 1950's early 60's BIG Task Force etc Chevy trucks (2 ton plus)MAY have approached 50+ amps?

If there is a 50+ amp Chevy generator, and If anybody knows the specific model please let me know so I can price it out.

Finally, I know the alternator swap is the most efficent way to go, but I was just wondering/diddling about big old generators.

Thanks

one question is ---whatcha gonna do with all them amps? do ya need 'em? at any rate, a good electrical shop can rebuild the gen. and install bigger stator windings--hench--more amps. for a more h.d. regulator, leece-neville makes one that can handle 130 amps o.k. (feel yer back pocket getting lighter?) anyhow, old g.m. generators were used in starter packs years ago--plenty of poop for starting cars with dead batteries.

koolkar,
Can the re-builder use the old 6 volt generator housing and insert the bigger amp coils? Or do I need to get a 12volt junk yard generator?

What I am going to do with all the amps. Well... that kinda falls into the realm of "whatta my gonna' do with a 50 year old, 8 foot tall, 2-ton truck".

i like the pic--tis a thing of beauty---and one hell of alot of work!! o.k., down to work, if yer gonna keep the 6v system the stock gen is fine--as wel as the standard capacity 12v---if all yer doin' is what you say. i THINK the electrical shop can rebuild the 6v gen to 12 volts--but don't see the need for mongonmous amperage in the application you described. best advise i can give is go as close to stock specs. as possible---why fry batteries before their time? 50 or so amps. should do all you want in my opinion, especially since you ain't got a/c power windows etc. and while yer at the shop, inquire about 12v blower motor--might save you some pain later. hey--how about a picture of this monster? i REALLY enjoy checking out other guys stuff! hope i helped some
