Read the "Bigger Alternator thread". Everything you seek is there :mg:
A junk yard AD244 from an early suburban with the HO alternator is the answer.

Where to get an Ad244 besides a junk yard? I need to get a new alt more powerful than stock one, how can i test the stoc one? how many amps should it push? I want something that i can just bolt on plug and play.. I plan on buying a new one not rebuilt or anything.

Summit Racing sells new 200 amp AD244 alternators made by Tuff Stuff for $200-$250 depending on type of coating (chrome, black thermal, or natural aluminum). I have one in my 05 ZR2. They are direct bolt in, however you will need a 1" longer belt due to the increased case size.

Don't forget the NAPA HO series. It worked very well. Details in the bigger alternator thread.

Not really cheaper. NAPAonline shows it for $254 , my cost locally is $232 right now. Ten of them available.

Check locally. That way you have their help if you need service.

Yes, that is the same one. You don't need to swap pulleys with this one and the factory harness plugs right in with no modifications needed. The price is better than anyone else when you consider that is has a black heat dispersent coating to reduce temps, requires no adapters, no pulley changes, benches well over 200 amps, and backed by Summit's excellent customer service. The only part you need is a 1" longer belt.

Just go into your local parts store and ask for one that is one inch longer than stock.

Probably. As long as it will deliver enough amperage at a given speed to meet or exceed the loads sensed.
