Identifying High Output Alternator

All the Delco alternators I've ever seen have the rated output stamped on the cover (around the circumference, not front or rear) along with some other stuff, like "Delco" IIRC, as well as part numbers.
If it's been rebuilt, many times this info is ground off.

Even if it has been rebuilt it could have been built to put out more amps.
True. I'm mainly talking about stuff in the wrecking yard. Alternators bought from Autozone, Checker, Schucks, Kragen, Pep Boys Etc., will oftentimes be found in wrecking yard vehicles, so it's common to come across new looking alternators with no idea what they actually are output-wise.
Good thing about many wrecking yard vehicles, if it isn't there for theft or accident, many times they will have little used replacement parts...since so many people spend money on replacing parts randomly to solve problems, the same vehicle they just wasted money on they end up giving to wrecking yards because they couldn't fix it.

How very true that is.

oh ya so basicly the only way to tell if its high output is to take it apart ? i know they make those kits to convert and off the shelf ones but what to look for ? i dont have a clue 
You could try to find one off of a commercial type GM vehicle, I don't know the part number or even the official name, but I was told they are large case GM altenators. That is what I have, rated at 100 amps. I guess the bigger case is designed to help handle more heat so the internals won't burn running near full bore.
