VetteVet - Thank you very much for the info.

gmachinz - I am running a 320 amp one wire. 180 amps at idle. 100 amps was not enough for my purposes. Currently, I run 4 ga from alternator to battery, and 2 ga from batteries to the inverter. None of the original 12 ga is in use. I have fuel injection, fuel pump, A/C, and dual cooling fans to run. Plus I have a dual battery system and a 2000W inverter, and a 5,000 BTU window mounted A/C in my camper top. The alternator will provide enough power through the inverter to run the 5000 BTU A/C, while still charging the dual batteries, and running all the other electrical in the Blazer. This doesn't even consider my winch. So yeah, I've tried a 100 amp alternator, and it was not enough.
