The overbuilt (90A or 100A) 10SI alternators tend to be weak at idle. Still, one should be enough in your case. A CS-130 alternator would be more suitable.
There's no pissing contest. We're talking about connecting fans that draw maybe 40A to the alternator and 666WMD is talking about wiring some load that will draw 700A. They're not the same things. Comparing the wiring needs of one to the other is a completely retarded thing to do. Besides, auto electricians and alternator builders fix the car electrical systems which were designed by electrical engineers so I'm not bowing to the so called expert opinion in that 2nd hand information arguement.

If you so desired, you could also first run this new wire to a stud type terminal block and then to the alternator. This terminal stud would give you a convenient place to connect the relays for electric fans and a fuel pump. This stud could be on the firewall or inner fender close to where the relays will go, which will make a neater wiring job.
The method of just connecting the fans to the alternator is a short cut to avoid changing the wiring in the car. It does work as long as the load is no higher than the capabilities of the original wiring. In most cases for older GM cars, the main alternator wire is a 10 guage wire which means you could attach about 60A of load to the alternator.
