A 130 amp does nicely....they are specially made for Ambulances and Police Units...(they have LOTS of lights,,so go figure) Cost is around 150.00 rebuilt with exchange, Some Autos require special mounting brackets and/or Voltage regulators. You will need to exchange another Alt to complete the cord charge or pay for the cord charge.

They have some serious (200amp) jobs. You have to do a little bit of mods to get it to fit, but well worth it.

Yeah, the 94-95 mustang alternator. You'll have to grind the bracket down a bit and swap pulleys and ditch the external regular. Do a search for "3G alternator swap" or check this page out:

you could just add another 100 amp alt possibly, another thought is using your P/S pump to run the plow or adding a belt driven hydraulic pump with joystick control and solenoid valves running your up/down, left/right, straight plow/vee-mode... now your talking 
Also 2 1000 CCA batteries is mandatory for electric motor plow rigs

Hey, that (http://www.bcbroncos.com/3ginstall.pdf) was cool!
Do you know if there is one for the late 80's corvette (the ugly one) alternator?
I have a 130 amp internal regulator unit that has one pos stud, and three wires, one red and two are brown and all three are next to each other and I looked at the wiring diagrams for it and am unable to tell which brown one goes to what!

Not sure on GM. I think they are internally regulated. I think a haynes/clitons should show the wiring..

Instead of huge CCA batteries that are not kept full all the time, try some deep cycle marine batteries instead. They will last much longer with all the charge / discharge cycles while plowing.
You always have some lots that you are running to slow to keep the batteries up and running the plow hoist almost nonstop. No alternator will keep up with the plow / lights drain while plowing them. The deep cycle will not cook from this like the mega CCA batteries will.

Those 200 amp alternators should do the trick!
How about running two 200 amp alternators?
One primarily hooked up to each 1000 cca battery?
You can also change the drive belt ratio so they pull faster rpm's at lower engine speeds!
