high amp alternator?

I want a good one wire setup that can run an electric fan, electric fuel pump, and electric water pump on the street.......with headlights and a radio as well. I have an external regulator, but would prefer one with a built in regulator. Who sells a good 100 - 120 amp setup for a small block chrysler. Is there any sort of bracket that I need to run one of this sort? And, since my battery is in the trunk can I run the one wire to the starter relay?

thanks,
Daryl
