Alternator reccomendations

Tell me your usage,the good ,bad and the ugly. Please give a more comlete description of your electrical system as well,including any upgrades,or if it's stock. I am seeking infomation that will help in selecting the correct alternator for my application. Will be a big block,stock wiring system (upgraded to heavier wire) ,but with headlight relays,and an amp gauge bypass. Probably a heavy demand for electricity with my car.Most likey a multispark ignition,home brew fuel injection, and hopefully a Classic air con system.

So I'm going to need a fair amount of amps...Might even upgrade to some sort of power door popper.
