I will have to get a nice big optima battery of course 
Are there any bolt in alternators for our cars that make some extra amperage?? (duratec v6)Im soo glad to hear you ask about getting a new alt rather than someone asking so how many caps do it need?
First you'd be surprised that stock alts would proably handle the job fine...BUT i would still at least do the first option:
1) Well for one if you dont mind being out a car a day, you can get your alternator rewound and Im sure that would perfect fro your needs.
2) But if you want on a new alternator or dont want to give up the car
