I had the battery wired straight to the battery through a switch on the dash so I could control that piece.

Don't know what that means. What is the output amps of your current alternetor? Do you have an ammeter in the dash, or a voltmemter? A 90 amp alternator has worked fine for me with cars who's fans pull 25-30 amps, with an MSD and the headlights on. At idle at 850 rpm. If you put the oversized (underdrive) pulley on the alternator, put the factory one back on. The crank and water pump pulleys should be fine.
