A 130Amp alternator is worth it if you have Underdrive pullies or any extra electrical components(Amps, Head unit, etc). I would go find out how much it would be to install the gears and converter in your area. I had a AOD and it was really slow because of the tranny. A stall converter and gears will really wake that car up.
