i would say 342's if your about 1700 to 1800 rpm's at 70 mph

Get yourself some 4.10s and you will be happy. Trust me, they really wake these cars up.
Preferably w/ a 9" rear-end.
BTW> I know that doesn't answer your question, but whatever your stock gears are... they are too weak for your power level.
