Apparently the GA has a 3.63 final ratio whereas the Alero has a 3.05 final ratio.

I don't think that's right. The Aleros and GA 3.4L both had 3.05 FDR except for the Grand am GT which was 3.29. Maybe the 4 cylinder Aleros/Grand Ams had 3.63, but I don't think they were offered in the V6s.
Also, to OP it's not worth throwing in a 4T65E unless you're really pushing the 4T45E.... The time and money it costs isn't worth it unless necessary.
