at the moment i have a 2.41 ratio in my monte carlo LS. i have found a couple g bodys with different gear ratios available for around $90.00 complete drum to drum. one is a 3.08 out of a 87 cutlass and one is a 3.23 posi in a 83 grand prix. would i notice a little difference in these or should i be looking for a 3.73 rear ?
