I have an 89 GT vert AOD. After installing Flows and BBK h pipe, I really noticed loss of low end torque. Someone suggested changing the rear end gear to a 3.55. I guess right now it has a 2.73. I think I will make a change, but should I go 3.55, or 3.73? I don't do very much highway driving with this car. Much of my driving is around town, Not usually over 60 MPH. Any suggestions? Pros? Cons? Any idea about cost? I'm thinking somewhere around $500.00. Is that about right? Thanks, Howard
