I can tell you that with my Javelin I had a 3 speed auto with a 2.87 rear end and a 304 and it was pretty boring and slow. I swapped in a AW4 and 3.54 rear end which made the final drive ratio 2.79 in overdrive. The car has the best of both worlds now. It really moves out nice and I can run it on the highway at 75 mph without killing the engine with rpm's. It is the best thing that I ever did to the car.
