The 2.94's won't make much difference. How much highway driving do you do? I went from I went from a 2.76 to a 3.23 Sure Grip and didn't notice much difference. I am looking for a 3.55 or a 3.73. I wish I had saved the 904 lock up out of a 85 5th avenue I scrapped. Next to a overdrive that would be a cool addition to a 3.73 gear.
