If I couldn't out run them with the 2.73's I still wasn't able to with the 3.73's, it just redlined quicker. It'd have to shift to 3rd to get to 60 mph and 110 or so is all it would do in 4th.
I used the 3:31 ratio in my '89s that I've had as a matter of fact I have a set in my garage that I didn't get to install in my last '89 GT. I also have 3 1/2" straight stainless tips that I never installed on the '89 LX. I should probably list them for sale lol
