Thought I'd get a few opinions on what would be the best rear gear. I have 3.08's now when I install my Novi I will be going with a shorter gear but I am in between to choices, 3.55's or 3.73's. I have seen guys at the track running 3.73's and it seems like 1st gear can become a hassle because of the T-5’s 3.33 1st gear. Even with 3.73’s at 75 mph in 5th gear revs will only be 2500 rpms. I am wondering if the higher gear would be better for a car with stock heads and cam. But if I do a gear swap I want to feel a noticeable difference. What are you guys running with similar set ups?
