My 302 H.O. w/T-5 trans has 2.73s in it. I can definitely say they are too high. I think I'm going to change to 3.55, possibly 3.73, for better acceleration and autocross.

Check out this website. It's great. [url]www.smokemup.com

You can calculate the speeds at each rpm using different rear ends.
