I am going to be rebuilding my rear end in my cobra so I thought my as well throw some gears in at the same time. Well I was planing on doing 4.10s but I have heard that I should get 4.30s from some people.
So I wanted to get the good and bad from people who have 4.10s and 4.30s.

Thanks in advance for all your input!

how much power is the car making? What kind of car is it? Going from the stock 3.27's or 3.55's to 4.30's will be a very large jump and I wouldn't recommend it if the car has a power adder, the stock gears or 3.73's would be best.

Run it at the track as is, and make your decision based on the numbers you get. Take into account the tires you run on and off the track diameter wise and the overall use of the car.
