Sounds like 4.10s or 4.56s. The 4.10s will put you at 2875rpm and the 4.56s at 3200rpm.

I don't know why you'd want to change them to 3.73's. The 4 valve motors love rpm and the 4.10's will allow you to see more rpm.

To tell for sure you have to put the rear in the air. Mark a spot on the driveshaft and have a buddy spin the rear wheel one complete turn while you count how many times the driveshaft goes around. A little over 4 turns =4.10s, I think you have 4.30s which is a perfect gear for a 97 cobra.

5th. Oxford is right, 4.30s would put you at 3015rpm. Dunno why I was thinking about 4.56s and not 4.30s...

They could be 4.10s. My car at 80mph turns at about 3k....at least when I bought them they were supposed to be 4.10s.
