my convertible has a 3.23. With the 400 4 spd it's a very acceptable gear for both acceleration and top end. My cammer has a 3.55. With the 4.1 1bbl OHC the gear is nice to get the car up to speed. But it tops out quicker and adds a few more revs. But it's not excessive. It's another very street-able ratio. I guess it all depends on how much gas you want to burn getting between points A to B.
