Back before I cracked the motor open, I had 4.33's in the stock housing. I was real happy with them. Unfortunately I didn't have them long enough to get it to a track. Once I had done the cam swap, I went with the 9" and am now running a 4.57 ratio. At the strip, I cross the traps right around 6430 in 4th. My recommendation would be to go with all the gear you can IF you plan to stay NA.
