Not a race engine? So you shift at what... 6500 rpms?

Maybe you should try 4.11-4.30:1

4.56 might be too low.

I have 33's on the back of my truck, and my motor is 6500 rpm max.
I had 4.56 in my Ford 9" to start with, and it was TOO LOW.

I got 4.11's in it now, and they are perfect for what I do. ( street / strip )
Of course, I have a hella-torquey bigblock up front, so I can pull a taller gear with ease.
