If it's an 8 3/4, keep that gear for weekends at the track. After racing, you can easily swap in a highway gear for driving during the week. That is what I used to do. I'd drive a 3.23 during the week and pop in my 4.56 to drive to the track.
That would be the way I would go. If you have 4.56 already the final drive would be the same. 4.56 gears are fun with the 4 Speed I miss that and will be keeping them with my auto. Not a daily driver though!!!
