The first gear may not be deep enough for the trans you have combined with your tire height.

I put a T10 with 3.23 gears in a car with 255/60r15's, and my first gear was close to yours. It was a bit hard to get it rolling compared to where it should of been. In my opinion. It originally had a 4 speed saginaw with roughly a 3.0 first gear.

I would drive it with the 4.10's for a start, and then make changes.
