S.C. Express will become famous soon enough

I would not bother with the 3.92's. Go 4.10's maybe, but me personally I would go with the 4.56 gears. If you plan to tow a lot it will help the whole truck last longer.
3.55 to 3.92 is only 2-300 rpms difference. These trucks should have had 4.10's standard imo.
