That should make for a great combination, right?They are 4.11
Sure, 4:56 would be better, but with the 1st gear ratio, I would think that it won't be bad at all.
I have pulled a mixer truck across town with my shop truck, twice! It's an LY6/6L90 with 4:10s and stock size tires. It will be neat to hear your impression of it.
