Should be fine AM, particularly with the msa ratios. If not, you know where the fuel screw is:)

yup, your 4HE1T torque curve should be very happy...:)

Don't forget when you change diff ratios you not only effect high range, but low range as well.
Also 235/85x16 are nominally 32", 255/85x16 are 33.1", 285/75x16 are 32.8".
Be careful when playing with ratios, as you might end up with your rev range too low at cruising speed. I think with std diffs and your gearbox ratio choice will be right in the sweet spot. The 4bd1 has its sweet spot at around the 2500rpm mark.
