To be a bit more accurate, the NVG3550 has a 0.78 ratio for 5th and most
brands of 33" tires are actually around 32.8" when new. So, with a 4.56
diff, Troy's I6 would be turning 2550 rpm at 70 mph. Right now, with his
4.11 diff, it should turn 2300 rpm @ 70 mph. If he up-sizes to 35s,
he'll turn 2400 with 4.56 or 2570 with 4.88 (70 mph).

Just be sure the Significant Other is not given the opportunity to compare
your 6 inches with your Lift Kit's 4, she'll just get confused.
