I have a gauge for that

Here is a table with 34" tires and the different gear ratios when in OD on a 60e.
If you drive at 75mph, with 3.73s you about 1900rpm, with 4.10s its about 2100 and 4.56 its about 2350. Not much difference and well worth it.
Code:
RPM 3.73 4.10 4.56 500 19 18 16 600 23 21 19 700 27 25 22 800 31 28 25 900 35 32 29 1000 39 35 32 1100 43 39 35 1200 46 42 38 1300 50 46 41 1400 54 49 44 1500 58 53 48 1600 62 56 51 1700 66 60 54 1800 70 63 57 1900 74 67 60 2000 77 70 63 2100 81 74 67 2200 85 78 70 2300 89 81 73 2400 93 85 76 2500 97 88 79 2600 101 92 82 2700 105 95 86 2800 108 99 89 2900 112 102 92 3000 116 106 95

I agree with atomic that you will be just fine with the 4.56s even at highway speeds. A 34" tire is a very large one. Keep in mind this will also reduce strain on your transmission and you will stay in vacuum longer saving you gas. If you can't bring yourself to do 4.56 then 4.30s do exist.

I have a trans go shift kit and corvette servo sitting in my truck. Just haven't felt like messing with it yet.

4.56s will be fine with 28x12 slicks...the truck is still heavy and needs to get up and moving quicker
