The taller the gear (lower number) the better it will hold up. So 5.13 and 30in tires will not hold up as well as 3.91 and 26in tires, even though the overall ratio may be the same. Do you want to spend thousands, so it will never break, or rebuild it every several years? Coming out of the water, one tire can bite before the other, and burn up a clutch style posi. If street driven, a locker may be best, but they can cause noise.
A glide has a 1:1 hi gear as do all trannys except OD trannys of course.
112-115 mph with 28" tall slicks using 4.10 gears at about 6000 rpm. You can do the math from there. 114 mph / 6 = 19 mph per 1000 rpm. so 120 mph = 6300 rpm 114 mph x 4.10 = 467.4 /4.56 = 102.5 mph @ 6000 rpm etc
