I would like the 4:30...
2 wheel drive 3:73.. very towable..
the 4:30 would allow a higher gear going up hill.. less rpms
engine is fine at 4,000 rpm's.. but body, sound, vibrations..
my opinion
The 4:30 will not allow less rpms going up a hill.
If climbing a hill requires x horsepower then the the engine will have to turn y rpm to make that horsepower.
Thus same rpm regardless of the rear end ratio provided you have a transmission that will allow the required rpm. The newer 6 and 8 speed transmissions do this very well.
There is nothing wrong with using 6 th gear with a 4:30 and 5th gear with the 3:73. The final gear ratio to the rear wheels will be very close.
Rear end Gearing does not make more power.
^^^^^ at least someone gets it!!! :B
