Re: posi rear end gears
That is a very nice looking square body right there! If you really do have 2.73 out back and a standard 700r, 1st gear off the line is probably OK, but 2nd gear must be a let down ( I'm thinking WOT here ).
If you don't want to change your current mileage/driving characteristics, don't change the gear ratio.
If you want to change the way your truck gets down the road and/or increase the fun factor stop light to stop light, change the gear ratio.
I would first make sure you know what you have currently. Determine that for certain then decide what you want to do with respect to the ratio.
