Trac-Lok question

How easy should it be to turn a wheel with the trans in park with both wheels off the ground (resulting in the other wheel turning backwards)? I used my Techwrench, and it read a max torque of between 75 & 80 ft/lb when turning the wheel.

On the subject of differentials, how much of a mileage decrease is usually seen when going from 3.27's to 3.73's? I'm probably going to look for a Mark diff in my local junkyards, and not sure what gears I should put in it when I do; I have 3.27's now. Funny thing with my car, is back when I had 3.08's, I actually got better mileage doing 80 than 65.
