front ride height concern

Murray said
This is normal. When you jack up the front of the car and relax the suspension, the tires are pulled inward. When you then set the front end back on the ground the tires do not allow the now inward set of the wheels to return to their normal position, the car is now higher. Driving the car a short distance or bouncing the car up and down in place should return the car to it's normal height.

Exactly, that perfectly explains why bouncing the front end of the car won't settle the car to ride height. Bouncing on the front of the car will settle the suspension, but it won't move the tires on the ground (unless you have a really slippery floor). You MUST roll the car to get it to settle to its true ride height once you've raised the wheels off the ground. If all you do is bounce on the front end, the first time you roll the car more than a couple feet it'll settle again.

Get the FSM and set the t bars tension correctly through the ride height measurement procedure. If you still have issues then worn bushings or non torqued pin bolts are causing it likely. Your K-frame pin tubes might also be an issue. This opinion is based on a pure stock setup.

Be aware the ride height settings effects overall alignment!

Stock ride height and alignment specs are listed here. Remember, all of this information is for bias ply's, and is not what you want if you run radials.

If you run radials, refer to the skosh chart for your alignment. You should run lower than factory height as well for improved suspension geometry, but if you're running stock torsion bars that's not really an option.
