Ridetech built Goodguys 69 Camaro ?

If that is your chosen ride height (which there is nothing wrong with) the front is fine. The 5.2 stroke shock compresses at 11.2, so you'll have approx 4.5" of compression travel at the wheel. More than enough.
On the rear, you'll have about 2.75" of compression travel.

If you want the car lower, go to the 4.1 shock.
