What you want the car to do coming out of the hole is weight transfer to the rear. If you have adjustable shocks in the front. You want them set full soft on rebound, and full stiff on compression. What this does is let the front come up quicker, and keeps it from settling down too soon. And a stiff springs helps too.
On the Z. You want to have the compression full stiff. This keeps it from squating, and changing camber. Stiffer springs here too.
When I used to drag raced my 440 Dart. I ran 90/10 shocks in the front, and 50/50 shocks in the rear. The front would pop up like right now.
