Need help with shock selection

[mrn2obelvedere]

The current setup is as follows:

Addco sway bars (1.125 front, 0.875 rear)
Magnum force tubular adjustable upper control arms
manual steering (will be switching back to power steering with a steering quickener at some point)
panhard bar in the rear
stock leaves (with addco front spring eye pivots/solid rear shackle bushings) and torsion bars (for now, I will upgrade these as money allows. I will likely use fiberglass leaves when I do upgrade the leaves)
I plan to add a cage and sub connectors, again, as money allows.

The engine is a 360 small block with aluminum heads, the trans is a 727 auto. I want to keep the car as light as possible for handling hence the small block.

My intent is to have a car that gets the maximum possible out of the torsion bar front/leaf spring rear suspensions. I will likely autocross the car, but only in the open class for fun (I'm not even dreaming of being competitive with modern cars).
