I am looking for a calculator or a "rule of thumb" for determining how much static pressure I should have in the pressure plate.

The long story:
Several years ago when building the drive line I had flywheel resurfaced, the clutch rebuilt and the Hayes pressure plate resurfaced at a shop in KC.
I changed to weaker springs in the Borg & Beck style 10.5 inch pressure plate.
That was a mistake. Now it is slipping.
Only have 300 miles on the car so far but I recently opened it up and the clutch was slipping so I need to change springs.

A few more specs, 410 posi, T56, 295 tires with about a maximum of 540 lbs. of torque.

Not wanting to buy another setup just trying to determine what springs I should have in the pressure plate.
Got any recommendations?
