Here is the latest setup from Mark that I found last week for a
customer:

Mark Pavidis - 777 settup

front 60w oil (70w if hot out)
1.4 piston
blue spring
inside hole in front tower
inside hole for shock on arm
22 caster block
Low A block
std sway bar
ride height front bones just above level
5000 diff oil
steering in rear hole in rack
droop depends on track slightly limited

Center
48 tooth spur
13 clutch bell
3 shoe clutch 1.0 springs
7000

Rear
35 w oil
std rear sway bar
2 deg anti squat
3 deg toe
hubs back
camber link long and in lower hole in tower
2nd to inside hole in tower
inside hole in arm for the shock
blue springs
bones level if bumpy just above level

This should help some. Try 20 grams in front of the rear bulkhead on the center line.
Let me know what you think of it.
