super stock spring windup question

I've got the 8 3/4 rear sitting in the perches with about 3 degrees down on the trans end of the driveshaft and about 4 degrees up on the diff end of the driveshaft giving me the one degree difference I think I'm looking for. How much spring windup should I expect and adjust for on a "mostly' street driven 440, 727, 4.10:1 gears?
