I too have tried most of the combos listed. My current set up has "A" body SS springs(002-003). I run Rancho 9 ways set on 9. NO SNUBBER. I also run the Centerforce "11" clutch assembly. A833 18 spline. From personal experience, SOMETHING has to slip, unless you plan on breaking parts. My car is set up to slip the slicks about 10 feet at launch. Radials with a stick car don't work. I run Hoosers (29" x12"). My 60' times are around 1.54-1.60, depending on track conditions, but my car is a street car that I take to the track sometimes. It's not an all out race car. Also, my car weighs 3726 without me in it. With my 200+ pounds, it's a load to get moving. My rear gears are 4.56 Dana's. Hope this helps you get pointed in the right direction.
