If you already have SS springs, then you need stiffer shocks. They dampen the extension & compression of the suspension. I had Mopar auto drag shocks with SS springs and under certain conditions, they went into pretty bad wheel hop. I put Rancho 5-way (old version, new is 9-way) and problem was solved. The harder your car launches, the stiffer shocks you need.
60' times isn't all in suspension. A LOT can be found in converter and carb tuning as well. I recently sent my "good" converter to be freshened up & put my back-up in. I didn't realize how much different it was (looser) and I lost around .02 in 60' and .10-.15 in the 1/8 mile! I have run 1.47 60' times, 7.0's @ almost 95 mph on 9" slicks weighing 3,540 + lbs.
