Comp Engineering Shocks question

I have competition engineering shocks on the front and rear of my Barracuda. I have the fronts set @ 90/10 and the rears 50/50...this, with a pinion snubber and VERY worn out leaf springs that are completely flat. For some reason this works (see sig for times), but I'm saving up for a complete Caltrac setup to get those 60' times in the mid 1.4's....or at least that's the plan.
