Rear gears are 5.13
I have changed instant center from 48" out and 10" up
to 59" forward and 9" up with no noticeable difference in results.
I have had the bottom 4 link bars "nose up" trying to achieve as high an
instant center as possible. I am starting to think maybe trying to adjust
the bottom 4 link bars so they point down slightly in the front to see if that will help.
Also I have ordered a set of slicks. When I took the DOT tires off I noticed 3 perfect muddy water stripes inside the wheel tubs!! directly above the grooves in those DOT tires.
I really appreciate every ones advice.

I think you will find that the slicks will fix 90% of the problem in my experience big street tires aren't as good as even little drag slicks.
One other thing to keep in mind is engine coolant temperature you need it to be consistent if you want the 60' & ET's consistent.
You might also want to get someone to video record your launches, paint a white stripe on the side wall and pay attention to the inital hit, if you can see the line going around it's hooking, it the line is a blurr then it's not! If the tires spin on the inital hit your 60' and in some cases your reaction times will be inconsistent.
