I would start looking at better shocks to control the rear better .
I would agree although I went a foot breakin 1.33 60 ft. w/slicks on 5-way Rancho's a while back but now run Shiloh's Vikings and have been a 1.34 60 ft pulling the ft up 2'on QTP's street tires. Better shock controll made my car come alive and hooks on the street now and my slider boxes are biased towards the rear and never bottom out in either direction...............

If you locate the shocks to be more straight up than angled it may help even more cos it made a BIG difference on my Dart........
