I hear ya!
But from my experiences I have always chose to keep the front down. My Falcon ran 8.70's with low 1.20 sixty foot off the trans-brake at 5500. NO WHEELIE BARS! First time out I nearly drug the rear bumper with low 1.30 sixties. Added positive pinion angle on the adjustable ladder bars and dropped the front considerably. Idunno, I am no expert but it worked for me. The Kaase headed 514 came on REAL strong on the big end and got a little hairy at times and I even ran 32x14 Goodyears at first. Was really hard to get them to stick so I went with Hoosiers. BIG difference! Less time on the burnout (Goodyears needed a Top Fuel burnout to get sticky).. I really needed a Anti-rollbar for the horrible sag in the right rear. I had a crap load of preload on the right coilover too. Still would lift 6-8 inches after playing with the pinion angle.
