Tom, like Jason said...get some good (boxed) lower control arms, the re-location brackets, drop the lca's down to lowest holes, a right side airbag for a little pre-load, a T/A rear cover and HD stud bolt kit, some HD (I used Moser) aftermarket axles, and the 10 bolt 7.5" rear will live---for AWHILE. 4.10's worked great for me w/my stick car, and a Vig. 3200 stall w/3.73's works very well w/the automatic cars....this, w/your cam, headers, and a good computer re-tune, and a set of M/T d.o.t. radial drags should put you very solidly into the 11's. Best wishes. WJ
