Also, how were the temps taken? If with a laser from Harbor Freight, they are meaningless as that is just surface temp (if even accurate). You need a proper pyrometer for taking temps and then you need to do it right away after making an auto-x run or road course lap. I can tell you right now that with that little amount of negative camber, as soon as you auto-x the car, you will chunk or destroy the outside of your tires if you are going fast at all. For auto-x'ing, foxbodies typically need -3* OR MORE of negative camber (for radial tires, bias ply slicks need less), all the caster they can get, and a bit of toe out. I.E., you should get C/C plates installed before your first auto-x.
For street driving, with most street tires, I like to start the fronts at 36 psi and the rears at 32 psi. I've just always liked how that felt.
