Kevin, after I get my 6 speed installed and gears in the axle, I think the engine and suspension are probably next in line, if you wanna try your specs on an allignment in my car, I'm more than happy too, you've driven my car (albeit when it was misfiring) in stock form, and I will let you drive it again with the 6 speed and my planned suspension underneath it, so if you wanna try it with a stock allignment, B-Body.net specs, and your specs, I'm willing. We should probably look around for a shop around here that would be willing to let us do that without paying too much additional cash to do so.
For those of you who don't know, Kevin and I go to school together. From the looks of the cars I see on campus at regular times, we are members of a very limited group of students driving 91-96 B-Bodies in the school, Kevins very respectable 93 L05 9C1 which is a very clean car, and my 96 LT1 9C1, which needs a bit of TLC, but is a good car.
AS it stands right now though, I've got 3 exams and a paper to get through this week then C-Term is finally done and I can get under my car to put the T56 in, if I can get my clutch here in time.
I think your best bet would be try progressively more and more until you figure out what is right for the bushings you have installed, I guess that different suspension setups would call for tweaked versions of the same allignment in that respect, while not drastically different, there would be certain differences due to less or more deflection while the car is in motion.
