Consider either making your own upper arms with more caster built in, or relocate your upper A arm brackets about 7/8" to the rear and use your stock arms.

Other things I like are
AFCO delrin A arm bushings I don't know if these have the side "washers" that a Global West bushing kit would have. You might be able to make some.
Stock car stock appearing coils, 5" OD X 9.5" tall. Use a threaded adjuster on top, cut it to fit your upper spring pocket taper.

I don't have a big block spring bar setup but the tuners like Guldstrand or Hotchkis would probably use a 650 front coil rate and a 175lb/in rear leaf rate. Stock is 325/110.

You can drop the front rate for a better ride but 550 is probably minimum unless you just cruse it. A lot depends on horsepower, tire size, and how agressive you want to drive it. Also, the lower you go with the ride height, the stiffer your springs have to be.

A small block Camaro is going to need a 1" solid bar up front and depending on rear spring rate, some kind of rear bar.

haha.. man i printed about 40 pages off your site and the guldstrand mod looks to be the way to go! im gonna give it a shot for sure..

what do you think about the afco upper a arms? i noticed they sell a 4bolt style ball joint to go with them which is supposed to raise the roll center.. at 45bucks a peice i thought id give them a try.. you think they would work ok with the GuldMod? the part number is ss101-100 and the ball joint is af20032-1..

i looked through smileys catalog today and didnt see the afco delrin bushings just solid steels that i was gonna hone out and press some delrin in.. ill do a little more research.. i did see they had the springs your talking about and the adjusters.. and i also agree with the spring rates.. whats your take on the afco shocks.. i noticed you could get different valving..
