First Drive after building, Major shake

The fact it's got + Camber, while most modern radial equiped cars run neg, leads me to believe that the alignment was set to original bias ply spec.
Take it back and ask nicely if they could possibly try to get it closer to the chart posted.
Achieving neg camber will help in the adjustment toward +. Caster.
The more + Caster will give you greater directional stability.
It may be nec to install Moog K 7103 offset bushings to achieve 2 1/2* or more caster, if you're a spirited,competitive driver.

Good luck.
