1957 283/270hp dual quads drag testing on a 350

Update as of Sunday PM; 20 Sep 09.
Installed wedges under the carbs made of wood I milled (Moroso wedges were back ordered). Was rained out last weekend.
Today the motor ran quite poorly very much worse than before the wedges. The car launches okay then really starts running bad. This time observers told me it was puffing black smoke during the early part of the accelleration. To me, at the wheel, it almost started to miss but simply stumbled. After the acceleration slows it starts running okay at the top end about the time it is shifted into high gear.
I'm thinking the carb wedges screwed up the float/fuel level geomtery in both carbs such that something is flooding under the acceleration phase of the run. I may need to reset the floats for the wedges. Any ideas?
Oh yes I blew the rear end gears today. At least 2 weeks maybe 3 to get back testing again.
