Loadmaster,
I hear you and I HATE this problem. Particullarly, surging in high g-force turns.
With the Carter-type carb (read Edlebrock) the only thing that will help is more fuel pressure. If you kick it up to about 10 psi with a high performance fuel pump it will really help the problem, but your fuel mileage will be worse. With my Quadrajet (same thing), I run two electric pumps, one stock and one 7 psi Carter. Switch on BOTH for autocross.
I'll let you in on the real racing solution for this problem. It can be completely solved on a Holley with the use of jet extensions. They are little tubes that you solder onto your jets to reach the far side of the float bowl. They act like minature reservoirs that keep the fuel where you need it. There are also screw-on jet extensions that move the jet outwards. These require notched floats for clearance. For autocross, I ran a Holley 650 DP with soldered-on jet extensions on all four jets and it never stalled in any rapid speed changes or high g-force turns. Try it, you'll LIKE it!
