I had similar issues when I first put a good engine in our H/SA Camaro. It had been fine with our home-built 11.80 engine, but would practically shut off when the front wheels got airborne with the new power. We tried two professionally prepared carbs, borrowed a known working carb, three fuel pumps, two regulators, pressure up, pressure down, float level up and down, and on and on. We could make it consistent with extreme jetting, but it wasn't nearly as fast as it should have been.

One day I unbolted the fuel pump while the fuel lines were still on. As it dropped downward, I heard fluid moving when gravity took over. It was like in the cartoons, when a lightbulb appears over the character's head.

I re-mounted the pump a lot lower. The pump inlet is now three inches below the the fuel cell outlet, and the pump body is visible under the rear valance. The inlet had previously been about an inch below the cell. Picked up 3+ tenths the next weekend.
Don't know if the same thing will work for Bill or Chad, but it costs nothing to try.
