The car stalls from too much air too soon, not too much fuel. Under the conditions you describe, the motor is in a huge load / no manifold vacuum condition. The primaries and the secondaries are wide open to the atmosphere. The rpms are too low to generate enough air velocity in the intake manifold to provide the carburetor enough vacuum signal to pull fuel and the accellerator pump has already reached the end of it's stroke so the motor runs out of gas and either bogs or stalls.
Mike didn't say what carburetor he has. I'll take a guess that it's a vacuum secondary Holley. If it is, the condition can be adjusted by changing the springs (stiffer means slower) that allow the secondaries to open. They need to open slower so the carb can keep up with the fuel demand. Holley sells a kit with several springs at different spring rates so you can tune the opening of your secondaries.
