I remember the AFB which would be Carter or Edelbrock did real well cornering, acceleration and braking because of the dual float bowls. But it was prone to flood out or boil dry under hot soak conditions. That would be like full operating temp, shut engine off for 10-15 minutes, then try a re-start. The fuel in the float bowls would percolate out the main nozzles and flood the engine, or just boil dry, then it wouldbe a long crank to re-fill. Being all aluminum they would soak up too much heat. A class C application does not seem a good thing, but thick insulating spacer between carb and intake did help a lot with this issue.
Correct me if I’m wrong, but isn’t that why Carter came out with the ThermoQuad, to eliminate the boil over issue the AFB had?
One of the things my engine builder insisted on was a thick gasket. I went one step further and bought a NOS GM aluminum carb shield and modified it to fit the ThermoQuad. I should have zero heat issues, knock on wood.
