This is a very common problem with certain carburetor designs that have
the fuel pickup from one side or the other of the float bowl. Raising
the float level or increasing the float needle size (where feasible)
sometimes helps a little, but the only cure is multiple fuel pickups or
a concentric arrangement of fuel reservoir and emulsion tube. One would
think that the fuel would not be affected that much, but a cross section
of the fuel in the float bowl of a car turning at .5 G would show the
fuel surface at a 45 degree angle--the float needle is held shut while
one side of the bowl is dry.

I'm glad to hear I'm not the only one. I'm also sorry to hear Chris K.
already tried the high-volume route. I'd considered that as the next
experiment. I'm hoping the same problem won't surface with the SUs.
The only other thing I could think of was perhaps something in the
engine bay to the left of the engine (hood stick?) was fouling the coil
or distributor, somehow causing a short which is not present when the
car's stationary or at least not in a hard left turn. Certainly has me
stumped!
