That is a rather common problem with any carb.
You could have fuel slosh in either float bowl that is actually flooding the carb for a second or two. I'd try lowering the float level in the rear bowl, and see if that helps. It may take a bit of trial and error before finding the best setting.
Another old holley trick, is using a short length of fuel line attached to both bowl vents, and a cutout in the middle, pointed upwards. When fuel sloshes in the float bowls, it tends to splash out of the vent, and into the throat of the carb. This helps prevent fuel from getting into the throat of the carb. There's only one way to stop the slosh, slow down before turning...... Not fun.

Fixed that for you.

When I had my Holley (and my Edelbrock was the same way), I'd experience a stumble on left-hand turns, suggesting that the fuel was sloshing away from the primary jets. It would also stall if I stopped too hard, especially when going downhill. My eventual fix was to swap my Weber 45 DCOE back on. No regrets there.

This is a great trick. We used to do this all the time for 4-wheeling because we'd have the same problem when at steep angles.

This does happen to all carbs but some easier than others.
