Any advice?

I would check the rear bowl float levels (not sure if you have a single 4bbl or dual 4bbl) and depending on what you find, lower them a little.
Especially if you have reverse mounted dual quads the primary bowls are on the rear and typically have a higher float setting (fuel port on bowl will be set higher on the side) and when you hit the brakes hard it tends to flood the engine through the fuel bowl vent in top of the metering plate. Just the opposite of what Holley originally designed for. So you may need to lower the rear bowl fuel level to well below the viewing port.
