What would cause my engine to die when hard braking?

With that tidbit of info,I am confident fuel is sloshing into the throat flooding and causing the stall.I'm sure when it restarts that there is at least a puff of black smoke out the exhaust.All that is needed is some rubber hose,can even be clear that you put from vent to vent with a hole or "V" cut in the top middle.Problem solved

My life is never that easy when dealing with these old cars.

So, spent some time playing with the car today and learned a couple of things. First I took off the air cleaner and put a couple of 3" pieces of hose on the vents and left them sticking straight up. Got going down the driveway and hit the brakes and it died just as before. Looked at the tubes and they were dry. I then pulled off the back fuel bowl and believe it already has the whistler installed as well as long jets. Any other ideas out there???

does it sputter or just plain turn off? you might check for a wire grounding in the ignition circuit when you hit the brakes. just try wiggling everything while it is running.

Still say it is a forgotten characteristic. Like Bias tires and sealed beam headlights. We forget. Have not had to slam on the brakes for about 15 years.

When I lock up the brakes, it dies right away. Coming to a normal stop while downshifting like I always do, it is not an issue. If I put the car in neutral and use the brakes only to slow the car, the engine rpm goes way down and almost stalls. I will check the wiring, but it is all new.
