Neeek is rolling towards a roundabout at about 10km/h. He thinks he can make it before the car to his right hits said roundabout, but decides against, so hauls on the anchors and comes to an abrupt stop. And the mighty ZH stalls.
Of course there's more - Neeek has to try and crank her over again which involves a lot of starter motor noise but no actual V8 noise. And naturally, Neeek has flooded it. So he and he alone pushes nearly 2 tonnes of ZH across the roundabout (thanks to all who helped...) and to relative safety on the other side, making sure that no-one has a nasty "shit, there's a dirty great car with the bonnet up in my way and I have nowhere to go and no way of stopping in time" moment.
Wait for abour 5 or 10 minutes and try again - that familiar V8 burble erupts from the rear of my car, and we're off again. It behaves itself the remaining 2 kays home.
So my question is, why would a sudden stop cause my engine to stall? 302C running a 2-barrell 350 Holley.
Many Holley's flood under heavy braking, in fact, I can't remember a time when mine did not flood under braking. It's an auto reflex for me to keep my left foot on brake and right on throttle at the same time.

That would certainly explain it, but at the risk of offending Holley-lovers the world over, isn't that... well, a bit crap?
Check your float level. If it is low, when you hit the brakes the level, or what there is there, may surge forward and starve the ngine of fuel.

You could be onto something there... float level has recently been tinkered with and it's lower than it was before - was literally spewing petrol previously.
Methinks a little more tinkering may be required...

Just get a 4 barrel... that way only two barrels will flood...
Sudden braking might have caused fuel to splash out the top of the vent tube (especially if your float level is too high) which would have flooded the carb. On 4bbls racers normally run a piece of rubber pipe between the front and rear vent tubes to prevent this happening.
Does your idle drop at all when you apply the brakes as it might be a vacuum leak from a stuffed master cyl that caused it.
