When I do some hard braking on the 68 1/2, the car seems to shut off and come right back on. Just started experiencing this a couple of days ago while doing some exhilarating driving. It now happens frequently when I hit the brakes hard.

Check the wires at the brake pedal switch... these get burnt from 6 tail lights. may be shorting out?

It could be your float level. What kind of carb do you have?
Running holley 735. Floats have stuck before, but it did not shut off.

Morning, are you up early or out late? I'll check the switch in just a few minutes. BTW, talked with Greg last night, great looking cat. Thanks

Thanks for the help, looked at switch all good there. Tapped the carb, drove it around, all seems good.

Wouldn't a bad brake pedal switch cause it to die every time the brake pedal is depressed and not just under heavy braking?

The rear float level may be set too high. Under very hard braking,
fuel can slosh out through the slot at the top of the metering
block, up and out the vent tube dumping into the secondaries.
This excess fuel will cause the engine to momentarily die.
The factory carbs have a brass baffle to help reduce this problem.
On road race cars, we install a Holley vent whistle to eliminate
this problem.
