===================
Sure does NOT sound like a starter problem...(heat soaked starters
normally will not even make a noise much less turn the car over..)
sounds to me like a fuel problem..or even vapor lock ... Toss an
ice bag on the side of the carb for a few minutes if it happens
again...

Check the choke pulloff first, (when engine is warm
is the choke blade completely open)
then when it's hot and bucking, turn off the engine
and look down into the carb and look if you can see fuel
trickling onto the butterflies (stuck float).

How hot is hot? These old cars ran about 180-195 normally, but commonly
climbed to 200-220 due to lots of reasons. If hot, you need to check
radiator, fan, water pump, block rust, coolant ratio and condition, spoiler
intact, radiator seals, and so on.

If it is really hot, then you could have fuel percolating problems. Common
spots are fuel pump, fuel line, and carbs. Check that the fuel line is not
against the intake, block, or water pump. A heater hose could lay on the
line and overheat it.

People frequently cut the metal lines and insert aftermarket fuel filters
with rubber hose. These can be trouble spots as they can restrict the flow
and lay on the engine.

You could also have a bad or low capacity pump. I've run into many rebuilt
pumps which do not have the capacity for a big block. The rebuilder just
stuffs the generic parts into a housing, and then the parts store sells them
as whatever application the number on the side is. However, the stuff
making volume and pressure are not. The best case is to use a real genuine
new AC pump, or one from a respected restoration rebuilder. It costs a lot
more, (and I mean a LOT), but then the car runs like new.

Check the other stuff first.

You can buy new hi-volume fuel pumps almost anywhere now. No need to look
for an OEM pump.

Check for stuck choke or stuck exhaust header heat riser.

Another possibility may be rust particles from the gas tank clogging the
fuel filter
and maybe entering the carburetor, or even clogging the filter bag over
the fuel outlet in the gas tank,
restricting flow volume.

You could disconnect the fuel line and then turn the engine over with
the line end in a glass jar
so you can collect some gas and inspect for any sediment in the jar; or,
put a clear glass filter
in your fuel line so you can see any sediment there.

435's have three two barrels. Just replace the fuel filter and cut the old
one open and see what's inside. I've used about three feet of rubber gas
line and a small funnel to see what's inside a filter. Put the hose on the
funnel and the outlet of the filter. Hold it up by the funnel over a pan and
pour gas in the funnel. If the filter is full of crap it will come out the
inlet and be in the pan.
