Hot start

[vectorit]

I've been noticing a problem with my burb, and it is starting to bug me with what could be causing it...

Drive for an hour or so, park and turn off the engine.
Come back a few minutes later, go to try and start and it just turns like the coil wire has fallen off. Starter is turning the engine just as normally as if it was any other time to start.

Wait five or ten minutes, and she fires right up.

This doesn't happen all the time, but when it does it happens of course at the wrong time. (In a hurry).

The under hood inventory...
327
Quadrajet
Original rams
Original cast iron intake
strong battery
strong starter
Manual trans
Pertronix ignition, this problem was present when I had the points ignition.
Plugs are AC R45TS, gapped at 40.
Timing is spot on.

The only piece of hardware that is possibly a weak link in this, is the plug wires since they are old but not damaged. I've just put off on getting new ones, just wondering if they may be getting in the way of starting on hot days.

What I have noticed when she does eventually fire, is it seems like it is flooded. Since when she does fire up, I notice some black exhaust. Though I don't smell fuel. I typically don't even press the go pedal prior to starting when the engine is already warm, but when this happens I have to press the pedal down a little it seems.

EDIT: added the type of intake manifold

Any thoughts?
