Over heating but not...
Heyas all..
I have an old '79 F250 (2wd/460) that I'm slowly resurrecting from a beat up old farm truck..
I have her running really well again, although something is happening I haven't seen with other cars/trucks..
The water temp gauge doesn't go above 210F, oil pressure is fine, etc...
Although when she gets hot, as in driving 30+ miles @70, she doesn't want to start again until cooling down - it may only take 15 mins for her to cool down enough, but its annoying, heh
Starter turns over fine, new carb/electrical, etc.. Thermostat is 180 (iirc) is there anything I'm missing or over looking? When she does cool down, she starts right up.

Heyas,
I do have a mechanical water temp gauge on it already, no AF or water is puking anywhere, nothing - she just doesnt want to start up after ran for a while :-/
I haven't checked the timing with everything else I've done to her - that will be first on my list now

'could be a heat soak issue (vapor lock) or the carb has an internal leak letting the fuel drain out of the bowls and causing a flooded condition. When the latter happens, the leaked fuel inside the manifold needs enough time to evaporate before restarting.
With the potential vapor lock issue, try to shield the fuel line to see how it behaves... drive a test loop back to your home to avoid getting stranded.

DuraSpark electronic ignition introduced in 1974, but not all vehicles came with it until 1976. Ignition module located on left fender inner apron, just in front of firewall.
Engine heat, especially radiating from a V8's red hot left exhaust manifold, is the mortal enemy of these modules.
When the module overheats, the engine dies, when the module cools down, the engine restarts.
But...sooner or later...usually sooner, the module overheats, BURNS OUT, now the engine will not restart.

I have the same issue with my bump. I'm running an eddy 4 barrel toilet bowl that likes to leak. After running for awhile you have to give some major air (like wide open) to get her to fire. She fires fine cold. I'd start with carb.
