Re: "It just quits"..........

Well, if I've learned anything from this whole exercise, it's that one problem leads to another, and EVERYTHING is linked to 'the next step in the process of restoration'. It now appears that the 'just quitting' issue is linked to overheating. Even with the electric fuel pump, the motor is still stalling and I think the gas/carb is just getting too hot and vapour locking. Which leads me to the next question: How to cool the engine down?? The grill louvres are opening fully, coolant level is fine, heat gauge is showing just over half, and I have removed the thermostat. I see the cooling issue in two parts: circulation, and cooling ability. Are the rads in these cars a chronic problem? I am thinking a re-core may be needed. A reverse flush of the block and maybe even a new water pump; do they lose circulating ability with age?? (it's not leaking). Has anyone experimented with additional heat-dispersing 6 volt fans?? I tried driving on a back road with the exhaust side of the hood up (not too fast, obviously) and the gauge stayed at half - a little better.
I believe if I could cool things down, the vapour lock issue may disappear; any thoughts???
