Waiting for parts in South Carolina

TODAY IS THE TOMORROW I WORRIED ABOUT YESTERDAY
Good News and bad news:
The good news:
Both the clutch and brake master cylinders have been replaced, Clutch and brakes work well.

The bad news:
Record high temperatures here in Hilton Head South Carolina. You can fry bacon and eggs on the hood of the car. On the way back from the shop the car overheated...the temp gauge showed 235 F. I checked the engine block, cylinder head, radiator, water pump area and various points on the engine with a portable lase thermometer. The coolant and head was at 202F..it was not boiling..BUT there was so much heat in the engine compartment that the fuel in the carburetors was turning into a massive vapor lock. After letting the car sit for an hour I was able to start the car and after about one mile the fuel system was cleared of bubbles and started to run normally. If this heat wave continues we will change our route plans and stick to the northern states. Even though the thermostat, water pump, and the retro-fit electric radiator cooling fan are all working properly these temperatures are too much for this car to handle.

And yet another inconvenience:
wires at headlight dimmer switch keep falling off ( been bent too many times by left foot hitting it). Also, the main light switch fails intermttantly. Got both coming in overnight but won't be installed till Monday. Looks like we won't get underway till the early hours Tuesday morning.
