Thank you. Is the water distribution tube a channel in the block? Or is it a replaceable tube?
I am asking to see if I need an extra part on hand or is this simply a matter of clearing out an existing channel in the block.
Now that you mention it, the rear of the motor was running about 10 degrees hotter than the front (measured with laser thermometer)

I have a 1949 Packard fastback 327 cu in straight 8.
In summer time, it is running about 215 degrees F when idling. I just had the radiator rebuilt (recored) and have some small improvement. So next on the list is the water pump.

I have removed the thermostat and also have some small improvement. (It was a 160 degree thermostat).

The local mechanic tells me not to worry about the engine temperature. (He is an antique car mechanic) But something tells me that 215 degrees or any amount over 200 is too hot.

These cars were parade cars. Are you telling me that on the 4th of July, you can't have the car idling in a parade on a 95 degree day and expect the temperature to stay below 200 degrees F?

So the question is, is it reasonable to assume that I can work towards getting the car to stay below 200 degrees F on a hot day? After replacing the water pump, what is next? If it still runs hot, could the cooling channels of the block be calcified and thus affect the cooling ability of the cooling system?

I would appreciate an experienced enthusiasts comments.
