The formula for converting °C to °F is [ 1.8 * C + 32 ]
which would put you around 230° F, if you believe your gauge.
A 40% anti freeze mix will probably put you up to 240-250 boiling point
with a 7-9 PSI relief valve pressure, so even if the temp is true, you
should
not be boiling yet.

The temperature at the top of the radiator, should be identical to the
temp
at the water outlet, where the transducer is, UNLESS the thermostat is
closed.
As a final test, I would recommend starting the car from a warm
condition,
with your meat thermo sitting in the open radiators coolant.
This will let you see if the coolant really boils, and will allow you to
correlate the temperature on your gauge to some other "more trustworthy"
device.
You should get several minutes to make your correlation.
Hey, did Lucas make those damn temperature sensors too?
