Re: ???Coolant Temperature Sending Unit???

The more accurate reading would be where you have the mechanical sender bulb in the head, the intake port where you have the electric will read cooler....

210º is not out of line for a big block. There should be another one of the head ports on the passengers side at the back of the head by #8. The temp there usually reads a little higher than the one on the drivers side by #1.
