Leonard,
Have you checked:
- timing (retarded can cause overtemp)
- mixture (ditto too lean)
- radiator
- block internals (i.e. rust)
- thermostat
The pump would be the last thing I'd suspect; there's nothing to them and when
they
fail they leak or the bearing goes, but they still pump (unless they seize).
A balky thermostat can cause these symptoms. I've had trouble finding reliable
thermostats for both my Healey and my Ranger. After that, if you haven't had
your
radiator out and inspected and rodded in a while that could be the culprit.
Excessive
rust and/or "boiler scale" in the block can cause overheating too,
bs
