Some random thoughts :
Have you verified that the fan starts running and stays running as the temp
gauge moves above center ?
How much above does it move ? A needle width or so is probably nothing to worry
about, it's just the thermostat opening farther.
Has the radiator been recently rodded out ? Tested for efficiency ?
Is there a shroud around the fan ? And is it reasonably well sealed to the
radiator core ?
What are you using for coolant ?
How much voltage is getting to the fan when the temp gauge is climbing ?
Are you sure your timing marks are accurate ? If the rubber in the damper
shifts, the marks will be wrong.
Don't know that any of this is your problem, just some things to think about.
