[Spridgets] Water pump

Well Ron is more of a cooling expert than I am!
 
I agree with Ron that you appear to have a problem that's not going to be  
solved with any water pump unless what you have is broken or seized.
 
You don't say what kind of radiator you have - modern core design or  
copper/brass or whatever.  You don't say if it is vertical or cross  flow.
 
You don't say if you have a thermostat or not and if you don't have one and  
are using a blanking sleeve you don't say if you have blocked off the bypass 
or  not.
 
Have you checked the temperature reading with a different gauge?
 
You don't say what pump you have or what pulley it has on it - have you  
pulled the pump to see if the impellor is even still attached to it or is it  
jammed hard against block.
 
Given you have cooling problems at idle and race speeds the rad looks to be  
the culprit.
 
What is 240 in Centrigrade - about 110C.  I've run my engine up to 110  if 
not 115C momentarily when doing a cooling system test but generally like it  
below 105C if not 95C.  However, I don't think the oil temp has ever been  over a 
100C (even on a very long dyno pull) and certainly not at the those temps  
when doing a cooling system test (or on that long dyno pull).

You've probably already  damaged the head. Get the head and block flat and 
get a Ron Davis radiator. If  you're running 240 in both conditions, you're 
picking flyshit out of pepper  with an electric waterpump discussion.
