<VV> Running oil temp normalcy

[Stephen Upham]

	I have an after market temperature gauge that was manufactured to  
measure water but has been placed in service on my Monza to measure  
oil temperature.  The gauge has no outward indication that it is a  
water temp sensor.  The sender is located in the triangular crevice  
on the right half block above and to the right of the top of the oil  
pan near the skid plate.  I also have a dual CHT with the senders  
mounted under spark plugs #'s 3 and 4 and the connections to the lead  
to the cabin located in the engine compartment.    I'm experiencing  
higher than comfortable oil temperatures (265-270 as indicated by the  
gauge) when cruising at 65-70 mph.   It normally operates at about  
260-265 after having been driven for twenty to thirty minutes in the  
city.   The CHT never got above 250 which I understand could be  
90-100 degrees off although a handheld temperature sensor monitoring  
the head temp from the wheel well usually reads very close to what is  
on the CHT when measured while standing still (of course).
	I took the cover off and blew out the oil cooler (back flushed with  
pressurized air) and have just changed the oil (Brad Penn Racing Oil)  
and a Mobil 1 filter.  I am running the lower shrouds on because of  
the fuel economy issue, but it looks like they will be coming off for  
the summer.  The belt is practically new and adjusted so that the  
alternator fan can be moved with one finger under pressure.  The  
blower bearing is brand new.  The engine seal is in place and in good  
condition and I have Seth's plug wires and all fire wall grommets,  
plugs and boots are new and in place.  I'm not using synthetic oil  
yet as I am within that 5-10 thousand break-in period of allowing the  
engine gaskets to seal before attempting to use synthetic to avoid  
leaks.  I would like to have some opinions as to why it is running so  
hot and if and how that might be dangerous to the life of the engine.
