<VV> My Happy 4th of July (belated) plus heat issues

[Stephen Upham]

I took the Monza to our NTCA 34th Annual Picnic today.  I just have  
to say that I LOVE to drive my Monza.  Although the car is factory A/ 
C, I don't have it connected (no condensor or compressor installed,  
though I have the original equipment) so I drive with the windows  
down. It was 97 today, but on the highway to the picnic I was not  
bothered.  I had the wife to follow with the kids ( 4 and 1) in the  
Durango so they could have air. I have kept the lower shrouds on this  
season because I usually take short trips, and I wanted to make sure  
that the oil heated properly (220 degrees +) in order to avoid acid  
in the block.   Anyway, my Falcon dual CHT indicated that the temps  
were steady at 240-50.  Although this may not be "accurate" (due to  
the placement of the senders under spark plugs #'s 3 and 4) it is  
what has been the normal temperature since the rebuild two years  
ago.  What has given me pause is the oil temps.  They have been going  
to 275 which is just at the limit of my gauge (a converted water  
gauge which goes to 280).  The sensor is located just above the oil  
pan in the triangle on the right side of the block.  That is higher  
than normal as before this summer it was normally in the 240-265  
range.  I did have the shrouds off last summer, and that may be  
making the difference, but I don't quite understand why the CHT temps  
don't reflect that temp change.  I have used a hand held temp sensor  
(laser light  version that I bought at Harbor Freight) to measure the  
head, oil pan, and oil cooler when the oil gauge reached 275.  It was  
showing the oil pan at 240ish, the oil cooler at 205ish (measured at  
a small crack between the top plate and the side plate), and the  
heads at 240ish (of course after I had pulled over).  These are VERY  
deflashed heads and I am using Brad Penn Racing oil with a Mobil 1  
filter.  The belt is adjusted per the finger/alternator fan method.   
I feel that I need to install a second oil temp sensor in order to  
check the accuracy of the first.  Thermal breakdown is not an  
option.  I'm currently awaiting a shipment of new brake springs for  
the front and back in order eliminate that as a reason for the brakes  
not fully releasing.

P.S.  I plan to get out and drive on July the 7th in celebration of  
the 50th year since production began.
