Normal Coolant Temp
I am thinking of changing t-stat and fan setting. Before I do can anyone tell me the "NORMAL", not what you think it should be but what GM intended the normal coolant temp to be on these cars when new from the factory. This will let me knw if mine is running the temp as designed. 96 vert LT1.

I spent about 45 minutes observing the coolant temperature operation range on my stock (never modified) 95 LT1 with 50,000 miles. I started the engine and let the temp rise. All of the info is while at idle and the outside temp 80*. Idle temp reached 228* before both fans came on and never saw the temp past 230* via digital guage. Analog guage was in the hash marks and showed approx. 250* from guessing, 260* being the highest number which is miss leading(digital and analog come from different sensors/senders). The temp dropped to 217* and both fans cut off. With the A/C on the temps sat around 201-205* and never got lower or higher. This I consider normal at idle and when driving at about 55 mph the digital temp guage stays around 185-190* range. 
My temps are the same. I also have a 95. I don't pay any attention to the analog gauge as it is way off.
