Oil temp is "ballpark" around 220-240 with dino, 210-230 with synth. This helps eliminate moister ect, and oil temp normally runs a few degrees above the engine coolant temp. For an LT1 with a 190 Thermostat will have an oil temp around 210-230. With a 165 Thermo = oil temp in the 190-200 range. This is during normal driving. Hard use higher RPMs will raise the temp, you don't want to go over 300 degrees or the oil thins out allot and you will loose pressure.

My 350 CI with stock pan and factory oil cooler ran about 210 Castro semi-syth 10-30. In my 385 with the lower temp thermo, canton pan and no oil cooler I run about 195. Castrol semi-syth 10-40.

Also, you want the sensor in the oil pan, not in the block so you don't get false readings.

Nice trick I've seen is to drill and tap the sensor right into the drain plug if the pan don't have a fitting.
