I have a 1981 C3 but with what seems to be a 1972 C20 350 block and i am looking to connect the oil temp gauge to the sender but there appears to be none in the block right now. After searching this site i think i have found the location but would like to get it confirmed before i buy a sender. They look to be expensive.
That is the sensor location and the RockAuto sensor is the one I got for my 81 as well. Works great.
My car has an aftermarket block and the previous owner never cared to hook up the sensor.

Thanks for confirming! Just do not understand why the water temp sensor is only $7 and the oil temp sensor $50?
Also, i am guessing oil will pour out once i remove that plug in order to replace it with the sender?
That is the location for the oil sensor from the 81/82 C3's. My 78 has had an oil temp sensor and gauge (in place of the dumb mechanical clock on my car) since 1985 when I installed it myself. I had to remove the oil pressure sending unit from the location above the oil filter (relocated to behind the distributor) to do the install.
The oil sensor is so expensive probably due to the fact that NO GM car back in 1981/82 had an oil temp gauge and that part is only for the C3 in those 2 years most likely.........

This is a sending unit, not a switch. Maybe the description in your link to Rock Auto is misleading. But here is one that is a temp sending sensor to gauge. They look the same but......
