couldn't you T into one of the oil cooler lines or the oil pressure sender? I also know on some small blocks there were oil senders in the block just above the oil filter along with the one behind the intake.

You could in theory "T" in an oil cooler line if so equipped .
The port on a SBC above the filter is tapped 1/4" NPT , the one behind the distributor is 1/8" NPT . BBC uses a 3/8" NPT above the filter and 1/4" NPT along the pan rails .
IMHO , all fluid temps (Oil , Trans, etc) should be measured in the sump , as that is the fluid that the engine (or trans , etc) will be using.

I'm running the '165 with 6E, but eventually will go with the '727.
Three wire GM I think would be the easiest since the resistance is known, but do other manufacturers use different resistance, etc.? I'm not opposed to another manufacturers product if it can do what we want.
This brings me back to the Napa Echlin catalog, which I recall listed everything about the sender/switch...number of wires, "high/low" resistance numbers, thread/pitch, etc. I wouldn't mind getting my hands on one of those, never could find it online.

Let me know which part #'s you need info on , I worked at NAPA and still have most all of the catalogs as well as Pro-Link on line

The oil pan/sump would be best but if you can't use the oil drain plug it invloves removing the pan.
T-ing into feed line to cooler sounds like a good idea! If you have a cooler. Although I don't know if I would want to mess with those lines? T would also have to allow tip of sender to be in flow.
The other plugged openings don't sound like a good flow and to small for any sender we know of yet? Nasty Z seems to know quite a bit about the chevy engines and maybe he knows if one of those plugged holes has good flow if we found a suitable sender.
For me if I can't get data into log and only a gauge I'd be loosing intrest is why I like the 3 wire GM CTS sender.

Yes, I think we are going to need to come up with something substantially smaller if this is going to work. I agree the pan is the better location, it's just a matter of finding something to fit.
I had hoped the oil pan threads would have matched the sender body.
I have a couple of ideas , let me ponder it tomorrow .
I need to take the sensor and see if it can be "massaged" into fitting into a 1/2-20 hole

I know what your tinking but don't have a 1/2 20 die...

Tom, you don't happen to know where, if anywhere, the echlin catalog is available online do you? What I liked about it was you could simply look at all the different sensors, and just pick one that had the right features for whatever you wanted to do. I remember looking for coolant fan switches. The catalog specified the on/off temps, so I could pick one that worked when I wanted it to, without having to wade through the painful process of picking a vehicle and drilling down. Kind of like the Dorman catalog section on wheel studs. No application listed, just the pertinent specs for you to make a decision.
They may not even print something like that anymore.
I like this. I come up with crazy idea, you execute it! :)
Just team work!

It was Nasty Z that made me do it!
Since the three wire CTS was about 5/8 I took most of it off with the grinder, then thought it has to seal with a plastic washer like a drain plug... so I put my drill in the vise and chucked up the sensing end and spun it on high while using a file to get the bottom of sensor bolt/nut flat and diameter down to a size that would fit in die and let it get started. Little oil and poof!

That was quick!!!. Looks good. Is that connector a "1 on top of 2" like a triangle?

Yup, same as part number Robert listed earlier.
The thread took all day, but the work on sensor was only 30 minutes. Now if the kids IH has the same oil drain plug as a chevy I'll wire it into the trans temp pin on 16197427 PCM right? Cause I think it was mentioned earlier that my 1990 Suburban oil pan would be metric... and I doubt I have an extra pin on 1227747. Suburban is bone stock other than chip...
