I posted this in my extremely sporadic build blog.

Thought if I put it over here it might generate a response..

I like instrumentation. Lots of gauges, especially on kind of expensive motors.
I told the guys at the motor shop I wanted to weld a bung in the oil pan for an oil temp sender and they suggested I put it in the oil filter adaptor.

Anybody out there that has done this? It seems like a good spot, but I don't know what the inside of the casting looks like to know where or even if it is possible without wrecking the adaptor or impeding the oil flow.

Thanks!

What kind of sensor are you using?

Was planning on using the typical electronic sender that works with Stewart Warner gauges.
I don't have one right here to give the dimensions....

So, this bad boy right here.

I'm thinking you need to make sure that you're taking the temp of just the oil, and not that of the surrounding steel. Getting the temp of the oil as it's flowing and getting it when it's static in the pan are also considerations. Adding it at the filter you can get it in the flow ...but it might also be blocking the flow. If it isn't blocking part of the flow .. it's also not getting an accurate measurement. Putting it in the pan leaves no question, you're measuring oil.

Agreed. I have usually just put the sender in the pan and not given too much thought to the possible differential in temperature between the temp of the oil in the pan vs that oil that is leaving the pump and heading off to the mains and top end. There may not be enough of a difference on a warmed-up motor to care about.
As I mentioned in the OP I am wondering if anybody out there in the big Olds world has tread upon this turf ahead of me, which is one of the great things about this forum!

Like I said, I like instruments.

I think there is a 12 step program for that addiction.

There should be for sure.
This setup is a result of roasting a Borg-Warner Velvet drive last year, so I'm adding trans temp and pressure to each engine.
Its pretty hard to hear what is happening from the 2nd floor (flybridge) when the motors are in the basement (bilge) so I call it cheap insurance...

I put a temp sender in my oil pan plug hole (bung) '68 442...screws right in, but it cuts down on road clearance a little, bent the wire plug. However, in your case you should not have any problems with waves lapping at your pan.
