Top rad hose is flowing up and out of engine,through rad and down and out of rad into water pump. So what you would be getting is coolant as it leaves engine. A small amount flows as the bypass allows some around thermostat.
Seems to me that on the passenger side of the block are a couple block drains. They look like your sensor might screw right in there. I could be wrong, but when I got my ‘66 Dart I removed an aftermarket temp gauge setup and I took something out of the block drain. The ole memory ain’t what it use to be.Just by eyeballing it, doesn't look like i can replace the OEM temp sensor and this attachment while YES it comes with different size attachments they are all bigger than my OEM sensing unit. Is there a 1/2" NTP port somewhere on a slant 6 that Im not seeing?

Yes, I think there are two of them. They are in the block, not the head. Hopefully you aren’t working with an aluminum block. Don’t know those at all. Those block drain plugs are a bugger to remove—usually. Good luck with it. I hope the pipe thread is the right one for the sender bulb.The block drain would be a 1/2" NPT somewhere under the spark plugs?

When we couldn't get any of the plugs out of the 318 intake, we drilled and tapped this:
