well with the drilling for a new port, I can get rid of the stand pipe.

I guess the location of that sensor changes year to year.
In a different post, someone posted a pic of it to the right of the thermostat housing.
Mine is to the left of the stand pipe where the heater hose comes in to the manifold.
on the right of the thermostat housing is a raised flat place I plan on putting the new sensor.
So it shouldn't look as cobbled together as it did originally.

I think I can even do it without popping the intake off.
There doesn't seem to be anything on the otherside of it, so I am stuffing a rag behind it to catch the chips and shavings so I can drill and tap it on the block.
It is fairly easy with the thermostat out and the front of the motor off the engine.
