Where to put water temp sensor?

I need to mount my water temp sending unit (no locations in heads). Currently the fitting on the right side of the intake was going to be for the electric fan sensor. The other is for the heater core. I have a couple of thoughts and was wondering what would be better. I don't want to have to remove the intake to do this. I can either drill and tap where the arrow shows, d&t the thermostat water neck, or maybe get this. I was leaning towards doing it on the intake where the arrow points. I would think that it's dimpled there to allow it to be drilled. So there should be enough material there to do so. Any input? Thanks

The tapped spacer is ideal, by 'heater core' you mean radiator, right?

That spacer looks like a good clean solution. No drilling and taping, clean and easy.

Nope the heater core in the firewall. The spacer would be the simplest solution. I'm not looking for the easiest way, but want it to hold up.

Temp Readings

I have a head mount and was concerned with Temp readings when I bought my car. I finally bought a laser temp gun and found the head location increased the readout on the gague by about 10 degrees. I also have after-market headers that probably increases the higher sensor reading. The sensor is about 1 inch from the pipe. Probably the stock cast iron headers would absorbe more heat.

I'm more confortable reading 200 now that I know its really 190.

I have one mounted in the heater hose GOING TO the heater. (Can't put it in the return hose, the temp is affected by the heater cooling). That's an easy mount and works well.

I've searched on the net, and looked through edelbrocks instructions to see if it's alright to do so. Didn't come up with anything. Might contact edelbrock and see what they say.

The reading at the cylinder head is actually higher than the intake regardless whether you have stock manifolds or headers. It is closer to the combustion chamber than the intake.

The temp gage sensor in my T-Bird is in a heater hose.

Another bit of info on this-----if your heater controls shut off or restrict the water flow, this will NOT work

For instance---the heater controls in my 79 C-10 only operate doors in the heater box
The heater control in my 59 Elky (Vintage AC) shuts off the water flow to the heater.
