Installing Tempature Guage
I am installing a aftermarket mechanical guage kit that has an RTD lead to go in the place of the temp sending unit, but I would like to keep the factory guages working too. Any tips on how to install both??

It will work in a Tee, I've done it. So long as the coolant can get to it.
Also, on my 390 there was a spot on the neck that bolts to the manifold and I put my other sending unit there and left the stock one alone. Looks cleaner this way.

You do not get as accurate of a reading using a Tee because the coolant is deadheaded in the Tee and not constantly moving across the bulb of the sending unit.
What engine do you have? Some have more than one place to put a gauge.

Check your thermostat housing for an extra plug that isn't being used. It works fine there but doesn't show much untill the thermo opens. I like that because you can compare the two gauges if you have a bad thermo.

If you feel up to the task of pulling the intake you can drill and tap a second hole for an additional sensor. If you do this make sure you clean ALL of the shavings out of the intake before reinstalling it. I have an aftermarket aluminum intake on my 460 that already has 2 or 3 threaded holes and I have my mechanical sender in one and the electric in the other.

The 400 doesn't have water passages in the intake. You could make up a fitting to put into the heater core supply hose. This would give you an accurate reading since the 400 only has 1 temp gauge fitting in the front of the engine.
