Where is a good location for my water temp sending unit to get the most accurate water temp reading.
Intake, water pump or thermostat housing ???

The head but you didn't list it,the water pump is the worst place.

go with the intake because it gives you a true temp of the motor as the water exits

put it on the manifold.by putting it in the head you will get a false reading,mostly because of exhaust heat,even if its routed away from that.

The front of the intake just past the thermostat. I like to put the temp guage there and the warning light in the head. Gives you a little heads up that way.

Newer GM small blocks ('80's) had them in the thermostat housing. Anyway, we've never seen GM engineers do anything bass ackwards, have we?

I've always heard that the manifold was the most accurate. From the factory, the sending unit is just to tell you to shut the motor off. On our cars, its to tell you what's happening under the hood. The idiot lights just yells "THERE'S A PROBLEM, SHUT HER DOWN!", but a guage tells what's going on. That's why I think the manifold is better because its an average of the entire motor.
