Is your coolant mix half anti freeze half distilled water do you have a over flow and have you tried something like water wetter to it.

Thank all of you for the great ideas.

I will take this list and start checking them one by one. I'll let you know what I find.

I'm sure at least one of these is part of the problem if not all of it.

More later and thanks once again.

I am not trying to call anyone out here, but the temperature of the thermostat will have little effect on whether or not the car overheats. The thermostat is simply a regulator and if all is working well in the cooling system, it will determine the temperature at which the engine runs.

Right. Once the temp goes past the thermostat setting, it doesn't matter if it's a 160 or a 220.

My quick thought. If it runs hot at idle but not on the highway, not enough airflow. If it runs hot on the highway, but not at slow speeds; not enough radiator.

One more. I see you have a 400 block. When these engines are rebuilt, many people fail to add holes to the head gaskets to allow for flow through the steam holes that the 400 block has due to siamesed cylinders. This causes these engines to run hot. Just a thought.

A very good point, and one that I missed... Good catch!

Would the fact that it is a Bowtie Block instead of a regular factory block make any difference?

Thanks,
