So if I take the thermostat out of my car it will run too hot because the thermostat isn't there to slow it down through the rad?

We`re just talking here Joe, I`m pretty sure Tom got his answer so why not discuss something that came up during this thread. You refer what works for you but because it works for you doesn`t mean it works for everyone or every combo.
I have a milkshake that forms at the top of my heads where the cold water exits the block. It got way better at LOTO where the water was warmer. Wonder if that would still be the case if the block had some heat in it.
If cold block is so great why doesn`t everyone run without a stat on the street/endurance/strip?
I wouldn`t mind at least figuring out a way to run the water thru the headers first then to the motor.

On the outlet, or outlets, depending on how you're rigged. make sure your psi bypass valve is plumbed before your engine, and then restrict the outlets until you can maintain consistent temp.

As for ring gaps and thermal expansion, what do the oems figure in for thermal expansion? For example, in the northern states, starting a cold engine when it's -20* F, and then it warms up to 210*. Then you have some that have aluminum blocks as well as iron blocks. What are they running for ring gaps?
Also, has anyone ever compared the temp on the rear cylinders vs the front cykinders on a GM big block in a automotive application?
On the engine that is starting cold at -20º F, and rising to say 180º,, the components will all rise uniformly relative to each other. The key is uniformly.Their initial and running tolerances are designed based upon the various material and their relative rate of expansion.
In the marine application, where you may experience, a 100º difference in running temp from front to rear cylinders, it's obvious you may want to rethink your initial clearances (ring end gap and piston to wall).
There is no editorializing on anyone's part on the way Tom, or anyone else for that matter chooses to configure the cooling system. Just data.
