440 thermostat?

[Bird 426]

Yes, will be out in the garage in a bit. Will grab a picture of what you may want.

Copied and pasted this right from the Flowkooler webside. I believe you will want to search for a FlowKooler 370-180. They aren't cheap but well worth it.


The difference between the Robertshaw 370 Series and the 330 Series is the flange diameter.

Fits Mopar, Some Ford, Lincoln, Mercury, AMC L6 Buick Nailhead and Y blocks

I use a Robertshaw 160, when the car is at operating temp it runs 175-180 degrees…

I don't even run a thermostat and the car runs between 180-190 depending on outside temperature.

Hello - I followed your link to Rockauto for the Stant, it only shows Motorad. NO Stant products. Where did you find it?
This morning I called Advance Auto Parts, Autozone, O'Reilly, Napa, and Summit. NONE of them have the Stant Premium thermostats.
I need one (180 degrees) for my '70 Challenger RT.
Where can I get one?

Notice the date on my post...2021! Evidently Rockauto doesn't sell them for some reason. Try this if you're still looking: https://www.amazon.com/Stant-45358-...8&psc=1&mcid=1a5b6bd0fd043d8aa903e6ca77383ce8

I followed the link you posted here and was about to purchase it, but then it says it does NOT fit Dodge Challenger.
