Robershaw Thermostats

I had one in my 454SS truck. It could be over 100 in the shade and that thing ran cool as a cumber even when beating the snot out of it. I have not looked into one for the Dodge yet, but I got my last one from Summit.

if your talking about the hi flow Mr Gasket they have a hi fail rate, never seen a Robert shaw unit where do you find them?
