I had a 360 that was hard blocked you cant keep them cool in traffic or read lights Mine was 60 over andfilled to the top, going down the highway at 180 but in town it would shoot up to infinity.
My block is only half filled. I monitor my oil very closely and use an oil temperature gauge as well...Dead heat and traffic it sucks big time, but once the car gets moving and air gets to the oil pan temps drop a good bit...but once its hot, its hot, and it would be nice to have electric fans to help cool things down a little more efficiently, or even run them earlier than my current mechanical fan so that water and oil temps are more manageable.
