360 running hot

I run a 360 block 408 stroker. I ran 215 - 220 degrees in the summer. The same fan and radiator were in the car with a 318 last summer and it never got over 180 degrees. I opted for a Champion aluminum radiator with dual electric fans and shroud. I occasionally hit almost 200 on a very hot day, but it runs cooler in stop and go traffic. In traffic it sits around 180 and once in a while as high as 190. I am running a 180 degree t-stat as well. Go aluminum. You will not regret it.
