My Cooling Improvement Project (hopefully)

I was using a high flow tstat and found that in cooler weather it was never really closed. Engine took too long to warm up. But any way Dart67 when trying to figure out cooling issues I like to see what the temp of the lower hose is like. This time of year around here the lower hose on my dart stays pretty cool as the radiator is able to get rid of mostly all of the heat. If your lower hose is as hot as the upper then you need more radiator or more air flow to get rid of the heat. Or tune till your putting out less heat if your running too lean or what not. Ive read throught this whole thread and it seems you've done everything right. Fans shroud ect. I've got a large 19" flex fan with 6 or 7 huge blades on it. Its off of some other old mopar. It moves a ton of air at idle with no shroud. It does a lot better than the smaller 18" clutch fan with shroud that was stock on my car.
