I hate Portland too...I'd rather drive around anywhere but there. LA was easy in 1976. Lunch box/ice chest, bottle to pee in and a good book. D/FW, whole 'nother story....106 degrees, 100% humidity, a Ford 460, the mixmaster south of there can really eat a vehicle up fast. BUT, I had to wonder about the 1 inch, those are aluminum and don't have the cooling properties as brass and copper do. Hence the need for 1 inch cores=3" total thick. I had heard of adding depth to your radiator, as it could take it in the hole its going in. 383 is not the hottest running, or coolest running either, depends on build. But the radiator needs either the dual fan-1 is used to work with the thermostat, and the one that works with a heat sensor. It generally comes on after X # of minutes of the other one popping on steady, to keep the cool thing happening. I was told it's not rocket science. Bad news, I'm not a rocket scientist so....like to keep track of how it works out-I still feel uneasy about our Dart, put way to much into the rebuild to cook it somewhere when I don't have to-and for MoPar's it's always "For a few dollars more"...yeah.
