Ok, thanks for all the great advice, I went to midas, and for 20 bucks they made me an awsome upper and lower pipe. I have to bring the lower pipe to have it bent a little more. As far as proper coolant flow, my truck has a DT360, and the truck the radiator came from was a 5.9 Cummins. My upper engine outlet is only 2.25" OD, the radiator is 2" ID, so they are almost the same size. For what ever reason International made the lower engine inlet 3" OD. From what I understand it can not move anymore coolant than the upper outlet can move.
