If you go with and upgraded core like a four make sure you have the clearance between it and the fan. There was a thread on here a few months back where the thicker cores caused clearance problems. I purchased mine from ClassicParts (Standard Capacity) they mention in their catalog the issue with clearance for the Desert Cooler style they sell as well. Utah summers see 90-100+ deg days and my truck (rebuilt 54' 235) would vent a little pool of coolant after a long drive but I added a reproduction condensor tank which eliminated that. There are lots of choices out there, good luck.
