I still have the date coded 1957 radiator in my LCF, I flushed it out and cleaned the air side of it when I had it out of the truck. It has the original 4 blade fan and shroud, 283 V8 and it does a great job. Of course it only has to cool the engine, no power steering, no a/c, no automatic trans. Now my 2500HD has a cooler for everything.
