I have a next to new (1500) miles radiator. My bronco overheated with that and finally the new engine blew up. I swapped it out for a four core and put a new bp408 stroker in it. I am coming to golden sunday if you want it $25.
PS: I have a 351w long block (the rebuilt one with 1500 miles) that died from overheating if you want it. After it blew up I paid $2,900 to put it right. It wasn't right, 10k gone, I gave up and went to BP and another shop. It was about 400HP, so it has a good cam, rebuilt heads, pan, and all of the internal parts are good, maybe. If your interested for $1k talk to me.
