Radiator core upgrade

Has anyone had there stock 2 core upgraded to a 3 or 4 core? If so was there any clearance issues with the fan assembly? 71 Duster 340, lunati voodoo cam, 7 blade mopar fan with clutch. Thanks
I don't know if this helps with your application, but I replaced the original radiator in my 64 Valiant with a three row aluminum radiator. Slant 6. It fit just fine.
