I saved up the money and got a new 033 from GlenRay. 68 3-core unit. I have no issues with cooling.
One day I will find a good rebuildable 065 that our cars originally came with, but could not wait to find one to drive again.
Having the inlets and outlets in the correct orientation is important. the BB 68 or 69 radiator has the outlet on the driver side and inlet is between center and the driver side. This will effect your small block you have now at (least on the inlet side). Glad I am not in your shoes. If what you have is functional, you may want to keep using it until you get ready to put a 383 back in.
