No, they are not the same size. I can get the diameters soon.

Thanks Kevin , it is maybe a radiator from a 67 or 68 , it fit the radiator support and have the original brace on the tank

That is the correct lower hose.  The lower hose is larger than the upper.  The upper hose is 3956662.  The upper outlet is hard to measure on my 69 350 SS 4Sp but it is about 1 1/2 inches.

It meens the radiator is the problem , the radiator fit the support correctlly and i don't have the tag that identify it , can it came from a firebird?
