So I recently did the short water pump conversion on my 1957 Chevy 235 engine. So now the engine has 1.5 inlet and 1.5 outlet. I bought a no name aluminum radiator with 1.5" inlet and a 1.75 outlet. Several months ago I ordered replacement hoses from Rock Auto that were sized 1.25 inlet and 1.5 outlet. So in short I have a lot of parts that do not fit. How does everyone usually make all this work?

I did find a no name radiator on Ebay that has both 1.5 inlet and outlets. That would solve most of my problems. I think the 1.25 hose I got from Rock Auto is probably incorrect, but the 1.5 lower hose looks good and would make some sense. Why are 1.5 inlet/1.5 outlet radiators not more common or standard? I find it hard to believe when this truck was new it used a hose that went from 1.5 to 1.75. And I honestly don't see a point in a 1.75 hose because your 1.5 hose will be a bottle neck and slow your volume down.

Thanks for any suggestions
