It will, but will require new hose as the newer water pump uses smaller diameter hose. Just take the house to a partstore and have fun matching them, that is what I did with my 5.3L and stock copper radiator. And by the way, after 300 miles or so the stocker gave up and I ended with a LS-friendly griffin radiator.
