I searched and found several references to using an 82 Riviera w/5.7 upper radiator hose for this LS1 swap into a 69 chevelle. Does this fit the stock small block radiator or the big block? The big block one is about 33 inches wide I think. the small block one was only 25 or so and that puts the upper neck in a different spot.

it fit mine which was a "3 core" and I believe 33" wide

some chevelles I've seen have a "4 core" but I believe the width is the same

a note is that you want to make sure the Buick 5.7 is the diesel engine option

thanks. I have the 33 inch wide radiator too, so this should work fine. one more item checked off the list.
