im running a 4th gen radiator/fans due to accessibility, ordered some hoses today and they fit on the 5.3, but are way too big for the 4th gen radiator. There’s no way I can use them. Any one else run into this problem and figure out a solution?
I ran into a similar problem when I put my 400 in my 91. I ended up using the original top hose on the radiator and spliced on a piece of straight hose to the engine. There have been a lot of LS swaps someone should chime in.
