Nova swap radiator hoses
I've got a 5.3 in a '70 Nova with a stock size radiator with the outlet on the lower right side (1.75") and the inlet on the upper left side (1.5"). I also have an LS7 waterpump with the outlet on the driver's side and a straight water neck from Jegs. Not being a fan of spliced hoses, I did a ton of research and ended up successful. The upper hose is a Dayco 71871 (had to use a 1.5" to 1.25" reducer sleeve) and the lower is a Dayco 71904. A little trimming to both, but they both fit very well. Just thought I'd share.
Kind of hard to see the lower, but it's there!

I have a "front" steam tube on the back of the heads with a hose that runs up to a "tee" and ties into the actual front steam tube. A hose will then go to a 1/4npt bung and fitting in the radiator that I haven't welded in yet. It will go just below the filler neck.
