Single or double?

I've been lucky enough to never have any such sores or lumps.... Got it. I will redo all that shortly. Just trying to get it so I can run it around the block a few times. I looked at the lower radiator hose, the routing seems ok to me but maybe I'm missing something.
lower rad looks okay from the pic.

just for future edification, on V8 69 on down and 70+ are their own systems with timing covers, water pumps, dampeners, pulleys, (some) brackets being specific to each set.

this doesn't necessarily affect you in that you've got a later 360, but it is something to consider when trying to upgrade things like the radiator, fan, power steering or AC
