Engine dress and hose clamps?

Over the weekend I came across a local car show. From rat rods to dusters (well, one), several Chevys, and an R8 and Mclaren. Lots of those Chevys appeared to use those types of kits. Looked good in some, others reminded me of a honda.

I guess I don't see how they would be considered junk. I mean inside it's still a rubber hose being clamped so wouldn't it be just as secure against leaking?

If I could, I'd like prefer to have some kind of AN fitting on the end of each hose.
