By whatever means necessary …
Do you know what is out there for me to make it look old and clean? I know I can route wires in hidden locattions but what about the other details to give it an old look?

I'm sticking with the 350 because 1)I have a Whipple for it, 2)I have a marine intake for it, 3)my exhaust is already done (including headers), and 4)it came stock in the truck. Basically, I'm too far into it to even think about swapping to an LS. (some of you guys may see it otherwise, but that's my view)
I do see where you getting at with the "clean/old" look of the engine bay. Now I know why they put those plastic covers on all the new engines! (again, my opinion)
If I were to start fresh (no matter the truck) with it completely stock and in need of an engine, I'd probably seriously consider the LS.
). The HP I would gain from doing a cam, intake and such on the 350 is already there in the LS....why pay for HP that you can get for free( idealistically).
