HA!
That's the tube to the brake booster BUT you can see how close it is to the carb. I think you need to put it in a tube bender and get some more room out of it?
The pcv picture is funny! That picture is how you want to plumb it IF you actually want it to work BUT that's not how it was done at the factory.
The factory connection goes from the pcv to the nipple on the bottom of the air cleaner.
Why? Beats me. The system is almost completely inoperable hooked up like that?
PCV's hooked directly to the intake manifolds tend to suck some oil out of the valve covers and into the intake. It may be that there were early problems with that and essentially Ford/Shelby said screw it, run the hose to the air cleaner, that will stop dumping oil in the intake? Actually anyone's guess is as good as any on this one but the oil dumping makes the most sense to me?
