It’s possible. My 6.5 Litre air cleaner does not have the vent tube. I’m not up on all of the California emission stuff so maybe it’s possible that’s correct for an emissions state Cougar.

Here is good information from the Cougar Club of America about the 6.5 Litre option and what was chrome from the factory in 1967 & 1968.

Steven/Group,
So if I am reading this right you could get the chrome dress up kit, and the low restriction air filter with a car that carried the “6.5” fender emblems, not just on a GT?
My car has the “6.5” emblems
BTW if anyone ever has a standard base with intact snorkel and no emmissions tube they want to get rid of cheap please let me know. Wish I would have valued mine more all those years ago and not cut the snorkel off 
Non GT Cougar got the painted lid unless it was a Dan Gurney special option that received the chrome dress up kit. Only GT had the dual screen set up. Only the CA emissions got the vent breather tube.
The exception to that rule is Cougar one and the first production show units got the chrome kit.
Cougar 1 engine bay.
Great pictures and information. I was always under the impression and I could be wrong that all 1967 6.5 Litre S Code engines got the chrome dress up kit regardless of GT equipment group (GT model had the non snorkel open element base air cleaner). The only 6.5 Litre engine that got the blue painted treatment from the air cleaner to the valve covers was the 1968 6.5 Litre X code 2V engine. Am I off base on this?

Steven,
According to that CCOA article your not. At least from what I read. My 6.5 badged car has a chrome lid. Though I got the original engine block with my car it was minus the heads intake and valve covers so I can’t say on those. The air cleaner was in the trunk though. Is it possible that it was like one of those many Ford “quirks” that it depended on the plant or what box assembly line folks were grabbing parts out of? Or would the air cleaner have been on already from the engine plant?
On the example of the concourse engine above with AC, is it right that the compressor clutch pulley is black? Thought they were machined.
No engines were shipped from the engine plants without air cleaners. They were shipped separately from another plant or supplier to the car assembly plant
You may be thinking or have seen a service replacement or one from another application that was used. There is a version where the clutch is flush to the front face surface and service replacements were often plated all one finish.
Straight machine surface would likely rust quickly which would have been a problem for the dealer when it came sale time for for service departments since the parts would sit on the shelved for months of years.
Here is a picture of the same version as shown on that particular application all painted as a unit - it to is a service replacement (NORS 
And a couple of unrestored examples to go along with the other
My A/C clutch assembly looks like the bottom picture and is painted black as well.

Is the shell the coil is in and the 4 attaching bolts for it plated? I assume the bolt holding it on is black phosphate?
Thank’s to BosseElim69 for the priceless picture of the 67 GT engine compartment. I immediately noted the rubber molding near the windshield washer spray arm was detached just like mine. Also noted there were some very similar rust spots on the upper fenders. Sad to find out my air cleaner is not original equipment, but I think the bug screen covering my AC is!!
