Does anyone have a picture of an original 67 GT 390 PCV system?

What plant, time period - Thermactor/non Thermactor, AC/non AC ?????
Think that is it ;)

San Jose early car will get the build date off the door tag tomorrow I know the motor was assembled 9-14-66 and it originally had smog/thermactor. If you want any possible details from the car cause it seems so early let me know.
-
Still waiting on the build date from the customer, he took the door tag home. But the heater motor has an Aug 66 date stamped on it. So the motor was done quite a bit before the car.
-
Ok so the assembly date stamped into the tab on the block is 9-14-66 the tag on the engine is 6J as well, the build date for the car is 9-22-66. So if you have example of the pcv system i would be thankful for the help!
-
Ok = this is the most complete system all on one car - fairly early car - though the car as been played with. Note at least one hose has been replaced and allot of clamps are wrong or missing :( but it shows routing and much of the hardware. Hope this helps

So the valve covers that are on the car are different then in your pictures and I have seen them on another 67 390 GT but the PCV is in the middle of the valve cover? I can post some pictures if you would like me too. Here is a link to similar to what I have drivers side is the same but the passenger has the pcv in the middle of the cover! I will try to get a pic posted today of it. But I'm assuming if original it just took a short elbow hose to the PCV valve.

A valve cover with the PCV hole in the center of it is not original nor correct for your application from all the original ones I've owned and viewed over close to 40 years now
-
Ok well I will post a picture of them they definitely look to be ford vavle covers and not aftermarkets and we have another motor here with the same ones on it.

Here are some pictures.

I am with Jeff . I have never seen or heard of a variety like in the picture with a pcv placement in the center of the valve cover on a 67 Mustang before.
-
Ok well I was checking with you guys, But the driver side is the correct valve cover right? cause they didn't go to the powered by ford til 68 correct?
-
I found this link to a car that appears to have the PCV in the middle as well. They claim in their descriptions that the valve covers are original. This car is San Jose Oct. 66 build the one I am working on is SJ Sept. 66 build. Maybe it could be an early SJ thing? I'm gonna try to get in contact with the person that owns the car that the other motor is out of that has these valve covers to try to get the build date too.

No and I'm not sure where you got the 68 change date

Sorry but you can likely find pictures of all kinds of things with claims that they are original - you will have to choose what you believe but I thought the purpose of the thread was to ask us what we believed was original based on our experiences. I and FULLY comfortable at stating that I am sure its NOT a San Jose thing nor an early 67 thing ;)
As for the blue fastback - there are plenty of things IMHO that are not original with that car but that was not the purpose of the thread - Just one example would be the part number visible on the bottom of the front fender - which would indicate that the fender was replaced which in turn would indicate a repaint
You could always look at the dates on your valve covers but since they will not show the year. Here are just a few examples of San Jose 390's showing that side of the engine. Please understand there are other details in the pictures you should not repeat if your looking to go concours. Have dozens more

Hi Jeff,
The engine in question is from my car (and I was pretty surprised to see it discussed here online!)
I've had the car for almost 30 years now, and while I have no way to prove it, I believe both valve covers are indeed original to the car.
However, I do offer up a vintage photo for consideration. In the January 1967 issue of Car Life magazine, there is a photo of a 390 engine with similar valve covers, and the one on passenger side does appear to have the PCV hole in the middle of it (see attachments below)...
69SCJQ4 does bring up a valid question - when did the transition to the "Powered by Ford" valve covers take place?

Very interesting photo.It certainly helps give a different perspective. Thanks for posting . A lot of unusual features like the different looking battery heat shield and the clear zinc battery J hooks. I early car for sure.

Well this is the place to discuss this and we should all be open to do just that

Interesting article - one I had not seen before - so thanks. Magazine cars are often suspect given the many stories about the cars, the companies and the people who used the cars. Does seem to be a fairly loaded very early car with cruise control and such. The battery shield is an odd ball one - also seen in the very early 67 Fairlane in the shot below - from a Motor Trend article. In this example with all the Thermactor stuff its a little more difficult to see where its PCV is located.
(http://i44.photobucket.com/albums/f49/firetrainer/67FairlaneMTshot.jpg)
So do we have a detail that was on the first (week, month) 390's in 67? Guess we need to do some more searching.
BTW how does your cars vin compare to the first (lowest) San Jose picture I posted??
-

My car's VIN was a little later... let's just say my VIN is between 110600 and 110650...
The door tag date says 30J (Sept. 30, 1966) - but according to the Marti report, it was actually built eight days early on Sept. 22, 1966.
It was also a California car with closed emissions and the thermactor, but no A/C...
BTW - The engine tag reads:
390 67 7
6 J E 319 A

In reply #15, picture of the engine compartment.
Is that where the Curtis Wright speed control was located? In the middle of the firewall? The Perfect Circle version, isn't that one mounted on the shock tower or fender apron?

You can see it in the center. You can also see in both that the hoses have a double 90 with a straight PCV instead of using the 90 adapter style.

I only have the 75 version of the MPC which only list the part number for the Powered by Ford valve covers, but under PCV hose it lists C7ZZ-6A664-A for 67 Fairlane GT and Mustang 4/B before 10/3/66. So there is a rough change over date.

But that date does not seem to be supported by examples we've seen so far. The MPCs are not without some confusing information at time - example my copy shows 66 Mustangs equipped with 390 equipment listed ;)
Closest page I have is a 4/68 version showing the same right side valve cover (early - late starting 67 production) with a C6OZ6582-A preceding it and shown with an em/te hole
The left side valve cover is listed as being changed with the Level 8 change that year from C6OZ-6582-B TO C7OZ-6582-C. Given the other footnotes on other pages it appears that the change to L8 was the 10/3/66 date.
Notes also indicate that for other (non-chrome equipped) applications the left valve cover also changed but the right hand one stayed the same before and after the L8 introduction. This change in the valve cover appears to correspond with a change in the PCV grommet.
Got to ask did Ford use "left" and "right" in this application backwards from the left and/or right side of the vehicle? Hate using left and right when describing things on cars- always taught passenger or drivers cars during extrication course I taught to address the possible miscommunication
Unfortunately no nice detailed pictures for reference.
Still have the issue with the information maybe not matching with how the car may have been produced. Will try and find time to look through the TSB articles to see if there is a comment or note there to help the discussion
-
I realize that these are photos of a restored car, but I found a few shots in my archives the other day of a 390 '67 GTA Fastback that also had the exact same "center hole" passenger side valve cover and the "ribbed" driver side valve cover that my car has. These pictures were taken at a Mustang show 12 years ago in Vancouver, Washington.
I still believe these valve covers are the original Ford parts...
-
What does the air filter can look like? With horn, or with holes for air in.

Attached below is a shot of the air cleaner assembly that was on the car when I bought in 1983. However, I'm not as certain about it's originality to the car as I am about the valve covers...
BTW - There was another topic on this forum about a year ago with some photos of an early San Jose 390 engine that also had these "odd-style" valve covers as well: http://www.concoursmustang.com/forum/index.php?topic=2268.msg11649#msg11649 (http://www.concoursmustang.com/forum/index.php?topic=2268.msg11649#msg11649)

Here's another example of an early '67 390 engine without the "Powered by Ford" valve covers - the one's with the PCV hole located in the center of the passenger side cover...
