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


Front block that attaches the U shaped vacuum balance/transfer tube at the front of the intake - Purple arrow




Rear shot showing the rubber hose that connects the Thermactor diverter valve to the PCV T near the PCV - Bright green arrow




Overhead shot of the rear of the system.
Yellow arrow - shows the rear attachment point and hardware for the solid vacuum balance/transfer tube
Bright green arrow - the hose to the Diverter valve to PCV hose
Dark green arrow - rubber hose that connects the balance/transfer tube to the T near the PCV



Couple additional angles




As always - 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

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.

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


7R01S1045xx



7R01S1323xx



7R02S14185xx



7R01S2121xx



7R01S2257xx




Please don't believe everything you see/find on the web!!
