Topic: 1967 GTA 390 Oil Fill Cap

[preaction]

I see, thanks Bob. Would the Scott Drake oil fill cap be my best replacement option then ?

The Drake closed emission cap is a very nice reproduction. As we have come to the conclusion on this thread one like it was used along with a push on to twist on adapter for a 390 GT with thermactor application. You just have to figure out which trademark style is best for your build of car . Early was the Ford in script in the oval or the Fomoco in block letters in the rectangle which was introduced later . I would guess  March 67 plus or minus as a change over but that would be just a guess based on Small block caps seen. I have no experience with BB application as it applies to a 390GT with thermactor.

I know this is an old thread and is dealing specifically with the closed system. I was wondering if anyone has a picture for a 390 GTA open system? Would this be the push on as well, or would it be a twist on?

Thanks

Got another question related to 67 VC caps...... The "Cookie cutter" caps that Bob showed in his first picture, what Shelby application are they ?  I thought they were only 67 427 Fairlane...... The pic shows what looks like a fairly new 67 Shelby, but it has CS Shelby valve covers.  Kinda confused. Disclaimer... I'm not a Shelby guy, more of a 428CJ guy.....

Thank's John

67 427 Fairlane shared more then a few engine parts with the 67 GT500. The closed emission cap (think thermactor system) on a 427 Fairlane is the same used on a 67 GT500 with thermactor.

The picture was from a vintage 1967 Popular Mechanics (if i remember correctly) article. Part of the article had to do with installing the over the counter valve covers, tuning and maintenance. That is why you see the replacement valve covers on a then 'new" car. I hope that ends the confusion.

Have pictures (a few so many 390's were played with  But they don't allow you to see how the breather cap on the drivers side attaches (with or without adapter) unfortunately its been difficult to find really nice unrestored/original 67 390 cars. Plenty of breather caps have been replaced as well as air cleaners through the years also

Did check the Cougar pictures (of which I have a few) also to check for you
