The rubber hose that  comes  off the vacuum advance, where does  it  attach to, to get vacuum, I am having trouble finding a  picture,

Try the 67 shop manual.

See attached pictures. Don't pay any attention to the insulated choke tube ; it is just laying there.

Hope this helps. Note that this is on a 289 2 bbl.

I looked at the shop manual - general engine area, 390 engine area, and ignition (distributor) area but did not see anything.

I also looked at the vacuum manual but that does not cover the engine advance system.

Keep in mind that Bob's picture of the 289-2V is generally good, but the 390-4V will not be exact.

Also if you have the temperature based vacuum switch that adds to the complexity.

Can you confirm the engine that you are asking about, and let us know if you have the temperature based vacuum switch (aka tree) or not?

The engine is a 390 in a 67 gta,thermactor car,I don't  have the tree type vacuum  fitting, I thought it was going to be at the rear at the bottom of carburetor which is a Holley 4150  C70F 9510 -D

I have a fitting directly behind  distributor  with  2 barbs on it one goes to the anti backfire valve, could the other  barb be for the vacuum advance

Add the "S code" to the title since it makes a difference in this setting and question

One of the attached should cover your situation.

Yes that's  the schematic I am looking  for,thanks for your help,I looked again in shop manual, and on page 10-84,fig2,it shows a port on the metering block for vacuum  line connector,next time I will  look harder

Looks like the middle one. Others don't apply 


Picture for one of the applications (Manual - thermactor - automatic or combination) makes a difference



And for the other

Those drawings are from the "67 Ford Products Engine Assembly Manual". I recommend you get a full set of assembly manuals for your car.

You got it. I think that it is called ported vacuum, on a Ford numbered Holley 4150.
