Hey guys! Actually my very first post. I need some help identifying this connection off thunderbird 390 air intake manifold. I picked it up off of a pick n pull and still trying to figure out what the connection is on the rear end of the manifold. I think it’s the brake booster? Not entirely 100%. Thanks !
C = 1960s, 4 = 1964, S = Thunderbird, E = Engine engineering group.
The date code shows as 4B13, decoding to 4 = 1964, B = the 2nd month, February, and 13 the day of the month. So Feb 13, 1964, an item for 1964 production.
One (top or first photo) with what I believe to be the tubing and PCV still attached to that rear port. Scroll down for a view under the manifold. Some of that shielding is keep liquid oil out of the PCV port. Does yours have it? http://www.mustangtek.com/Intake/C4SE-9425-A.html
Brake vacuum would have come from the port just behind the carb pad on the driver side.
Do you have a plan for it? Heavy little fellow.... but as long as it's "sound", a decent manifold.
85e150 is correct. That's the early connection for the PCV system. Prior to that, Ford (like everybody else) used a road draft tube for crankcase ventillation.
