Topic: 65 Hipo Aircleaner

Is this a factory Ford air cleaner or a Repo? Hard for me to tell but I am leaning repo because the nipple on the bottom does not look quite right.

Hard to say.  Keep in mind that unless your '65 has a California DSO that it would not have had the hose connecting to the oil filler cap.  There are a few versions of the bases, some with or without the nipple.

By the color, it's a 66 air cleaner, and with the fitting, a California requirement for smog (PCV type), plus some other states as well.

Lid contour looks like one of the nicer repos IMHO.  Specifically, noting the difference in contour between points 2 an3 on the tape in attached photo.    Another test would be to weigh the lid - originals quite a bit heavier.

Is there a thread with reference for the '65 states that used the closed oil breather and '66 with emissions?

Just state law.

Actually from lid sticker it is a 67 GT350 . My guess is that it was a repro . It would have to already be restored if it was original because a couple thing come to mind. Number one is the chrome is too good on the bottom side compared to typical plus the metal is too perfect with no imperfections (wavyness). The same with missing black out paint details on the base. Another thing more circumstantial is that it is a typical mistake to use the 65/66 closed emission base on a 67 GT350. Actually the typical 67 GT350 did not use  the larger nipple base. The typical 67 GT350 used a open emission cap and a base open emission base.  Only a very small fraction of 67 GT350 production had thermactor which used the larger nipple base .    FYI all and 65 and 66 GT350's used the closed emission caps and larger nipple base regardless of state.

I do not know of any states other than California (the pioneer in '66 for emissions) and would be interested to know if there were in fact any other states in 1966 requiring the closed oil breather and/or T/E control.

Believe New York and possibly one or two other regions if I recall the documents and laws of the time.  Think their also shown/listed in the Emission manuals printed in the 60's and 70's

Did these air filter housings have a year, month stamp in the base ? Such as 6C.

Yes the bases were typically dated in that fashion.  ALWAYS ??

Typically but not always . 5A and 6A are the most common 65 and 66 date codes from what i have observed.

[jwc66k]

5A and 6A are the most common 65 and 66 date codes . . .

There are two stories about date codes 5A and 6A:
1 - Ford ordered a large quantity of air cleaners on those dates, but over estimated the usage and did not place another order for a long time;
2 - The fabrication drawings indicated markings there and the example was 5A and 6A so the numbers were stamped that way, sort of defeating the date code philosophy.

Believe that they were only stamped out when the supply dipped then the stamping machine was changed over to another application rather than having dedicated (for each and every type of panel) Seems that for their Jan 65 run they just figured they would sell more in the up coming months.

Anyone recall seeing a base stamped with a "4" for the early 65 cars?

Here are three dates 6A - 6C and 7C

[Bartman]

I have the original air cleaner on my early Aug 64 K code and there's no stamp at all on the base. Maybe the early bases weren't stamped?

They were typically date stamped but not always as posted in reply #11.  I have seen a pattern of more of the open emission type (without the large nipple) missing the date stamp then the closed emission type (with large nipple) .

From what I have observed of original air cleaners / cars, scenario #1 fits very well.
