The air in the air cleaner assy will always maintain about 120 degrees F.  This is once the exhaust manifolds get hot, which takes less than a minute.

Keep in mind, this is for optimum fuel control and emissions with a carb.  That does not mean it is always best for performance.  A colder air supply will create a denser air volume, and thus more air into the intake and into the cylinder, which in turn produces a bit more power.  It may not be noticable in street use, but might show up on a dragstrip.

Well I finally got round to fitting it. GOOD NEWS... the
two vacuum controlled flaps still operate. BAD NEWS... I
would have thought that after driving around for 15 mins
it would have warmed up enough to open the flap it
controls, but no so I swapped the hoses over
which attach to the sensor just in case it makes a
difference, and still no joy ...if I touch the
"plunger" in the sensor ever so lightly the flap opens
nicely, but on taking my finger away it closes again.
Is there an easy way to test the sensor's operating
properly / at a correct temperature (whatever it is) ?

On the plus side, as it is around 6 degrees C here
currently (winter has arrived) - that's around 44 F
in your talk - she does seem to be smoother on start
up from cold !

AHHHH the land of the long white cloud.  CeeDee, do you need your car to be totally original?  If not, get rid of that original air restricting can on the carb and put a Holley 600 on with choke and full flow air cleaner, then just wait for the engine to warm up.  I believe you can do that in Un Zud and remove all the anti-pollution crap while you're at it.  You'll then have a car that both looks good and performs like crazy.

P.S. Just don't drive too fast or you'll run out of road and end up in the drink.

Well I'll be, a for real ocker ON C3VR !

Gidday mate. ( sorry, couldn't resist !!! )

Car is already clean of all smog stuff... air pump is
gone altogether, and as far as I can make out anything
to do with emissions has been removed or disconnected,
even the EGR is disconnected.

So I'm just tinkering with bits that seem to do no real
harm when they're connected. Not looking at all to
restore to original.

However I kinda liked the idea of having warm air
feeding the engine while it's cold. Not particularly
stressed about it at all though...

P.S.
Northern Territories... your Vette wouldn't make it
between gas stations out there would it ????

Always nice to hear a Kiwi and Oz-man banter back and forth.  Such amicable animosity!  Just never thought I'd hear (see) it on the C3VR forums!

Goodonya mate!  You both just need to sit down and discuss it over some tucker.  I know, I know, Vegemite (spread on anything) for the Oz-man!

... Vegemite just happens to be my number 1 toast spread
too... I'm sure we invented the stuff here in NZ

Kiwi Chris

I onlhy just make it between gas stations but I can drive as fast as I like.  Vegemite invented by Kiwis?  I don't think so!!!

Only problem is, the bloody company is owned by the yanks now just like Arnotts

I bought a 1982 just recently.  I noticed that the air cleaner louvers were not closed when the car was cold (or not running).
