I've been searching for some parts, or ideally, the whole secondary air injection system for 225ci slant six. Does any one have one for sell and/or could put me on the right track to get one? I plan to use it on a '75 Duster, in order to make it a daily driver I need to pass Arizona emissions. Thanks!

What you SHOULD be doing instead is gathering and organizing people and undertaking a huge letter writing campaign, maybe find a few "unsympathetic" lawmakers with gigantic gas hogs and pointing that THEY even though their newer hogs are "legal," they create far more smog than the very limited driving your classic car is guilty of.

In other words get the law changed. I was astounded to find that even 67 model cars......WHICH NEVER HAD ANY federal (or AZ state) smog equipment other than PCV are required to pass smog!!!! in AZ
 
So, you are basically looking for the Air Pump, air injector pipe, hoses and brackets? Do you have any of the pieces (does your head have the AIR port on the back?)
 
I can't pull the whole rabbit (system) out of the hat (garage), but I do have the air injection check valve, brand new. This is the one that goes in the air pump's output line and prevents exhaust reaching the air pump. They fail eventually (every couple decades LOL) and then exhaust cooks the pump. Send me a PM if you'd like to have the valve.

Exactly how much of the system is missing, and do You even know? Here in PA, motor vehicles registered in a non-test area
have to pass a visual inspection of the emissions equipment, no matter what the year & model to pass State Safety Inspection. But if the vehicle is registered in a test
required area, and has less than 5000 miles one full year after the previous insp., We don't look at it at all and issue an IM sticker with an exempt insert!:realcrazy:
Luckily, they have started bumping the years up for not required status in test reqd. zones. If the vehicle is registered as an antique, no IM or safety insp. is reqd. Are You saying You have to retrofit an air pump? What IM testing
is Your Duster going to be subjected to? I'll be honest, I'm ignit when it comes
to when the EPA regs hit the A bodies full tilt. A lot of smog air pumps were
universal in nature, with mostly changes in adapters, valves, and pulleys. A
boneyard donor is the 1st step I'd take, check the parts cars forum here, many
of those era cars are stripped for mechanicals..................

Just stirring the pot here, but...
As a guy who was there in 75...
I don't recall air pumps being used until 76/77 and later. I do remember EGR valves being in place starting around 73 or so. Cats became mandatory starting in 76/77. I had a 77 Volare 318 auto that had "California emissions package" which, at the time, was no cat and an air pump, running 'regular' leaded gas. Not really certain which engines had that option available (360 that year did not).
Just saying, you may need to research this.
 
I might be able to help you...going to look at a 75 duster with 225 in it...going to put a 360 in it....pm me later today to see If I get the car.
 
Mine is late 75 build. I know there is a place on the head where an air pump would go, but never had one and I don't even think the hole is open in the casting.

1972 was the first year air pumps were installed on (some) Slant-6 engines.

Yes, 1973 is correct (1972 California cars got a really nasty EGR system that involved a "floor jet" in the intake manifold allowing exhaust right on in at all times with no valve control).

Cats became mandatory starting in 76/77

Catalytic converters have never been mandatory. Emissions limits were set that practically necessitated them on most gasoline engines starting in '75 in the US and '85 in Canada, but there is no law that says "Every gasoline-powered motor vehicle built after [date] shall have a catalytic converter". There are laws that say "Every gasoline-powered motor vehicle built after [date] shall emit not more than [amount] carbon monoxide, [amount] unburned hydrocarbons, and [amount] oxides of nitrogen, as tested according to [procedure]". Anyone's welcome to meet those requirements however they want. There are laws that you can't remove a cat from a car originally equipped, except to install a new cat. There are state laws in some places that if a car came with a cat it has to continue to have one.

No, sir. The '77 California emissions package definitely included a catalyst. So did the high-altitude emissions package. Some of the 49-state-low-altitude and Canada-spec '77 cars did not have cats.

Cars without secondary air injection had all the passages in the head, but a blockoff plate and gasket were installed on the port at the rear of the head.

I am certain your knowledge is more accurate than my memory. I just recall the dealership in Millington TN calling it the 'California Emissions Package' when I bought the car. Never trust a salesman. I just bought it because it used 'regular' (leaded) gas and I figured that this 'unleaded gas thing' was just a passing fad. (sigh...)
That is an interesting point about the cats, I have always thought of it as a government mandate.
 
Why? For any given octane rating, unleaded gasoline is objectively better than leaded in absolutely every respect.
