dual snorkel air cleaner housing

Hi Country:
Good question. I think you are referring to this line I wrote:
> But we also have this black dual snorkel for lean-burn hose...

I'm referring to the air intake hose that goes from the air cleaner to the radiator yoke.
1974-1975:
snorkel(s) had oval flair
no lean burn hose
radiator yoke didn't have fitting for air intake hose
windhsield washer reservoir on driver side (except for CHP spec when placed on passenger side to make room for horn to be mounted on driver side).

1976-1977
radiator yoke had fitting fir air intake hose
windshield washer reservoir on passenger side (always), to provide room for air intake hose from driver side snorkel to radiator yoke
single snorkel air cleaners had round flair (for connection to hose)
dual snorkels were only on cop cars (only on high performance big blocks, which were only available on cop cars)
For these, sometimes an orange dual snorkel w/ oval flair (no air hose) was used. And sometimes a dual snorkel was used that had a driver side ROUND flair (for connection to the air hose).

Notice how the black dual snorkel (in my previous post) has a round driver side flair.

Here are some pics of my 76 parts car showing the air intake hose routing and connection to the radiator yoke.



This means that a radiator yoke for a 74/75 is a different part number than that on a 76/77. A 76/77 can use a 74/75 radiator yoke, but won't have the connection for the lean burn air intake hose. And a 74/75 can use a 76/77 yoke, but will have an extra hole.

And note that a 74/75 passenger side windshield washer reservoir is mounted differently than a 76/77 passenger side windhsield washer reservoir. The passenger side inner fender is actually different, too.

> Is there another hose I dont see?
Yes, the hose that wasn't there. Sometimes I try to be tricky. :)

your friend in getting the hang of embedded pics,

Thanks, LV. I got a message today from an interested board lurker. We already have lurkers!

He pointed out that the the red car I show above is a 78 b-body, not a 77 b-body. It doesn't change our 74-77 c-body line-of-thinking, as I just wanted to use it as an example, but it is good to be correct so we don't get confused.

And, he said that with a 77 c-body high performance motor (which meant a 440 cop motor), the snorkel would never be the orange dual snorkel. It would be either the "Nick's Garage" driver-side round-connection for air-hose WITHOUT lean burn computer. Or it would be the Lord Vadus / red car above WITH lean burn computer.

The deciding factor was that 49-state cars HAD lean burn. And California did NOT have lean burn. California, at least c-bodys, at least high performance cop cars, NEVER had lean burn. They had their fair share of emissions stuff like the air pump and egr, but not lean burn.

Mopar documentation indicates that this switchover from dual orange snorkel "oval flair" to black "round flair" may have happened in the middle the 1976 model year.

So we have:
1974: without Leece Neville: could have narrow orange, or could have wide orange
1974: with Leece Neville: must have wide orange (narrow wouldn't fit)
1975: wide orange (they reduced down to a single dual snorkel model - narrow was obsoleted)
1976*: wide orange
1977*, california: black withOUT lean-burn computer
1977*, 49-state: black WITH lean-burn computer

* this switchover may be mid-year 1976, or maybe between 76 and 77.

Since the 1977 california high performance motor had an air cleaner housing with a round driver-side connection for fresh air from the radiator yoke, but did NOT have the lean-burn computer, I should not call that a "lean burn air intake hose". I should call it just a "radiator yoke cold fresh air intake hose".

Thanks everyone for working through these dual snorkel mysteries with me!

Does anyone know the proper routing of the dual snorkel air cleaner hoses?

I have these two photos:

But, as you can see, they are both routed differently.
Which one is correct ?

and it has the california only non-lean burn dual snorkel:

And here's a redone '77 Lean-burn (module removed) dual-snorkel of of a police Monaco that I intend to use on my car.

Currently, I'm using it on a 1973 El Camino since it won't fit on the 2-bbl carb in my Brougham.
