This post: bluesmobiles.proboards.com/index.cgi?action=gotopost&board=cops&thread=90&post=253got me thinking about dual snorkels again. That 1976 police Fury has our beloved orange wide-angle dual snorkel cop air cleaner: I think we decided that: orange narrow angle = Only available in 1974 without Leece Neville alternator orange wide angle = Mandatory for 1974 w/ LN alternator, also used for 1974 w/out LN alternator, and 1975+ but what about the black dual snorkel with lean burn hose attachment? It seems there are two of those models. IIRC, Lord Vadus' is from a 1977, and has the lean-burn module on it. It looks like the air cleaner housing on this 1977 b-body Monaco: LV, do you know if yours was from a b-body, or c-body? 1977, right? But we also have this black dual snorkel for lean-burn hose, but without the lean-burn module: from www.nicksgarage.com/aircleaner.htmIIRC, on BBC AZBlues explained that a 1976 would typically have a lean-burn ignition setup, and my 1976 Gold partscar Monaco did NOT have the ignition module on the firewall (because it was in the lean-burn system in the air cleaner housing), but that Bluzman's 1976 ex-police Monaco from TX DID have the ignition module on the firewall (because it had a standard orange dual snorkel air cleaner without the lean-burn module in it). It makes sense maybe in 1977 emission regulations forced cop cars to also have lean-burn, hence LV's dual snorkel with module built in. But what about this black dual snorkel with lean-burn attachment WITHOUT the module. Maybe that's a super rarity. Instead of using that they could have just used an orange dual snorkel. Anyway, thought to kickoff a dual snorkel thread and put down some thoughts. your friend in kickstarting the memory, arthur

The only hoses I see are for the breather on the left, and the silver hose that runs to the exhaust manifold for the risers in the snorkels, on the bottom right. Is there another hose I dont see? -zac

Arthur, On the black dual snorkel, witch hose are you talking about? ... Is there another hose I dont see? 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. Above = 74 Marin County Above = 76 parts car Above = 74 Marin County, attachments to reservoir looking from driver side towards passenger side Above = 76 parts car, looking opposite direction, passenger side towards driver side > 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, arthur

Lord Vadus' is from a 1977, and has the lean-burn module on it. It looks like the air cleaner housing on this 1977 b-body Monaco: This is correct; mine was off of a 1977 Monaco Police Interceptor. LV, do you know if yours was from a b-body, or c-body? 1977, right? It makes sense maybe in 1977 emission regulations forced cop cars to also have lean-burn, hence LV's dual snorkel with module built in. Mine was from a b-body that was virtually identical to the car in that picture. I've read that all applications of the 440 were running the lean-burn in 1977, but I can neither confirm nor deny this. Though, I do know from my 1977 Chrysler New Yorker that there were other air cleaner options for the year; notably a 440 lean-burn single snorkel air cleaner.

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! /arthur

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 ? .

I think the bottom pic (on the tile) is correct. The 1974 dodge chassis service manual, page 25-8, has this pic: your friend in bluesmobilearrific hose routing, arthur

When I started this thread, BBC was down so we didn't have access to our old dual snorkel info. Today, Country Bunker wrote about getting a decal for his dual-snorkel air-cleaner housing bluesmobiles.proboards.com/index.cgi?action=gotopost&board=owners&thread=46&post=4045and it seemed like a good idea to refresh my memory of what dual-snorkel info we had on BBC: www.bluesbrotherscentral.com/forum/topic/8176-angle-between-440-dual-snorkels/page__hl__%2Bdual+%2Bsnorkel__fromsearch__1Sometime, we should capture all the good info here (such as the reason for the narrow angle air cleaner housing and the wide angle air cleaner housing). But for now, I include the pics showing various decals. above, 74 king-of-the-hill above, 74 king-of-the-hill above, 74 marin county above, 74 RCMP mbmopar from s178.photobucket.com/albums/w244/mbmopar/above, 74 buffalo collection above, 74 400 motor (car unspecified) www.allpar.com/mopar/b-engines.htmlabove, 74 440RULEZs CHP above, 74 roadrunner 400 www.nicksgarage.com/aircleaner.htmabove, 74 400, car unspecified www.dodgecharger.com/forum/index.php/topic,6366.0.html above, 1974 400 and 440 4-Barrel, car unspecified www.nicksgarage.com/aircleaner.htmabove, 75 volo www.bluesbrotherscentral.com/forum/topic/6128-selling-usa-1975-monaco-volo-bluesmobile-illinois/#entry82105above, 76 cop car from TX to bluzman in maryland www.bluesbrotherscentral.com/forum/topic/9714-sold-1976-dodge-monaco-parts-car-maryland/#entry105147above, 76 MHP bluesmobiles.proboards.com/index.cgi?action=gotopost&board=cops&thread=410&post=23271977 b-body Monaco referenced here www.bluesbrotherscentral.com/forum/topic/8176-angle-between-440-dual-snorkels/#entry111051

To recap, a 74-75 cop monaco with a 440 would have a dual snorkel that was either: narrow-angle: That could be used if the car did NOT have the larger Leece Neville alternator: or wide-angle that could be used on anything: I believe that all were factory orange. Were all dual snorkel Mopar air cleaner housings factory orange? It seems that Furys like blue. Here's a narrow-angle unit: from bluesmobiles.proboards.com/index.cgi?action=gotopost&board=sedans&thread=287&post=5519Please tell me that's not a factory color. My Fury had a non-orange housing: but I believe it was originally orange and had been repainted. The entire engine was a cobbled together piece just to fill the hole in the car for sale. your friend in keeping the color, arthur

Info on the air cleaner housing OSAC valve (not unique to cop cars, but this seems like a good thread to post the info).

This is the one I got! I need to know what hoses go where, or if I should even hook them up. The vacuum hoses to the snorkels seem to open some trap doors, to act as a choke? Not sure what the valve on the front left does. It says carb and dist on the 2 ends of it, don't want to hook them up to the wrong things. Might just take it out since it's probably just rusty or plugged up anyway. I have an 850cfm Thermoquad if that helps. Edit: Upon further inspection, one trap door seems to close the snorkel and the other seems to open for cold air intake? Question is which vacuum line do I hook to it? The back of my carb only has 1 hose I think but 2 or 3 plugged outlets. Would it matter which one I plugged it into or does it hook to something else? The valve on the front is an emissions valve, so I doubt that'll help performance. (Correct me if I'm wrong.)

Does anyone know for sure if this is missing something from the top? I keep seeing stock ones like this, but then I bought an after market one that is a little different and it has a piece that clips on top like this vvvvv
