The 2 bbl air cleaner I have does have a snorkel and a thermostatically controlled hot air tube as well. I suppose an open element air cleaner might get more air but it will also collect more dirt and the air it does get will be pulled directly from the engine fan air stream which flows across the hottest part of the engine bay. I believe a snorkel type air cleaner is the best route to go. It could be further improved by extending it with a tube of some sort through the radiator support or inner fender to draw in colder outside air. |

The standard pie tin would have a snorkel, like described above, and would help warm the car up faster, then draw cooler air from the battery area vs. the whole engine bay. You can use one of the small block/318 air cleaners if a super six version is not available (or use one of the open air element, or an unsilenced version/no snorkel used on the 60's cars)...There was an option on the F body cars that ran a flexible tube from the air cleaner snorkel to a plastic fitting mounted in the drivers side fender, drawing fresh air from behind the headlight,after the car is warmed up. The plastic assembly isn't formed for other bodies so you'd have to cobble something together. The pietins for these have a round end on the snorkel and a clamp to hold the flex to the assembly (kind of looks like an oversized version of the 'heater hoses' under the dash...) -D.Idiot |

Actually, ducted cold air induction as you describe was standard equipment from '76 up on most Chrysler Corp passenger cars except the A-bodies. Some of the air cleaner housing snorkels had a formed round mouth as you say, and some of them had a regular oval mouth. In either case, the plastic duct had a formed end that snapped onto the end of the snorkel, whatever its shape.

added info. . . . . . . . . i'm working with an A-108 van. i have no real place in my engine cavity to find "cool" air. i also suspect the larger pin plate air cleaner won't fit in the doghouse on a /6. maybe i should just attach a conduit to the carb throat and mount an air cleaner on the belly pan in front of the radiator? D~~~! |

Yeah, that's a horse of a different color for sure. If you've got room to run the plumbing that might work out. It would be an interesting experiment anyway. |

B series vans have an offset super six air cleaner. |

I wonder if something like this would get enough air to your BBD? http://www.go-kat-go.com/chhotrodairc.html I've been having the same dilemma for my air cleaner choice on my super six (granted I'm not limited to size like you) I just don't like the look of the stock snorkel style. |

So do AMC/Jeep vehicles with the 258 six-cylinder engine. See here.

I also suspect plumbing something up for the stock 90's Jeep Cherokees would be OK, since they use a rectangular air cleaner/'box' near the front fender (driver's side) that's connected to the throttle body via a plastic flexible tube... (I suspect I may do this when I get things setup for the EFI Hpak, as I want to control the hot air intake for engine warm up a bit more, than just running an aftermarket open air cleaner...)-D.Idiot |

The unsilenced air cleaner from a BBD equiped 273 will fit cars and trucks, don't know about A100/108. I have them on 2 '68 Valiants and a truck. Since the top is the same at the '68 1bbl top, the motor looks stock on the Valiants. The '67 tops do not have the the breather hose nipple, the '68 top does. I think '69 tops are the same as '68. '70 air cleaner used the silenced snorkle, maybe one off a BBD equiped 318 will fit the '70-up cars and still keep the factory stock look. |

Check that -- will fit some cars. Your '68 Valiant has a lot more hood-to-carb clearance than, say, a '62 or '63 or '64 A-body.Quote: the top is the same at the '68 1bbl top
Mmmm...it has a similar general appearance, but it's definitely not the same. The '63-'69 1bbl air cleaners had a lid that also formed the sidewalls of the air cleaner assembly, with the baseplate serving only as the base and silencer lip. The 273-2bbl air cleaner you're talking about has the sidewalls as part of the baseplate, and the lid is just a lid.The 273 air cleaners to look for are the '66-'69 items. Earlier than that sits higher, and uses a clamp-band style attachment to the carb air horn, rather than the bail and wingnut. Later than that ('70+) uses the thermostatic snorkel, which is a good functional upgrade, but if you're trying for a stock '60s look it doesn't belong. All of these are silenced air cleaners; if you want unsilenced, remove the baffle from behind the snorkel (really not worth doing; leave it in place.) And remember to install the cleaner with the snorkel facing across the valve cover, not forward, otherwise you can get a strange surge/hesitation when transitioning from cruise to acceleration. This bizarre driveability quirk was the subject of a TSB in '61, saying, in a nutshell "To cure hesitation when accelerating from part throttle cruise, make sure the snorkel is positioned across the valve cover and not pointing forward". I tried it with a '66-'67 round-snorkel 2bbl air cleaner I had on my '65 when it was equipped with a 2bbl, and sure enough: Snorkel forward = hesitation on part throttle acceleration, snorkel across valve cover = no hesitation. My guess is the ram air from the forward-facing snorkel + forward motion of the car screws with pressures in the carburetor's venturi when the throttle is opened. The breather inlet air hose nipple is, as you say, present on '68-'69 cleaners. It's also present on '64-up California cleaners. |
