Re: Proper air cleaner for 352 V8?

Guy -

You might be interested in my post (#10) in the recent "batwing" thread, which I composed in response to PackardV8's attempt to classify the 55-56 air cleaner styles into four categories. While discussion in that thread went a bit off-topic, from a simple "for sale" posting that mis-applied the term "batwing" (which was later removed), it brought some good info to light.

My attempt to clarify was based on the parts book listings, plus ownership of several '56 models, plus one '55 Patrician (long since sold), which were in relatively unmolested, original condition (save for exterior repaints in non-authentic colors on the sedans and '56 side trim on the one '55). However, I don't have that much experience with the Clippers - except for the '56 Executive, as a derivative. Fortunately, other members have provided images (a couple even with part numbers) of some of those other units, in the first page or two of this thread. (I'm still not clear on the Houdaille unit for '55 Clipper Custom.)

Now, I don't have a sample part, here, to confirm that the parts book's Gr. 9.10343 refers , specifically, to the gasket that goes between the air cleaner and carb, but it shows the same one, P/N 473070, for all chassis with 4-bbl. carb(s), which raises an eyebrow. Although I've never taken any measurements of the Carter WCFB and Rochester 4GC, I wouldn't be surprised if the respective air cleaners could be cross-fitted. However, the Carter WGD 2-bbl. used with 5640 chassis (body 5622-5642-5647), has a much smaller throat. (The '56 Clipper Super with aftermarket, trunk-mounted A/C, cited earlier in this thread, must have also received a carb upgrade, then.)

Meanwhile, you might also enjoy a look at the BATWING AIR CLEANER GUIDE, which I originally cited in the "batwing" thread. Though penned from the perspective of a Pontiac enthusiast, with no reference to Packard applications, it shows some significant differences in what casual observers might consider to be a single design. It's interesting that GM didn't serve up the answers on a silver platter, but enthusiasts of other brands have to practice a good bit of automotive archeology, as well.
