I don't think that's the case for the '55. Here is the underside of the cover. The bottom lip rests on the rubber seal. If the seal is not there it can only rest on the metal lip of the filter. Attach file:  PXL_20240523_174935636.jpg (459.83 KB)

It's what the cover rests on. Otherwise it's metal to metal.

Here's a picture of the air cleaner with what's left of the seal/cushion, which is flattened, cracked and partially missing.

The air cleaner for the single 4bbl V-8's appears to have a rubber O-ring about a 1/4" cross-section around the oil bath body which seals and cushions the interface to the cover. I'm not seeing this seal in the parts book. Does anyone know if these are repo anywhere or perhaps some bulk O-ring material would do the job?

Re: Oiling system history recap and update on the Oldsmobile oil pump conversion

On the upside, with the standard Olds Melling pump with stock relief valve spring (it came with a "high pressure" spring for optional installation), I've got great oil pressure on my formerly rebuilt V-8 and the lifter ticking is now gone. I did not opt for the high pressure spring as I expected it would not increase idle pressure but would boost the higher rpm pressure more than really necessary. I'm observing a steady almost 3/4 scale indicated pressure on the gauge at all rpm.
One surprise when I disconnected the internal vacuum tube to the vacuum booster is that it was mostly full of engine oil. The oil pump bushing appears to be tight, no play. I've not yet disassembled the original pump but am thinking the air ingress is from the vacuum booster rather than the shaft.

Packard for many decades employed a "floating pickup" combined with bypass oil filtration, to provide superior filtration with a single filter. Bypass filters filter out smaller particles than do full flow filters. The floating pickup is intended to pick up the cleanest oil as heavier particles sink, ensuring no large particle gets circulated.
I just replaced my pump several days ago with Jack's Olds kit. In addition to the rigid pickup, I also noticed that the pickup sits higher than the Packard original, like about an inch. I take this to mean you won't want to let your oil level get low or you'll soon be sucking air.

I have not found a working solution to this arrangement. Using the solid state flasher (which by itself improved brightness) I've tried several different models of equivalent to original polarity-insensitive LED bulbs and they appear to all have crossfeed problems through the lamps with the internal circuitry. For instance, even with just the fronts switched to LED the rear operation is all messed up, with brake, park and turn lamps not operating normally.

No need for a higher compression head with that big air pump on it. I don't think that will be much help with fuel economy.

I have found some iron heads from 22nd series and later -- at least three 288 heads, a 327 and a 356, plus one mystery HC head with no displacement indication. I assume HC is high compression, but oddly the combustion chamber is much deeper on this head. It also doesn't have the flat center ridge running front to back. Anybody have info on what this HC head is intended for?
 Also, any way to distinguish a 327MT vs. 327AT head?
