Exner Expert 10K+ Posts: 10171   Location: So. Cal | I didn't know that air cleaner was used on the Chrysler 300B. Why not just use the stock air cleaner? I guess they didn't think it flowed well enough? I assume that air cleaner used a paper element. The next question is, where can you obtain such a large element from? Probably better to answer that question first, before you go to the trouble to make one. I guess you could glue something together, but it would take a lot of them to fit that size.

Exner Expert 10K+ Posts: 10546  Location: Lower Mainland BC | . The photos below are from Gary R. who is (or was) in the process of restoring a 56 Dodge Coronet D500-1 race chassis (and engine) car. As for air filters, I helped Gary find some options including these: "Based on the photos attached) I chased some leads and *IF* the Outside Diameter of your filter is 16" (and 4" high), there are at least two or three options: https://www.knfilters.com/60-1641-round-air-filter-assembly https://www.amazon.ca/Allstar-Performance-ALL26022-Filter-Element/dp... https://pitstopusa.com/i-5083011-wix-racing-air-filter-16-x-4-flows-...

Exner Expert 10K+ Posts: 10171 Location: So. Cal | Knowing that the carb spacing on a 300B is 9", you can estimate the size of that air cleaner base. It comes out at 15", but notice that the lower carb hole is too small, so the picture isn't a perfect face on view. So my guess is around 15.5 to 16". Close enough to the 16" air filter element that Dave suggested. So personally, I would make it to fit that. Most likely it's the right size anyway. If Gary fabbed that air cleaner lid, I am really impressed. (Nascar 300B Base Dims.jpg) Attachments ---------------- Nascar 300B Base Dims.jpg (136KB - 68 downloads) | ||

Exner Expert 10K+ Posts: 10171 Location: So. Cal | Solidworks. There are a number of uses for it that it wasn't intended for, including proving difficult geometry theorems.  | ||

Exner Expert 10K+ Posts: 10546 Location: Lower Mainland BC | . Gary R's car is an original D500-1 car so the manifold, the carbs and the air cleaner set up are all real factory parts. I haven't been in contact with him lately so I do not know what the current status of the restoration is. I am pretty sure that the air cleaner element is a 16 x 4 as used by some Grand National race cars. | ||

Exner Expert 10K+ Posts: 10546 Location: Lower Mainland BC | Forward Look Frank - 2024-12-09 7:37 AM Thanks! If you have the opportunity, would you be so kind as to ask him for measurements or ask if I can receive his contact information? I would really enjoy learning as much as I can about this air cleaner. Thanks again for your time. I haven't contacted Gary since Dec. 2022 but I just did now, asking whether he is able to help you with your request for dimensions. If he says yes, I will give him your verizon email and you two can carry on. | ||

Exner Expert 10K+ Posts: 10546 Location: Lower Mainland BC | . I am not surprised by the 300C (392) and the 57 Super D500 manifolds having different dimensions. The 300B and 300C engines had/have a block length of 21.78 inches with bore centers of 4.5625 inches. The 57 Dodge D500 and Super D500 have/had a block length of 20.344 inches with bore spacing of 4.1875 inches. What is surprising to me is the 1956 D500 and D500-1 engines had a block length of 20.844 inches and a bore spacing of 4.3125 inches. I though that the 56 and 57 double-rocker 315 and 325 "hemi" engines have the same dimensions. Maybe it all works out that a D500-1 and Super D500 2 x 4 bbl manifolds fit 315/325s. ?? | ||

Exner Expert 10K+ Posts: 10171 Location: So. Cal | You're saying they made a different casting for a very rarely used dual quad intake in '57? I thought they just used the same one. My intake has the generator mount hole on it as well. If you end up making an air cleaner, make one for me too.

Carb studs are spaced for the wide pattern wcfb carburetors. Funny thing is offenhauser supplied the 4bbl intake in '54 for the royal 500. This is why I strongly believe the intake manifold was never listed in the parts manual. Somewhere in my files I have the offenhauser ad that says it's the same intake used by the factory for '57.

Exner Expert 10K+ Posts: 10546 Location: Lower Mainland BC | Forward Look Frank - 2024-12-12 10:18 AM Also, just for grins, I spoke with the offenhauser company owner a few years ago. He is 90% certain they cast the 56 D-500-1 for Chrysler as their mold for the '57 intake has a removable heat crossover, which would easily duplicate the 56 absence of a heat crossover. Who knows who cast what/when based on "memories".  Based on copies of factory memos that I have previously posted, the 56 Dodge D500-1 dual 4 bbl manifolds were cast by the Kiekhaefer Corporation, i.e. Mercury Marine, probably as a tit-for-tat favour between Carl Kiekhaefer (he of the dominant Chrysler 300 and 300B NASCAR 55-56 teams) and the Chrysler Corporation (and little brother, Dodge Division). Folklore suggests Chrysler/Dodge tried to make their own 2 x 4 bbl manifold for the D500 double-rocker engine but their castings were too porous and, under pressure for the Feb 56 Daytona speed week, they turned to Carl for help. (He must have loved that because he would know that they then owed him one (or two)). This: and this: REFERENCE thread: http://www.forwardlook.net/forums/forums/thread-view.asp?tid=75549&... | ||

Exner Expert 10K+ Posts: 10546 Location: Lower Mainland BC | . Frank: That will be great if you can somehow share at least some of the info regarding the D500-1 intake manifolds. Somewhere today, while poking around for more Purolator 2 x 4 bbl air cleaner info, I bumped into that suggested that Dodge again tried casting the 2 x 4 bbl D500 325 manifold but still had porosity issues and went with the Offenhauser manifold instead. (At least that is what I think I read). Gary R. did get back to me and said that he hopes to be able to provide air cleaner base, top, etc. dimensions in the next few days. He did provide me with three new (to me) photos that show factory "dints" (for clearance of the heater motor and something else). See attached. Gary also mentioned that" in the Hot Rod Magazine in the May1956 issue they did a feature on the '56 Daytona Beach Race. The magazine had a white '56 Plymouth Fury on the cover. Inside they had a picture of a -1 Dodge engine on a dynamometer with just the base of the air cleaner. There was also a picture of a '56 Pontiac engine with 2 fours and the air cleaner on it looks just like the Dodge air cleaner. I suspect that the Pontiac air cleaner and the Dodge air cleaner was made by Purelator. Ford had it's own air cleaner, Mercury used two small air cleaners, not sure what Chevy used, and as far as I know, a Chrysler 300B had 2 individual air cleaners." I have that magazine and I just scanned the page showing those air cleaners. See attached. I found the last photo of the Purolator air cleaner at the H.A.M.B. forum.

Exner Expert 10K+ Posts: 10546 Location: Lower Mainland BC | . Frank: Thanks for posting images of that D500-1 intake manifold blueprint. You are very lucky to own that. Thanks for sharing. I did hear back from Gary R. and I have forwarded his email to you at verizon. One of the things Gary said about the D500-1 air cleaner is "Measurements on the air cleaner - the bottom across is 18-3/4", the top is 17-1/4" and the height is 4-3/4". You can contact him for more info, as needed. | ||

Exner Expert 10K+ Posts: 10546 Location: Lower Mainland BC | Powerflite - 2024-12-13 12:22 PM Thanks for all the great information! I would like to see a blowup picture of the sticker on the front of the air cleaner. You can see it in the Hamb photo, as well as in the old magazine that Dave posted. I've never seen anyone put that sticker back onto their original air cleaner. I spent some time looking for the big Purolator air cleaner and the sticker. So far all I have found was this: (PurolatorCatalogImages_1.jpg) Attachments ---------------- PurolatorCatalogImages_1.jpg (149KB - 77 downloads) | ||
