Was The Hudson 7X Engine Ever Advertised?
![[Deleted User]](https://openforum.hetclub.org/applications/dashboard/design/images/defaulticon.png)
Did Hudson do any print advertising on the 7X? Does anyone have any Hudson 7X advertisements outthere? If so, I'd love to see or get a copy of it. Niels

Hello,
I am not an expert but i have a fair collection of old Hudson Addvertisments from various magazines from the era.
I never seen an Add specifically mentioning the 7x motor. The Add's instead refer to Hudson's durabiltity & endurance resulting in Winning many Races. I may have seen one mentioning using 'Severe Usage Parts'that are available to anyone through a local Dealer.0 -
If anyone would have such an ad or had seen one, Sean (51hornetA) would be the guy to ask.0
-
I've seen & collected a lot of HET for over 40 years & have never seen a retail ad for the options Hudson offered, obstensibly for police cars, LOL.
I believe I have all the original stuff on them, or copies I got from Jack Miller, and the parts were not available to the public 'til Aug. '53 as I recall.
The only performance option offered publically was Twin-H Power but not sure if you'd include it in the 7X engine package.0 -
The only reference to 7X engine kit (#309395) I have found is in the Hudson Master Parts Catalog, 1948 thru 1954, Section "Z". This is a separate section of that catalog that lists all the "severe usage" parts that were available. Did you guys know that there were even a "Special Order" AC Alternator available for the entire line of cars at that time? It is amazing what you can learn from the Master Parts Catalog.

Jerry - the most interesting info is from factory sheets sent out to the dealers with the latest SU offerings.
The biggest "turmoil" was when the factory put the "flat lobe" high performance cam in the new '54 which boosted the h.p. from an advertised 145 to 160 BUT became a service problem as it burned up timing chains SO engineering came out with several new cams for the production models as well as offering several different SU cams, the last & best being the "211040" which was it's parts #.0 -
If some of you are interested in this info I can dig out these factory sheets & perhaps have Ryan post them to his site so you could read them, perhaps copy them - let us know.0

Pete:
I have seen print ads that advertise a SKELETON engine for Hudson. It shows the Block on one of those round tube engine stands. Am I remembering trade or Hudson internal publications or was this shown in some of the mechanics mags etc?

You know me - I'm always interested in Hudson material I can scan for the web site.

Right, but believe that was sent out to dealers. What I thought Ol meant was advertising to the general public.
I worked at a Hudson dealership when in h.s. part time in '53 & '54 in a small town in no. Ind. As I recall our best customer owned a bakery in a county seat (much bigger, Warsaw, Ind., LOL) where there was no dealer. He was a little guy but wanted "the hottest car in town" & would frequently drive over in his 2 tone brown '52 Hornet cp. to get the latest SU head, cam, carb. modifications, or whatever ordered & installed as we had a top mechanic who was willing to work after hours on his car.0 -

Yes Pete, how well I remember the warranty work on all the 54's we sold, changing camshafts & timing chains. By the way, I beleive the part number you referred to above should be "311040". I would be interested in seeing those service notices you talk about above.

The flat lobed 54 cam was a problem. It also was noisy and as a result a lot of them were called back and reground. I've been into a lot of 54 engines that had 309742 (flat lobe 7X cam #) part number but had been reground to regular 54 specs.0
-
Jerry - right, LOL, 311040!
As were in this vein of discussion, in the '80s I met a guy who lived in the San Fernando Valley near me who had a '54 H cp. & was like the previously mentioned baker exc. that he was an engineer at one of the local aerospace companies. After he retired he decided to stop messing with his Hudson & sold the car but the buyer didn't want to "pony up" for the parts so I bought those.
He made many adjustments with carb. types, timing, cams, etc. (had got a lot of stuff from Clifford) & had all kinds of little notes on what had worked best. The most interesting item I got from him was an almost new 311040 cam still in it's original factory tube. I kept it for a long time, but as never into high performance stuff, sold it when I left Calif., I think to my best HET pal, Buzz Stahl whom I'm sure still has it.0 -
Yes Pete i still have the 311040 cam. Last year Ivan & I collected as many Hudson cams we could find, Hudson production & after market & had them run on a cam profile machine at Mega Cams. The 311040 turned out to be the best cam Hudson ever made and it also beat almost all the after market cams. Ivan has all the results.0
-
Howdy Buzz, didn't know "dover1" was you!
Yep, thought you'd keep that cam.
A few months ago posted a pic of that 2 pc. '34-5 head I found at Dearborn & gave you. Did you or Ivan ever try it, do any compression checks, etc.?
The '50 C8 cp. done now?
Trust you'll be at Pontiac?0 -
Yes Pete I thought someone should give recognition to Hudsons trucks so dover1 is my user name. I have never cc,ed the two piece head so I do not know compression ratio but I think it is given in the parts manual. The 50C is stripped of paint and waiting till I return from vacation in Pa. then off to Tims for new black paint. Pete the car had no rust, not even the rockers. Ihope to have it at the national. I am using the Edmunds intake manifold, Edmunds head & Railton exhaust manifold. I think period speed equipment will look proper on the car. Hope your trip to Tahoe was fun.0

The 7x and S/U Options must have been advertised at one point because over time different people (outside the Hudson Club) have asked if I had the 'special' Hudson motor. Perhaps S/U options were communicated well at the time of car purchase...0 -
Ol - I think the answer to your query would be Hudson's successful racing which would bring those interested in performance to the dealer to see if he could get the parts Thomas, Teague, & others were using as they had to be available to be legal on the race cars.0
-
I was curious about the 7X advertising because I would have liked to had some colateral materials to display at car shows, etc. Looks like I'll put some info together from Ken's website and a couple other sources. Thanks for the info. It was an intereseting thread.0
-
Buzz - that would sure be great if you could bring it to Pontiac!0
-
The "Severe Usage" performance options group is probably similar to the COPO performance options from Chevrolet. You had to inquire at the dealerships, they were never advertised. Most of the COPO performance options were unsuitable for daily driving.0
-
Also in this vein, & as most of you probably know, you could not order a new Hudson with any of these options (other than Twin H) installed on the car - they were put in the trunk to be installed by the dealers.0
-
Did you know that a young Engineer for Hudson named Vince Piggins actually created the S/U Options by attending the early NASCAR Races to evaluated the componets for necessary improvement to be competitive.... Refer to the NASCAR Thread with Vince pictured with Herb Thomas & Smoky Yunick...
Vince later, after Hudson ended racing was hired by Chevrolet to improve the performance of their (then) new V8 while under a GM race Ban which he cleverly did similar to his Hudson Days by creating Hi Perf components under the guise of Off Road' Parts..... Vince later implemented the Z28 Performance Car...0 -

Here again comes the 7X engine. Hudson never made or sold a 7X engine. They were built by the guys racing Hudsons. You could order a SU block which came with the car, 0.030 overbore and 0.010 undersize mains and rod bearings. The SU cam came with the car but was in the trunk, the dealer had to install it. Hudson Motor Car Co. was then off the hook. SU chassis parts were standard on overseas cars but not on cars delivered in the USA. You bought them from dealers and installed them yourself. The race engines were called 7X but built by the big boys. I built many and sold them to guys racing Hudsons on big and small tracks. I also sold Hudsons as I was a sub dealer for a Hudson dealership in Waterbury, CT.Did Hudson do any print advertising on the 7X? Does anyone have any Hudson 7X advertisements outthere? If so, I'd love to see or get a copy of it. Niels0 -
I hate to refute an icon but Walt is incorrect. I'm scanning "Parts Merchandising Bulletin" dated "8-3-53" to Ryan which specifically offers dealers the 7X engine.
The 1st para.: "Hudson is pleased to announce the immediate availability of the...NEW HIGH PERFORMANCE 7X SKELETON ENGINE ASSEMBLY.... adaptable to all 7A, 7B and 7C Hornet Models." (capitalizations there's).
It then lists all the parts inc. with it, gives a parts # & a price so they were not "built by the guys racing Hudsons" & Hudson both made & sold them, and as "7X" engine short blocks.
I'm sure Ryan will make a post with this & perhaps other 7X related info I send him.0 -

Addenda: the "TWIN EXHAUST MANIFOLD AND PIPE KIT" offered "6-16-52", list price $50 & "Dealer Net - $30" LOL!!!!!!!!
Twin-H 1st offered "8/1/51" & consisted "of an aluminum casting".
Part #307559 was offered "May 8, 1952" as a "Severe Usage Kit" for the front end.
A Bulletin dated "1-2-53" offers "New Rear Axle assemblies and Hub & Bolt assemblies for SEVERE USAGE - - " with ratios from 3.07 to 4.55.
Actually a Bulletin dated "1-15-53" states that it is a supplement to a Bulletin of a week earlier "announcing a new extra high performance Skeleton Engine Assembly and a new camshaft" but it does not list the parts inc., just a parts # & price.
In Mar. of '53 a "UNUSUALLY SEVERE USAGE PARTS KIT" was offered consisting of various front & rear axle parts.
For a short period of time a 28 gal. gas tank was offered.
"January 21, 1954" a letter to Zone & Divisional Managers states: "For your information, the 7X Skeleton Engine Assembly, C 309395, has been temporarily disqualified in stock car racing, sanctioned by AAA and NASCAR".0 -
Pete, Do you know if anyone has ever see the aluminum Twin H intake manifold. I have ask many members here on the left coast and no one was ever heard of it.0
-
I'm also scanning to Ryan the bulletin in re the 311040 cam, previously discussed. It is referred to as "NEW SUPER HIGH PERFORANCE CAMSHAFT".0
-
Lastly, at least for now, am scanning to him a letter to Zone managers from "Mr. W. S. Milton" dated Nov. '53, subject "SEVERE USAGE MATERIALS", complaining that dealers aren't paying attention & continue to order cars with SU parts factory installed.
It's a kind of funny letter in that he grouses about dealers not paying heed to Parts bulletins but also explains why, etc.0 -
Buzz - I don't recall ever seeing one & I think shortly after that they changed to cast iron as later parts bulletins about them DO NOT say they are made of aluminum.0
