Not mine. Saw this on evilbay and looked at the VIN. It's an X code Supreme that appears to be in decent shape. Thought someone may be interested.
72 CS with X code

Mr442

I thought the X meant it was a 455 W-30?

TenMidgets

Does the X code represent a 455 4bbl?

Allan R

I thought so too. That would be the L77 engine, but it was only available with the W30 Cutlass Supreme convertible. I'm wondering if this wasn't a special order car or something?
Yes, both X and U were used for 455 codes. But the X was special for W30's.

11971four4two

My guess is or something
It is a 350 car in the description pot stirrer

Is the X in the right place to signify W30 and/or 455? The 72 VIN numbers are like a foreign language to me.

Early, early production.

jensenracing77

i think something smells fishy. if it really was an X it couldn't have had A/C either in 72. maybe i am wrong but i don't think this car is right.

Allan R

Look at the engine photo - IMO it's too wide across the manifold to be a 350. I'd be more inclined to believe the ad if they had said U code. Maybe I'll send them a question about this for clarification.

The X is in the right place for the engine identification; and I'd guess you're right about early production. Likely September 71?
3J57 = Olds Cutlass Supreme 2dr coupe X = L77 W 30 motor 2= 1972 model year M = Lansing; home of ALL W30 production 100753 you know.

You are right Eric. If it was a W30 it also couldn't have power brakes and that's a power brake booster I see there. I'd like to see a pic of that cowl tag and VIN.

OK, here's my take on this. There were NO Supreme hardtop 442s. HOWEVER, the 1972 Hurst/Olds WAS based on the Supreme Hardtop (4257 body) AND a very few were built with the W-30 motors and an "X" in the fifth position of the VIN. These cars would have had power disk brakes, buckets, and console with dual gate shifter, none of which are present on this car. I am curious about the very low build sequence, however. I've asked for photos of the VIN and cowl tags, which are suspiciously absent from the photos in the ad. This car is obviously not a Hurst/Olds. We'll see...

Allan R

I'll wait to see your results. Not much point in me asking the same thing to the guy. Is it POSSIBLE, ( I know highly unlikely) that this car was special ordered with the L77?) It also doesn't appear to have the dual exhaust/cutout bumper that should come with the X code motor.

1970supremevert

is this car located in canada?? I noticed the lower case c in front of the price?? and I see it has Ohio plates, I have never seen that lower case c on any auction??

w-30dreamin

I think the X is a typo on the sellers part,probably meant to type in a K for the L34 - 350 4V.

I think it's just a Supreme with a transplanted big block.

If it were a w-30 engine,why would they remove the aluminum intake?

Is that a 1970 style muffler on the AC compressor.

No 4 row radiator.

Allan R

I think the reason it shows a C in front is because my ebay browser is ebay.ca instead of ebay.com You mean Canada with a Capital C right? My browser says it's currently at $US 3,050.00 which is $C 2,990.22 and has 21 bids so far. The seller is registered as a US member, so it's likely for sale in Ohio.

marxjunk

probably a title typo seen it a 100 times...instead of looking at the VIN they just copy whats on the title and if its wrong..it can get ugly...

joe_padavano

DOH! Of course that's what happened.

stevengerard

W30s with automatics can have AC and/or power brakes from 70 - 72. I'm guessing its a K in the VIN as well.

Windshield washer jug on driver side also usually indicates 350

jensenracing77

i believe that changed in 72. i don't have a document but feel real sure that A/C was not available with the 72 W-30. the power brakes were available.

Dave Siltman

I have a '72 442 with a factory 455 and washer jug is on driver side. My car also has original coolant overflow bottle that Is on passenger side. It also has factory A/C.

507OLDS

It's a K. Just a regular CS like my 72. I've only seen one 72 HO X-code pop up for sale in the last few years,and it was in the New England area,and begging for love.

RetroRanger

I think I remember that car was it ayear or two ago well rusted and in SoNH area maybe swanzy or troy listed on NH CL ?

allyolds68

I originally posted the link to the CL ad on ROP. The car is owned by a somewhat eccentric body guy that knows what it's worth. I never looked at it but I think stickw31 did. mcalvo on ROP had bought a 68 442 from the same guy a few years before. Very rare car

There were only two (2) 1972 Supreme s built with the W-30 option and they were sent to Hurst (Dimmer Engineering) for conversion in to an HO. Also, they were both "sun roof" cars. Don't know anything else about them. I saw one being restored in Green Bay, Wisc. for a person I know who owns it, that lives in Austin, TX., back in 2001!

GAOldsman

Yup it's definitely a K. Edit: Now I'm not sure if it is a K. Looking at the enlarged photo of the engine like Allan says looks too wide to be a 350 and plus you can see the blue valve covers. But definitely not a L-77.


No ram air hood nor does it have the cutout bumper with dual exhaust. As for a Cutlass Supreme Hardtop Coupe with the L-77 it did happen and as noted earlier on the H/O (W-46) but I believe there were a very very few that weren't H/O's that did make it out of the plant as such. I can't find the production number of the 3J57X2M right off but it is out there and I don't mean just the W46 either.

oldsmobiledave

Come on guys...all this speculation over a nothing car. Clearly this is a base 1972 Cutlass Supreme....nothing special. There is no way this is an X code car. The VIN should clearly have a K in it & has been mistyped or misread by the seller.

If the seller would post a pic of the VIN all this discussion will end.

As to the 3J57X2M cars I have the full VIN for atleast one of them....It is an HO & I am pretty sure it is one of the Sunroof equiped HOs referred to above.

I might have a second one in my notes too....I will check my list of X code VINs when I get home from the Oil Rig I am on. I have a vague recollection of two 3J57X2M cars on the list I have kept of all the X codes I have encountered.

Allan R

So, what did you get back?

69'442

I asked him if he was sure it was an X. He replied and said it is a K but looks almost like an X.

oldsmobiledave

Well there you have it...it is ALMOST an interesting car.

joe_padavano

I was off-line at Carlisle all weekend, but yes he did. His response was that he couldn't get a clear photo of the VIN...
