Rebuildable core okay, but must be in good condition.

I'm not in a hurry to get it. I don't want to consider any other numbers.
Can email me at kurt.shubert@wildaboutcars.com

Thanks,

Kurt,just curious in 68, have heard some manual cars came w/ 251s and 253s in later production Is this accurate, because honestly have never seen a 68 253, thanks Dean

wmachine

Thanks for bringing that up, Dean. I've not heard that, but I'll look into now. A quick check tells me that may be a possibility. '68 was the first year the stick 442s got a different carb. 253s got larger primary jets than the 251s, and that may be the only difference.
I have evidence that early W30s got the 251 carb, so it is entirely possible that the 253 carb lagged behind too. I'm noting that the W30 (254) and W31 (255) carbs follow the numerical sequence.
This will be interesting to check out.

The 253 jets could be added to the 251 carbs and that would give one functionally a 253.

I'm not a 68 carb expert by any means but I've read a lot about the subject. There was a great thread on the 68 253 carbs on ROP before it crashed the last time. Chris Witt's quote went something like "never been photographed in captivity". There were definitely factory replacement carbs with that number but the production dates were in the early 70's.

edit....Found the quote here on ClassicOlds:

dnmfranco

same here far as expert, but never ever seen a 8 - 253.
Kurt if you do find one in which I hope you do please post a pic Dean

wmachine

Thanks, guys. I'll certainly pursue this and see what I can find.
As far as my own use goes, I'll be happy with a rejetted 251.

That's funny that this text is still findable.
I repeat, rumored to exist- the "calibration carb" in Texas for example, but, much like the SMW 403 of lore, evidently not one photo exists. We have better images of extraterrestrials and Bigfoot.

wmachine

So Chris, are you refuting the replacement carbs too? You didn't exclude them. So if you haven't seen them they don't exist, huh? Mike says they do.
No, this is not at all like the SMW 403. There are numerous factory document references here. That is far from a rumor. Doesn't make them exist, but certain more credibility for their existence.

allyolds68

I take that back Kurt. I just went back and looked at the thread that had that info and it was a 7049253

I'm a dumbass! I hate it when rumours get started like this

wmachine

Thanks for the clarification, Mike. I'm not trying to get anyone is trouble here, you or Chris. Just trying to get to the facts.

dnmfranco

Kurt, just remembered a few years back I was looking for a 253 as well. I found this company (don't remember how) called Carb Junkys they are out Atlanta Georgia. Now when I called them they said they had 253 cores, they would rebuild it for 499 I believe. Now whether they re-stamp or not that I don't know however to test their knowledge I asked well do you a 68 255 and they laughed due to its rarity so I think they are legit. Its worth calling them - 866-961-2272 they have a website as well -www.carjunky.com. Let me know I would be curious. Dean

think i got one in Al's junk.? will look over weekend. it was with the 68 442 G block motor he was going to use.

Octania

I have never said the '8253's "do not exist"
I will say however that I have never seen one, nor a photo of one.

Whereas, I have one of 43 '68 W30 AT convertibles.
I have a 4A 403 engine
I have a prototype intake
I have had a Corvette ZR-1 engine
all w/o even looking, really.

I have TWO '8254 carbs, and some '9253, and a '9254. None of which are common.

Yet, years and years of searching for the '8253 carb has produced only rumors, not one photo.

Today's google search finds... this thread.... some photos including an "actual photo":
http://www.carburetion.com/CarbNumbe...Number=7028253
It says it's an actual photo, so it must be! Not sure OF WHAT, but it's actual.
Oh, wait, "This carburetor has a part number of 7028253 and used on 68-69 olds 350-400 exc toronado"
So, other than the bullshed about what its APPLICATION number means, and the lack of a date code, and the utter failure to show the actual stamp... that's proof positive right there.

AHA
expired ePay ad, no longer has photos
http://www.ebay.com/itm/290688292425...84.m1555.l2649
bears ;ate '67 date code per ad text.

I would be interested to hear more about this "replacement carb" - is that like the ubiquitous '9254 NOS carbs dated around 1975, which everybody seems to have one of? Still falls under "never seen so much as a photo of one."

Chesrown, do the world a favor and generate and post a few clear well lit in-focus photos showing the features of this rare beast.
Application stamp
Date code
1968 specific throttle peg
casting ID [circle things]

Then we can cross that one off the Bullshed List.

"So if you haven't seen them they don't exist, huh? "
====================================
Well... yeah, pretty much.
I have seen just about everything Olds related.
I gave up claiming to know all after the L shaped notch was found on a [small block] cast iron crank.... and of course onesie twosie oddball things exist.... like Rocket Science's "SMW 403" with a std ordinary 350 casting ID 395558-2, but anything Olds that was made by the hundreds or thousands.... yeah a Lansing boy would have see one of those by now.

Octania -- My comment was an "inside joke" between Kurt and me --- Tongue was firmly planted in cheek with that comment --
Sorry if i got anybodys hopes up!! LOL!! I guess i wish you "happy Hunting" in your quest of search for this "holy grail" eluisve carb #!!

Kevin W

Kurt,

Did you ever find that 253 carb?

On the 254 carb, do you have any idea at what point in production they were available and installed?

dnmfranco

Kevin I heard early 68 W-30s came w/ 251's - later builds 254 . But have no idea as to when that occurred but can ask Dave if Kurt doesn't know

wmachine

No. A couple leads that didn't pan out, and a couple more pending, but nothing that has put one in my hands yet.

Don't know when the 254 carbs were "available and installed", but should have been for the W30s that I believe started sometime in November.

wmachine

Very well may have been that way. Would be a very difficult thing to document. Considering the nebulous existence of the 253, it is apparent that some irregularities were going on with '68 carbs.

Kevin W

The only differences between the 68 251, 253 and 254 carbs are the jets and rods, correct?

It's amazing that they would have such a problem with the numbers, it's not like the number is part of the casting, its a stamp. Not unless they had assembled a ton of 251's and they didn't want to wait for blank castings. Doesn't make much sense.

This is the # for an oldschool carb mechanic . His name is jerry hallman , located in Birmingham Al . 205-222-1669 . Its worth a try if you cant find it , or he might be able to head you in the right direction ? You can google him , thetes a fair amount on the net about him .

GM parts guy

I called the guy in AL,and the guy at the quad shop in Rockford IL back in Aug.They both told me they cant find a 253 carb anywhere.They have never even seen one before.They said they have the 251 carbs?I talked to a guy last week about some Olds stick carbs from the 60s-70s.He said he may have some 1968 442 carbs?We will see if he has any 253s or not.I have a original,so I know what to look for on these rare carbs.I will post what i find out about these carbs.You just never know whats been sitting for years in some guys shop.

wmachine

I'll exclude the 254 (W30) and 255 (w31) from the following details as there were other differences with those carbs and much more limited applications.

The difference between the 251 and the 253 is just the jets, same rods. They may have different throttle bodies too, as I think Bill Demmer determined. The 252 (Toro) carb apparently shares the same internals as the 251, so I'm guessing the 252 has some external differences.
But what that all means is that yes, it is puzzling that they did have so much trouble with the 252,254, and 255 carbs in 1968

On thing to keep in mind, though was that in the preceding years, there were much fewer different carbs. So the stumbling in '68 probably had something to do with that.

WTony

Just for the heck of it someone should call to see what carb # is on this rusty hulk.

dnmfranco

is that car still available ?
called the guy when it was first listed he said he was too drunk to talk and to call back lol

allyolds68

I saw that listing too. That POS must have been six feet under in Sandy

Still looking?

GM parts guy

I checked out the carbs in WI.No 8253 carbs.Everything else but 8253.I will find another.

wmachine

I have some leads, but nothing in hand yet. That carb was apparently misidentified. It is a 252, but thanks.

allyolds68

Mike,


If you read through the whole thread it ended up being a 7029253

66-3X2 442

OK,I didn't read the entire thread,I just did a search for the 7028253 carb because I remembered seeing the picture of the carb.

I can tell you this,the Hollander Interchange book recognizes the 7028253 carb. I don't think they would unless it was a valid #. I guess until somebody comes up with one,we'll just have to wait.

66-3X2 442

I know Jerry Hallman very well. We have been friends for over 45 years and the reason he probably doesn't have one is,his storage building burned to the ground with literally hundreds of carbs in it. That was a sad day,he lost all of his carbs he had been saving.

GM parts guy

I have the one and ONLY original 1968 442 7028253 carb in the US!I have been told less than 100 made.NO one can find one anywhere?I have had this carb for over 10 years.Now might be the time to sell it.This is the most rare and hard to find carb olds ever made for 68.Its not the money,its the numbers.Numbers= money.I will list it on ebay soon.This is not for the weak of heart.ITS NOT CHEAP.It will only be for sale once,then put away for another 10 years.This will only go up in$$$$$.

allykatt 1992

When did this happen ! Was it that building in birmingham or at his house ? Thats to bad . He is trully a good person ! A honest person !

nsnarsk65cutlass

Really the one and Only?That sounds to me like retirement $$$$$

66-3X2 442

It happened maybe two years ago. His storage was @ his daughters farm in a building that burned. I know he was very sick about it. Yes,he's a great guy.

GM parts guy

I dont know about retirement.But I do know its the only one!I have called all over the US for one of these rare carbs only to be told[YOU WILL NEVER FIND ONE].So thats why I say the ONE and ONLY 7028253 carb.You can call around and see for yourself?Please do so.You then will see what everybodys been talking about.

GM parts guy

Its to bad about jerry hallmans carbs.But he didnt have a 7028253 carb that went up in smoke.He may have had some rare carbs that were lost, but NO 7028253 carbs.

RetroRanger

maybe it will go up in value....but realistically at some point in time there will be fewer and fewer people who know or care about it at which point it will be just another qjet and worth less and less untill its value bottoms out at core value. As the older more dedicated olds fans move on to greener pastures fewer and fewer younger fans will take their places and as the numbers dwindle so will the apparent value of rare cars and parts... if nobody cares about them nobody will want them ....

so if it doesnt sell dont put it away for 10 years because you may find its already worthless !

tell ya what Ill take it off your hands so you wont be stuck w it

GM parts guy

I think the 1968 442 sticks cars will be around forever.I think someone would love to have something nobody has?Its our human DNA to want what we cant have.And when we find it,price is not an option?Its all about the have and the have not.I think it will only go up in $$$.I have no problem with putting this 253 away for another 10 years.
