So I bought a rochester carb on fleabay tonight. Correct numbers matching for my 1970 w-30 with a manual trans. I paid 510.00 for it. It realistically comes down to how bad u want it and how much ur willing to pay to compensate that want.....well...I wanted it... BAD. LOL. How many do you ever see right??? Now the only thing I am missing to complete the motor is the distributor. Never the less, the other side of me is wondering if 510.00 was a good number for it, or did I go alittle to crazy. Its in phenominal condition. Whats everyone think???

 

Let's see a picture of the model number on the side...

I'm not a W-30 collector, but $500 is a lot of bananas for a QuadraJet.

- Eric

 

The pic is from the auction. I crossed it to the listing on the olds faq carbs section and is correct. 7040256

 

I'm not a carb authority, and there are others on here who are, but, personally, I don't like the looks of it.



- Eric

 

I'm not an expert either, but a concern is that someone may have ground off the original number which was common and re-stamped the rare number. There was a batch of carbs that looked new and were rare numbers recently hit ebay. Attached is the thread:

Hopefully yours is the real deal, if not then consider it like a reproduction part. Something that you couldn't locate the correct one so you acquired one that's been made to look like the original. The one sticking point is if you sell your car please be clear about the history of the carb on it.

FWIW - 2929 = Sunday, October 19, 1969

Sundays are an uncommon day to have a UAW part built.

 

& isn't $510 about 1/2 what an authentic 1970 W30 manual trans carb is "worth"?

 

same seller

http://www.ebay.com/itm/1970-Olds-44...p2047675.l2557

 

Yup, same seller selling suspicious restamped carbs with no history, for big bucks.

Thanks for finding those threads, John and Hurst.-

TicTocTach, have you shelled out any money yet?

- Eric

 

A restamped rebuilt runs $549.00 + $100 core charge from a Olds vender.

 

So... He got a bargain on a misrepresented counterfeit part?

- Eric

 

I agree with Eric, if you haven't paid for it yet this would be a good time to verify what it really is. John

 

It only went to $510.00 because it is not legit.A real one will bring over $1,000.00,and the guys looking know what they are looking at.That date is not one of the dates that they were made. Those carbs were made in batches at a time,in one day,then another batch on another day,etc.
The airhorn is also not the correct one for the 256 carb.

 

Tell me what to look for when this thing shows up as yes, I already paid for it. This way I can with out a doubt verify its def not the real deal so when I call paypal and send this thing back, I know what I'm talking about. Unfortunately when I saw the auction last night, there was about 15mins left and I was on my way out the door. No time to do any research on it. So I rolled the dice and bid not really knowing anything other then the fact that the serial number matched. Never even considered a possibly reproduction carb. That's what happens when you roll the dice. We have all been there at some point I'm sure. But please let me know what to look for here. Pictures, specifics, anything at all cuse as it seems so far, it's going back.

 

i agree the stamping numbers look 'soft'...and since when did the united auto workers have a work on sunday in their contract

 

I would send a PM to 507olds with that question.

Some if the details are very particular, and some are better not broadcast.

- Eric

 

ebay will refund your money if they feel it was misrepresented...but your probably not going to convince them of that by steting it was restampted but as brian trick states if the airhorn is different and you get a picture of an original to compare you might get your money back...the key here is did the ebayer post this as an original

 

No, he doesn't state it to be original. He words its perfectly as saying "correct". Which is true for a reproduction carb, right? Lol. Uhhhh annoying to all hell. Here's what's stated in the auction ..


Welcome to my auction for a Quadrajet carburetor correct for a 1970 Oldsmobile 442 w30 optioned Engine. Numbers on it are 7040256 UA 2929 This is for 1970 w30 Cars with Manual Transmission. It has not been run.
Carburetor was purchased at wholesale price and is being sold as-is without warranty.
It does appear to have been recently rebuilt as it looks practically new but please assume it will need a kit just in case. NO RESERVE 3 DAY AUCTION~ Starts at $100
I picked a few of these in the same condition so please look at my other auctions, please ask questions before bidding.
Please check out my other auctions for hard to find carburetors

 

Additionally, the UA "production code" is not what I have as correct.

But I have to say, what is the blind obsession with a correct *part number*? With no apparent concern for what the part is and what's inside??????
The original reason for the part number was so you know it is the "correct" part. Now we are just concerned that the numbers only are correct? Even if the guts aren't?
That's like paying big bucks for an X in the VIN of a '72 and not even opening the hood to see what engine is there????

This is *one* (and maybe the only one) case where restamps originally were not for deception. You rebuilt a carb with cetain internals for a particular application, then stamped the "correct application part number" on the carb if different from what was there. Remember that was the purpose of the part number? Not to satisfy a narrow minded "numbers matching" market 30 years later.
I don't get it.

 

I understand what you're saying. I am by no means a quadrajet expert in any way. This carb was built 13 years before I was born. Lol. I'm to trusting Is what it is. I go by the correct number and I can hope that the internals are correct. That's why I'm asking for help on here on verifying what would be correct and not once I get this thing. I have no idea what I'm looking at. I took a gamble and if it didn't work out, then that is my own fault. I'm just a guy trying to restore a 70 w-30 with my old man as a father/son project. I came across the carb on short notice on my end and couldn't ask questions and research it more. It is what it is if its not real. But a 510.00 loss I can't take as that money can be used for other parts for the car. I just want to make it as legit as possible and I'm learning as I go along here. If someone has pictures of a real one to compare or just tell me what to look for inside the carb.... It would be much appreciated.

Thanks again guys!

 

there are also numbers on the bottom plate of the carb. but it does look, unfortunately, that this is a re-stamp. And as others have noted wrong date stamp, UA is for a 258 not sure about a 256. I would start out by doing your best to get your money back. But don't kill yourself over it. As others have said a rebuilt re-plated carb would cost between 400-500 anyway.

Chances are you won't find a 7040256 for less than 800 but you never know. If you do find one then you will have to decide if you want to spend the additional money on a carb that will need to be rebuilt anyway or just stick with the re-stamp.

To me a res-tamped carb or a replica manifold doesn't kill the value of a W30 car. Many parts on your car will be reproduction parts. If not then start searching for the real deal, they are out there, just not cheap.

 

the "correct" carb for that stick w30 with m/t only would have no power piston, power piston spring, or primary rods, and used 2g jets. I think you have a case regardless of it not saying original. I would tell the seller to either refund or if he already shipped it try and get a discount based on the correctness and use the carb as a re-stamp and move on.

 

The UA code is correct for a 256. RK is correct for 258,and NA is correct for 255.
Since the carb is rebuilt,and not original/unmolested,you can't determine it,based on what is inside.Yes,the 255 and 256 both came with no power piston,but anything rebuilt in the modern era will likely have added them.With today's crap gas,you need different jetting & such,to get them to run correctly.The 255 and 256 didn't have good idle qualities back in 1970,and would be worse now,on today's gas.
The airhorn on that one was not produced until mid-1970,and used on some of the later 70 & mid-70's carbs.It will work & function,but it did not exist yet,going by when that carb was supposedly made.The more obvious signs that I see,are the swirl marks above the numbers,like a small buzzwheel was used on it.The front butterflies should also have a small hole in each of them.I think they played with that concept to improve idle quality.
The 7040256 carb used the same base,body,and airhorn as the 7040255,up until early-1970,when a few other castings came out,but as far as I have seen,the 255 was the only one that they began mixing different sections & parts,to try & improve idle quality.
A nicely restored carb,like the one pictured,will cost $300.00-$350.00 just for the restoration,so regardless of what carb core you have,you will have about that much in it getting it restored.At $510.00,for it all done,it's not what it is represented as.It was on ebay for the whole world to see,and if there was any inkling of it being correct,it would have gone higher.

 

thanks for the clarification on the the codes Brian, I should have checked my images of correct carbs instead of going by my bad memory

 

I emailed the guy and asked him to not bother sending it as it is def not what it seems to be and here is the response I got.


Jay,

You are getting the carburetor pictured and yes It is not a repro or restamped. It looks better in person
G

 

Perhaps you may get lucky, so good luck.


I am thinking I better head over to my parents garage (which my niece now lives there) and see if the quad is still sitting on the shelf where my dad put many years ago. Although it is for a '71. I know there are a few other items for my W-30 still over there I hope. I do know I had some '67 GTO stuff there but is now gone (BAH).

 

If you used paypal, they will cancel the payment. Not ebay. Check into it. For what it's worth, I hope it's the real deal.

 

Sounds like back-pedaling. Once you get it,it's out of his hands.There's too many wrong things to make it right.

 

would 2479 date be a real W30 carb with 7040258?

 

No. Do you have a picture of it?

 

yes I do, see attached. I also have a 70 W30 distributor as well. Can you verify this is from a 70 W30?

Can post from computer. What is your e-mail address and I can send both

thanks

 

I have a carb guy that I use that's been in my area forever. He's done some of my hollys in the past and is very knowledgeable when it comes to carbs. I have him a shout yesterday. He said he will know if its been restamped as soon as he looks at it because he knows the stamping style used on the original quadrajets. Seems I have no choice but to let the guy send it to me. And that's fine. Lets see what I get. If its nothing like what I'm supposed to get (which seems to be) then I will be calling paypal immediately. And we will go from there. I will give my carb guy a chance to look at it and his determination will be the whether it goes back or not. All I can really do at this point.

 

Wish this was true, as a UAW worker that would like a Sunday off.

 

Fair enough, but did the average plant worker work Sundays in 1970?

- Eric

 

You also have to remember that these carbs were not built at the Lansing plant(Wcars). They were built at the Rochester plant,then shipped.That very same building still stands today,but not the same stuff comes out of it.If anyone ever goes to BTR Performance,you can see the building from his door.
The question would be: Did the workers at the Rochester plant work on Sundays?

 

So I gave the guy the brnrfit of the doubt and had him send the carb. I got it today and brought it right down to my buddy who owns a carb shop locally here. Soon as he looked at it, he said it was a restamp. I opened a case with ebay and 2 hours later got an email saying send the carb back for a full refund. So thats where its going. Oh well!! Thanks for the help guys. If I didnt ask, I would have never have known.

 

Well, you may have gone through some trouble but at least you didn't loose money on the deal. Congrats on that point! Most of us loose a chunk of change when we go through situations like yours.

John

 

Note that the seller has 100% good feedback. You may be offered some sort of a deal in return from leaving good feedback, or allowing the deal to be cancelled with no feedback.
You should think about how you would like to handle that.

- Eric

 

Some guys aren't worried too much about feedback,but I would let him leave it first. You could leave good feedback,and he could still decide to leave you bad feedback,and give some bogus reason for it.

 

What annoys me more then anything is I feel this guy knows for a fact that these carbs are all restamps, and that's fine, JUST LIST THEM ON EBAY AS RESTAMPS! There is absolutely no honesty at all and he hopes whoever buys these carbs gets them and has no clue at all. Looks new, numbers are correct, awesome I have an original 70 w30 manual trans carb! With my situation I straight up said to him via email "if this is a restamp please do not even bother sending it to me, just refund my money and save both of us the trouble". The responce back was "you will be getting the exact carb pictured. It is not a reproduction or a restamp and it looks better in person". So even then I feel he tried to get one over on me by sending it anyways! This is a small olds world we live in. The name is out. Hopefully it'll come back to this guy one day when he sells a 500 plus dollar fake carb to the wrong guy and gets a bitch slap to the mouth. Worth more then negative feedback to me when you consider all the people he's probably already screwed over!
