I've had this NOS SD service replacement carb for many years & once I've figured out what it's value is I'll list it for sale.

I know SR carbs don't have the value of production carbs but the "new never used" factor has to bring the value up I would think. I haven't seen one sell in a long time & I wondered if anyone here had an idea on what to expect out of it?

It's a 17054910 stamping with a date of 2847. Thanks!

I'll open the bidding at $500.

I knew I could count on you Chris!

I sold a brand new SR carb for a SD for $1400 on eBay 5 years ago.

I have seen them fetch near OEM $$;
But aside from 910 & 911, I don't know the SR part numbers...

Sorry for the tangent, but does anyone have numbers for other SR carbs?

[blue71ta]

I would say it's worth about the same as a production-dated 7044270 that's in used condition

I could see this.

I wonder if these are a result of Rochester changing their tooling to the revised float bowl depth (this is how I've understood it);

70 = 1st design float bowl depth
170 = 2nd design float bowl depth

They both require the use of specific length primary needles.

I have observed the following series and decade codes:
702 = 1967-1969
704 = 1970-1975
1705 = 1975-1979
1708 = 1980+

I wonder if that carb's date code was actually for a 1987 manufactured carb, as opposed to a 1977 date code (as the first three numbers are the sequential day of the year, and the last number is the last number in the year's date...

These carbs do jump outside of the domain of my previously understood numbering system (typed above), in that the year code is actually for before the start of the sequencing - but the "5" indicates it's for the 1970's.

?? - it's a puzzle, and I'm a sucker for a puzzle

There were only a single SR part number per car..No manual tranny numbers were ever made in SR system. All SR carbs will have the auto number..I think that carb is worth $1500, just a matter of finding someone who needs it.. You sort of have a problem..it is rare, and being rare is just the problem. Your market is rare as well.

I guess that would make sense why the 7029270/7029273/7040270/7040273 carbs are worth so much - they are applicable to the RAIII & RAIV...

[70RAlll]

yes and no.. good example is there is a guy on ebay that has been trying to sell a '1268 71 HO production carb for a while at $1600, it is worth every penny of that. but being rare, his market is equally as rare. unless there is the owner of one of these rare numbered carbs vehicles looking for a particular carb..well, then it is just a 40 years old Quadrajet..And SD's seem to have been the least messed with 2nd gens out there. the intact survival rate must be a large multiple of RAIV,RAlll and/or HO's.. SO I bet there are very few SD guys needing a numbered carb. And if there are none currently, well that is just a 40 year old Quadrajet..

[RAJ7395]

Bill - I couldn't agree more. I've had a 7028270 carb that I've been trying to sell for years. Rare carb but can't find a buyer for it.

iirc thats going to be 1968 RAII/auto right?
7028276 = '68 RAI/auto
7028277 = '68 RAI/manual

...I think that's an awesome carb.!..I would not put it down because its SR..(I have a 1975 SR on mine, replaced for whatever reason)if I needed a carb.,I would want that over a used one no matter what...easily $1500 (or more)...but I have a question...I see on E BAY CARB PAL sells 455 H.O. carbs (I do not need one) for $450 with a $150 core charge at that price...THE PARTS PLACE sells them at $549...where they get them, who knows..I see numbers like 7042270/72 AUTO and 7042273/76 for manual...in the pictures they certainly look correct..are these the real deal for H.O. cars?...they just seem inexpensive and easy enough to get...I realize S.D. & RAIV are totally different but for owners of 71&72 H.O. cars,..is getting a replacement carb. not a big deal?...and these carbs are all redone and ready to go...of course who knows how they are set up but CARB PAL on E BAY must have a somewhat business doing this...thoughts?thanks

Those are the numbers for Firebirds and the 7028276 is the most common 68 RA carb number to see - I believe it was the only one offered for SR.

The GTO numbers listed in each of the books are 7028274 Auto, 275 Stick for RA I & 270 Auto, 273 Stick for RA II. I could be wrong but I honestly haven't seen one of the 274 carbs and being that more than 158 of them should have been made I find that odd. Being that only 47 of the 270 carbs were made & I've owned 5 or 6 of them at different times, along with the early date on the one above - I'd have to say the 274's and likely the 275's were never used.

Sorry for the tangent, back to the SD SR.

I think the original intent of this thread has come to a close, so I'm fine with the tangent...

That is because they are all restamped Franken-carbs and in no way original. A real 455HO or SD carb costs a whole lot more than $450.

[1971455HO]

Amen!

Well since the thread owner doesn't mind, here are pics of the one I've got. If you see anything wrong with it please point it out. I'm not a carb expert by any means. I bought this one for my 69 TA from Cliff years ago and it has just wrapped up on the shelf. At the time we all thought that the left over 7028270s were exhausted well into the 69 model year but didn't know when they ran out. I've since learned that the 7029270 was in production at the time my car was produced so this one is incorrect for my application.
