I was wondering if someone could tell me their opinion of the value difference between 1969 & 1970 RA Carbs - specifically the 270 carbs.

I have observed that (with the exception of the very early "1968" units) the 1969 7029270 carbs are a good deal cheaper on average than their 1970 7040270 counterparts.

Is this because there were more RAIII/IV cars built over the 1969 model year making the OEM and SR units manufactured in higher quantities than 1970 model year units?
And/or it somehow tied to the lengthened 1969 Firebird model year?

I am asking that because I have a SR 7029270 carb atop my '70 YZ engine - and to date, this is by far the closest I have ever been to having this engine complete and correct - but I'd kind of like to get a '70 carb for it...
think of it as icing on the cake...

I would also appreciate opinions of the value difference between SR & OEM units - as I have once again observed (for logical to me reasons) that the OEM carbs carry a much higher price tag than the SR units.

BTW, I am posting this here, because I have noticed of late that when I post something f this nature in the lobby, I get alot more scoffing than actual help.

I think you will find it is because of the 70 TAs, the 270 SR is also the SR for the crazy expensive 273. Like the parts for the 70 TA (IE JWs) I think it has driven the 270 carbs up in price. I have a 270 that I have been on and off going to sell to a guy (dated not SR) but he has not moved at all on it in a while.

I have seen quite a few 7029270 carbs over the years with later dates, making them replacements. I couldn't tell you how much they go for, but I know I sold the ones I had fairly cheap. It's been at least ten years since I had a SR 7029270 carb, so price data may be moot. I think I probably got 25% of what I would have gotten if it had been an original dated carb.

I think a 7040270 carb will set you back at least $2500 if you find a nice unmolested one, particularly one with dates that match up with a Trans Am or Formula. In general, prices have stayed high on these carbs, they are down from their peak but are still expensive.

270s don't bring that kind of money, typically 1500/2k in my experience. The Sr version seem to be 5/800.

see, this is where my own personal "disconnect" comes in;
I was wondering if maybe because I haven't closely followed what has sold versus listings being unsold then relisted at the original price, if this was skewing my perception of things.

I have been seeing values something like this (I'm typing this using my gut feelings for values):

early '69 OEM 7028270: $3,500
'69 OEM 7029270: $2,000
'69 SR 7029270: $900
'70 OEM 7040270: $2,500
'70 SR 7040270: $??

My gut tells me that the SR units fetch a fair amount more than the proposed 25% of an OEM unit;
I seem to recall seeing many list higher than this, and obviously both years of SR '270 values are bumped up because they are a legitimate replacement for the '273 carbs (I observed that somewhere around 1972 the 273's stopped being made as SR carbs).

I specifically didn't ask about the '8273/'9273/'0273 carbs because it appears as though they get ALOT more money, and for that I am glad my car isn't an original RA car, because it seems like prices get a little nutty here (again, these are purely gut feeling prices here):

early '69 OEM 7028273: $4,500
'69 OEM 7029273: $3,000
'69 SR 7029273: $3,000 (very rare; shortly superseded with the '270)
'70 OEM 7040273: $4,500
'70 SR 7040273: $3,500 (very rare; shortly superseded with the '270)

But getting back to the original intent of this thread, I seem to see the SR 7040270 carb in much lower frequency than the SR 7029270 and that had me wondering the difference in value between the 1969 & 1970 unit...

I think they are closer to 1000 to 1500 if you don't want to wait a few years to find someone who is desperate for it.. Over 2k for a 270 is crazy. Just because one may have sold for that much in 05 does not make it the market price.

I have had a couple of Sr 7040270 s and they just don't bring all that much 500/1k seems to be the number

I agree but I paid around 1500/1600 for the 2 I bought lately. One was done and ready to bolt on

thanks guys, I very much appreciate your input - I am guessing that ePay is skewing my perception...

[RAIVJUMB]

Those were dated 270s the Sr I think I paid 600 for

In my opinion not much difference in the value of a 69 or 70 original non SR 270 RA Carb. 273 are maybe worth a little more. I paid about $1000.00 nearly 15 years ago. I think it is the date code and condition for some one that drives the price.

By the way, I have very nice 7040270 dated 1250 that is close to date matched for my 70 TA, but is Early May. I am looking for a March or April dated one. Consider trade or cash/trade for similar condition.

Not to get of topic but I have never heard of or seen a SR 273 I'm sure and was told by Cliff R that all SR RA carbs where the 270 because they fit both applications.( Auto or Manual).
Just plug the auto port for using on manual cars.
I think if you come across a later dated 273 it might be a clone? Am I wrong?

[RAIVJUMB]

I believe that to be the case as well

no, it appears as though the '273 carbs were made as SR, but only for a VERY short period of time - I don't recall seeing any made after 1972.

7029273; 54th day, 1972


7040273; 223rd day, 1972


they are out there, but my guess is that they are actually rarer than OEM units - pretty quickly MPC's started calling for the same year '270 Quadrajet as the SR unit.
