no, they couldn't meet emissions with the t-quad....

IMO, the Q-Jet is a much more reliable carb than a Thermoquad. Unfortunately, Thermoquads don't age well and can be incredibly tempermental -
Sorry, that's nonsense, they "age" just as well as any other carb, nothing works right if it's been broken, poorly rebuilt or modified, or has been "tuned" by someone lacking the proper knowledge to do so properly. Once adjusted properly they require VERY little adjusting, no more than any other carb design, not tempermental at all.

especially the later ones equipped on Lean Burn/Electronic Spark Control engines.
While certainly not the best as a performance carb in stock form, they worked fine in stock applications if all else (non carb related) was in order, however, most the time that wasn't the case.

While Quadrajet carburetors are mainly known for their use on GM products, they did use them on some Fords, Mopars and even many marine applications.

And as far as you using the word thermobog ? EFFEN you use the proper tool to adjust the secondary air-valve .... this potential-issue would not be a problemO.

This is not what I heard Patrick .....
Back in the 80's I had not even handled a TQ .... OK - I admit ...I was a Berry-Bumz back then ... BUT I saw the light and corrected my errors !!
But I heard that the reason the OEM dropped the TQ is because Carter dropped the TQ ....because they saw the handwriting-on-the-wall ...that carbs were going to be DINOsaurs in no time.

I don't buy that. If carter had chrysler, a large OEM customer they would not just say 'too bad' to chrysler, shut down the thermoquad factory and destroy all the tooling for it. The notion of the thermoquad factory burning down seems a lot more plausable to me.

Not asking you to "buy" anything .. that is just what I remember happening. There was never really any good "aftermarket" demand for the TQ(vs the Berry) ... and there WAS that "handwriting" ... and Chryler's OEM demand for the TQ ? .... vs say their demand for a the TBI's that they were putting on most of their vehicles at the time .... was an ant-hill vs Mt Everest. WHEN WAS the last carb installed on a Mopar ? ... and how about the other companies such as GM and Ford. I don't know ...I am asking. But it was not THAT far off from when Carter dropped the TQ.

Federal emissions requirements killed the carburetor, the OEM's saw that FI was the way to go to be able to better control the A/F mixture under various conditions.

I'm not arguing the fact the handwriting was on the wall for the downfall of the carb. But carter had way over a decade of build time on the thermoquad, I don't think they would have just decided to throw out all the tooling, infrastructure and training they had invested into thermoquad production while OEM orders from chrysler were still comming in. If chrysler changed carb suppliers for whatever reason, maybe the TQ couldn't meet emissions standards??, that would make more sense. If the OEM orders ceased, and with little aftermarket demand for the TQ, stopping production and changing the factory to produce some thing else would have made perfect business sense. IIRC, mopar started putting quadrajets on the v8's several years before the tbi system appeared on a mopar v8.

From what I remember hearing ... the TQ was a muchO BESTer emission piece than the QJ ...again it was all about that "handwriting". And I say that Carter saw-the-light sooner. SURE Chrysler would have kept ordering ... but at what kind of volumn ...vs what they were with the TBI systems?
For sure .. ANY carb can not hold a candle to a good TBI or DPFI system in most every way. Their decade-of-R&D on the TQ ...was good while it lasted.
And for me ... I did not appreciate the FINESE that the TQ had(over all the others) ...uNtil way later.
