I'm in the process of collecting the correct missing engine parts for my 71 TA.My goal is to have it running by the spring.Allthough none of the parts have been cheap, at this time the orginal carb is not in the budget.This is a 4 speed car and their is a service replacement carb on ebay for a 70 4 speed TA. Any thoughts? Other options? Thanks Todd

[Lloyd-TX]

Since you're not going to pony up for a correct carburetor at this time (and I don't blame you!), give Cliff Ruggles a shout and see what he's got to sell.

Good luck!

In MY mind,ANY 1971 Pontiac Q-jet would be better than a 1970,as there are lots of minor differences in between those years.

You can't read the #'s with the aircleaner installed,so "correct looking" is WAY BETTER than wrong year.

[68bird400HO]

A good replacement is a 7041263 carb which is the 1971 400 4-speed carb. They aren't real easy to find either but they a lot cheaper than the 7041267s.

[Transamric]

My opinion is the same as the others. For the near future, any Pontiac 7041xxx Qjet would be preferable to any 7040xxx.

Todd, I have a 7041262 that has been completely restored. replated, etc. I bought it thinking if I couldn't have what I wanted, I could at least have a nice looking, functioning carb on my car that worked well. I was like you needing the correct carb for my car. I needed a 7041268 for my auto bird. Finally scored one on ebay while everybody with way more money than me was asleep. the 7041262 was for the other FB / All 1971 455 auto cars. I would let you have it for what I got in it. It's still new in the box unused. This may not be compatible with the throttle set up on a manual shift car...I don't know. Just trying to help.

[T/A Fanatic]

I run a 7041263 on my '71 455 H.O. and it runs just fine! It's set up to handle up to about 450 hp and works well with my combination. It will do until the day I win the lottery and can afford a 267 (assuming I ever see another one for sale at a price less than stratospheric).

I have a 7041267 with a date of 2080 so whats it worth?.

[1971455HO]

Your 7041267 (dated 2080) is worth quite a bit for somebody needing a July 27, 1970 build date for their '71 455HO Goat,TA or Formula 4-speed car. Depending on how correct it is, somewhere between $500 and $2500. $3500.00 NOS in the box. OR MORE ??? Whatever the market will bear. I was lucky enough to get my rebuilt, but not show quality, 268 for a little over $600. They had been going for $1500 - $1800. I couldn't compete. Guess I caught everybody broke when I got mine.

[spb350]

HMMMMMM might be time for an Ebay auction. The carb should be completely original, never rebuilt. The guy I got this from bought it, and a HO intake in 1973 or 1974 to put on his Formula 455. In 1975 he bought a SD motor and parts and pulled the original 455. The carb has been sitting since 1975. Probably less than 10K mi. If anybody is interested and has questions about any other numbers on the carb let me know. I'll post here if I decide to Ebay it.

2many- could you please explain to me(or anyone reading) why ANY 71 Pontiac Quadrajet would be preferable to a 7040xxx style carb?? minus the 2 TA HO numbers and the 2 '71 GTO HO numbered Quadrajets, ALL of the other 1971 Pontiac 4 bbl Q-jets areidentical to the 1970 models. Actually most of teh 1970 models are better. they more tunable since they don't have the primary pull over system as the bulk of the 71 models do. ANy of the high compression Q Jets are way more tunable and better in my than the 71 up ones. ANd truth betold, the 800 CFM vs the 750cfm (really 780) 1970 models is negligable. ANd the single venturi is way more fickle than the triple venturi of he non HO models.
BUT, i got off my original question. help me understand why you think 71 model Q jets are better than 70 models<> I am confused on this one..

[2manyT/A'S]

Hi Bill

NICE to see you back with us AGAIN!

How was rehab? (hope you got it "sorted out" this time)

I guess my post regarding 70 vs 71 q-jets could be a bit misleading (if you are reading from the bottom of the thread?)

Personally,I've found that 70 & 71 Pontiac quadrajets have quite a few differences.(cosmetic,anyways)

Most noticeable would be the float bowl vent in the air horn.

You might want to check that out?

My comment suggesting using the "correct year" Pontiac q-jet was made from a cosmetic & NOT a performance standpoint.

MOST q-jets of this era can be set up/tweaked to produce the same performance levels & using the correct year/style to match intake manifold,fittings, linkage,etc. just makes sense to me,UNLESS you are building a modified car or don't really care about the "details".

These days,the majority of people seem to want a stock appearing engine & a correct for the year carb & intake (to match year of car) just makes for a better looking engine detail.

Hope this helps??

[71HO4SPD]

Has anyone ever seen #7041273 on an original numbers matching '71 4-speed Trans Am?

2Many- you are such a prick. your comment about rehab is not funny at all. I don't do drugs nor do I drink not a drop of beer,whisky,wine etc.. just not for me. and making fun a rehab is completely off base. it is not a funny subject.there are people who honestly have problems with drugs/alcholol and it ruins their lives. so making fun of that is just wrong...I guesss you would make fun of the guy in a wheel chair also... yes, you are a mental genuis....your command of the english language is quite impressive...

[klunde]

DUDE,,,,,, Chill.... Me thinks he was just being funny.
Why can't people laugh anymore? Life's way, way to short.
Now should I sit back and wait for hate mail?

Hey Brian, how are you by the way?
Lots of snow up there?
Kurt

[TA455HO]

Kurt, how is Bellingham? We got about a foot of snow here in Bellevue. I'll bet Vancouver B.C. got hit about the same or more.

[2manyT/A'S]

It's ONLY the SIXTH day of winter & I'M done,ALREADY!

Supposed to warm up & rain tomorrow?
(I've got my fingers crossed)

[klunde]

Bellinghams great, just white as can be.
I've spent at least 4 hours a day for a week now towing my girls on tubes on the quad.
Four tanks of gas so far. Plus two snowmen. and one dig-out with the tractor.

What are the chances, I could stop by this summer for a ride in a bird?
It could get my blood pumping to pull mine out and start the resto....

Or I could cross the border and steal one of Brians., maybe a green formy.

What went down on that clean 70 (or was it a 71) you were looking at last summer??

[unruhjonny]

Im a little late to the party, but please allow me to try to help;

the following carbs are 800cfm castings;
7041263 = 71 L78 mt
7041267 = 71 455HO mt non-RA
7041268 = 71 455HO auto non-RA
7041270 = 71 455HO auto RA
7041273 = 71 455HO mt RA

According to most sources, the TA was supposedly built as a non-RA car, and as such most received the 267 & 268 carbs; but there are exceptions to the norm.

if I were you, I would first look for an 800cfm carb, but if you can not find a reasonably price example, I would aqquire a 1971 carb becasue you can simply cap the automatic specific vacuum feed, and sticking to a 1971 casting allows you to use the correct throttle arm bracket, while having the correct top plate and mechanical choke hook-up.

The easiest to find example will likely be a 7041262.

I would stay away from restamps, because once the carb has been messed with, you cannot be sure what has been modified, or if the modifications are all matched properly.

One upside to sticking with a 750cfm casted carb is that you will get better vacuum signal.
