I can't wait to see my GT-37 that color.

My dad is going out of his mind waiting for this car.... He is calling me 10+ times a day with questions and thoughts. I think he is a bit nervous about getting it, as he has been trying to get one that fit his profile for his "perfect car" for a long time. We have our fingers crossed that there are no major surprises. He decided to pay a bit more and have it shipped inside.

I looked at the picture of the 7041273 carb that is coming with the car and 7041273 is followed by VE then below 3590.... I believe the 3590 is the 359 day of 1970 which would be December 25, 1970, (Christmas day?) unless I'm off on intrepeting that number.

What does the VE stand for? Also, If I'm wrong about the 3590, can sombody set me straight on that!

I also like the blue one and have been folowing it as well.

Thanks Again, Jim

The date is 359th day of 1970, and the plant code is the VE.

I have never seen that date code or plant code before for a 273 for a 1971 RA HO car.

Yours is Lucerne blue too? VERY pretty color. Here is one of mine that color I did years ago.

Just for the sake of argument, I've seen a 273 on a very original 71 TA before - so who knows.

The 7041273 carbs were used for 455HO RA 4-speeds, A-bodes and F-bodies.

Makes sense - good point that the 263 and 267 carbs also had no outer rings, I had forgoten that.

Good links Mike, Thanks.

As Lloyd stated, that is absolutely a non-Ram Air car. I have seen the 1273 carbs on manual trans 1971 T/A's also however, the norm is the 1267. The 1267 should also be on this car rather than the pathetic restamped 1273 that is on it now. In addition to the wrong font, they did not even stamp the correct pick code. I have only documented 2 dates thus far that the 1273's were stamped. This is certainly NOT one of them.
It is a very nice car though!

[197oneTA]

Ok, we got the car and are very pleased with what came. I took some pics of the carb and am hoping sombody can help me identify it. If it is a restamp, it appears they restamped the body of another 1971 455 HO carb..... I don't get why whoever in the past would have done that, but who knows. What other distinguishing marks, numbers, or other things on this carb would help me to narrow down which one it really is?

I really appreciate the help!

[197oneTA]

Here are a few more pics of the carb. including the actual stamped 7041273.

Thanks again!

[blue71ta]

the 7041268 & 7041270 (automatic) carbs were single booster models too...

...so maybe someone started with an auto carb & restamped the last few digits?

[Judge273]

Noted as an auto carb by front extension with rubber. No pun intended.

To make it more confusing rebuilders would take original 273 dated carbs and add the that feature...

Maybe the plant code and date are original? Keep in mind a 263 is a 400 manual carb with the features of an HO carb.

Let's here more about the car and engine!

[197oneTA]

Well, the car looks almost as nice in person as it did in the pictures.... There are a few things that need attention, but it is overall a very very nice driver. The M22, HO Block, heads, intake and exhaust manifolds, that came seperate from the car are all legit and in nice shape. The 273 Carb, so far is the only issue. (see pics in previous post(s)) Any other information that anybody has on the carb to help identify it would be great. There is so little information about these carbs on the net and even fewer pictures.

The engine that came in the car is a real beast! It is a stroked 400 and it has a bunch of power. The headers exit into a 3" exhaust with what must be the most free flowing mufflers made. This thing is way too loud for our taste. Dad decided to go with the engine in the car for now so we are getting some RA 3 Exhaust manifolds and a Pypes exhaust system. He will be slowly rebuilding the numbers matching HO engine for future use. The turbo 400 that is in it now shifts very good. The car came tuned very good, when it is warmed up, there isn't a bit of hesitation.

The body panels are good, the quarters are definitly original. The interior needs a few things corrected here and there, but overall nice also.

Since we built in a certain amount of "scepticism" about the description into the bid we made, and what we were expecting when the car arrived, we were not disapointed at all. In fact, we were very pleasantly surprised.... There is no doubt that dad ended up with a lot of bang for the buck!

Lastly, thanks to those who have posted information, on the previous posts, about the 7041273 carb. Were the carb bodies (besides stamped #'s), or air horns on the various 1971 HO carbs different in any way? I looked at my 267 carb and see that it does not have the "port with the rubber nipple on it" as in the pic. I posted of the 273. Anyway, this is a confusing Carb and we hope to identify it!

the vacuum port on the front of the carb body (the one with the rubber cap on it) is for auto trans applications. As I said, this could have started out as an automatic carb, then had the 7041273 number stamped into it OR it could have been a 7041263 or -267 carb & had the vacuum port added AND the restamp done.

...OR it could have had the outer booster ring removed on each venturi, starting out as a "regular" Q-jet, but I believe the "VE" pick code and "3590" date code is correct for a 7041268 (auto) carb, so most likely it started out as a '71 455 HO/automatic carb, then had the last digits restamped.

[blue71ta]

ok, just checked two original 7041263 carbs & a 7041268 carb I have here. Both of the -263 carbs use the VE pick code (one is NOS, so I know it's legit).

So yours must've started life as a 7041263, had the auto trans vac. port added to the front of the body, then had the last digits restamped to the -273 number.

[197oneTA]

Thanks Blue71TA for checking that out for me. I really appreciate it.

Do you know what the differences are between the 7041263 carb and the HO carbs?

I thought I had a 7041268 carb up in the barn somewhere and have been pulling my hair out trying to find it to compare with the "273" dad got with the car. I couldn't find it the couple times I looked over the past week. I started to think I sold it or something. My memory really sucks and I'm only 44! Well, I just found it and low and behold it turned out to be a 7041270. I knew it was an automatic HO carb and for some reason thought it was a 268.... It does not have a pick code at all. I will compare it to the carb dad got tomorrow and see how they compare. I put a picture of the stamping of the 270 I just dug up below.

Thank you again for your help! I hope that sometime I can give you a hand with something.

[Judge273]

I think performance wise on the HO engine, those carbs you have will give you great kick! Both should flow about 825 cfm or more those. Both (263 and 270) pack some power.

You could run the sr 270 and add RA to your original engine for more performance...

Glad the car is better than expected, as they are fun (smooth) driving torque monsters even with the original HO engines.

As Mike stated, the -270 you have pictured is a Service Replacement, thus no pick code.

You're welcome for the help. Send me a PM if you want to discuss further as there are other "clues" to these carbs when it comes to identification.

Your dad got a great car there, too, by the way

p.s. the accelerator pump rod is in the wrong hole on the -270 carb you pictured (should be on the inboard hole)

[197oneTA]

I talked to dad this morning and he told me he bought that 7041270 carb new, over the counter, back in the late 70's when he was building up the 455 SD/HO engine he put into his 78 TA. I'm glad to here that the 7041263 restamp carb is functionally the same as the other HO carbs, as that carb will end up on the GTO HO motor (non ram air) until we can locate a date coded 7041267 (if dad ever wants to take the GTO that far).

Blue71TA, I probably will have a few more questions and will probably take you up on that with a PM or two.

Thanks again

[Judge273]

Last number on date stamp looks like an 8. 1978 makes sense. 270 sr is probably worth some cash as they were the service replacements for all HO carbs including non RA HO's?

Good luck with the HO!
