Intake and carb
 
2 Attachment(s)
Advertised as coming off of a 1973 Trans Am and priced at $600. What would you do?

JSuchma 03-21-2025 11:41 PM

If it were from a Super Duty, need I say more!

Check #-s on carb and intake.

Is there a pic of the EGR valve?
Can't really see the intake date or numbers, but don't think it is a SD intake, other than the 'X' on it.
Probably an early intake?

It has some of the parts that might be useful to have though?

:confused:

Definitely not an SD manifold

Tellyshavilli 03-22-2025 08:43 AM

My opinion is it’s overpriced but if you need it.

PAUL K 03-22-2025 08:58 AM

I guess it depends on the situation.

If I was looking at this because I needed one. I'd look at all the original accessories and mounting hardware and if I was interested in purchasing. I'd see if the seller has the rest of the parts that are normally bolted to the manifold and make sure the carburetor was correct for that the intended application. If needing to be shipped with the freight prices today and the lacking packing jobs, I'd most likely pass.

If the manifold was being dragged to a swap meet and I had a dolly that was empty I'd offer to lend it to the guy carrying that.

If I owned it and was interested in selling I'd list it on the classified's on this Website.

If it was original to my car I'd restore it.

If it was for a survivor I'd clean it, rebuild the carburetor and run it.

Lots of options

Would also make a nice doorstop

Too heavy and it'd wobble too much. 75-79 versions work much better.

Nope, not an SD intake. SD carb has a tell right off the top. but this carb does have an idle solenoid attached (so maybe 4 speed).

First thing I look for is ID'ing intake. There were three (or 4) intakes for '73, 491244, 492744 and 494282 (early and late). Having the square plug would indicate an early 494282 intake and I think X, not X C(maybe for the changeover). I think I was able to read an A293 date. I haven't been able to tell what is stamped for the different EGR valves to ID usage.
So, yes, first thing to ask is what's the carb number. Turns out it was a replacement 7043266 (maybe over the counter parts dept. purchase). Too much money.

Matt, you think a 7043265 is not worth $500?

formula kid 03-23-2025 11:45 AM

Ok , so looking a little closer at what is presented in the picture. Look at the brake booster fitting. That fitting was only used on non-AC cars. So, the carb if all original wood mean that you have a 7043263 400, or a 7043265 455 both were 4spd set up. Would that change your mind as to price you would pay?

Held for Ransom 03-23-2025 02:52 PM

The 7043263 was used in both 1973 and 1974, which means there should be quite a few out there. That lowers the price of a core.

Not sure on the 400 4 speed equipped Formulas but the 455 4 speed Formula and Trans Ams were available with A/C.The 7043265 carb is a fairly rare one being that only 1,420 would have had that carb.Not sure on the numbers on the Formula 455 4 speed cars.

Question for you:
The 7043262 was used on 455/auto's. What is the difference between the 400/auto's 7043264 and '266 (early/late?)?

unruhjonny 03-24-2025 05:23 PM

I'm pretty it wasn't a lot;

(application number) = (primary jet) / (primary rod) / (secondary rod; doe not number)
'3262 = 71 / 41 / CR
'4262 = 71 / 41 / CR
'3264 = 71 / 43 /DB
'3266 = 72 / 45 /DB
'4266 = 72 / 45 /DB

Idk why but this thread reminds me
Of the old days on PY . It’s good to see this back again it’s been kind of lacking around here for a while. Though I didn’t usually like to get involved. I really enjoyed threads like this one .

Here is what i have on those:

Held for Ransom 03-25-2025 05:42 AM

Thanks. I was more wondering about, because of the emissions bust, did a port get a vacuum signal change or what happened between the two? Would a '264 be better to work with or a '266? '264s stopped in 0313 (or A3) and '266s started in B3 (don't have a good Feb. start date in Julian yet).

The only difference I've noticed is that the calibration was changed due to the updated emission system and therefore a different number was needed on the carburetor.
