Can someone please ID this carb for me?
7043202 FS 0313

I know it's a 73/Chevrolet/Auto trans but I would like to know what vehicle it was originally installed on.
I dont have the access to decode the rest of the numbers/letters as some of you members do.

This time I asked the rebuilder to doll this one up for me (It's nice to have a spare).. I think he did a great job, the first one he did for me wes a rush job. It was bead blasted but painted silver.
It runs great and this one is built to the same specs but I think it looks pretty much like new.

If anybody is looking for a good rebuilder (I'm in CT) let me know... this guy does very nice work at VERY reasonable prices, he will also tune/tweak any of his carbs .... just drive the car to him and you will drive away with a smile on your face

Thanks in advance!

Wow that's a beauty of a q-jet. Nice find bob.

I don't have access to decode either, but man that q-jet looks perfect. Better than mine even and mine is only like 4 years old.

Lar's Quadrajet tuning paper says "CHEV 73 350 all Auto" for a 7043202. This means it could have been installed on any 73 chevy with a 350 and auto transmission, except a truck. This would include Vettes, Camoros, Novas, Monte Carlos, El Caminos ect...

My book says it is off a 73 Vett with Auto and 190HP

Bob Onit

Yup, but there are other documents that will tell what Chevy this carb was originally installed on
Thanks

Thanks Kal, the guy does great work and If I told you the price you probably wouldnt believe me,.... no core required either but I threw him a 78 truck core I had laying around because I knew he needed truck cores

Bob Onit

WOW! No $hit????

My car is a 73 L48 (190 HP) 4 speed... close enough!
Thank you!
ps: can you tell me what book your reading from so I can see if I can get my hands on one?

Corvette Black Book (Don't leave home without it LOL)

Bob Onit

Thanks bud!

Ill see if I can dig one up on eBay? bookstore? any certain edition?

From the numbers you provided, there is nothing specific to identify this carb to a Vette or any other 73 350 Auto Chev.

The 7043202 FS 0313 decodes as

704 - Rochester Carb 70 - 75
3 - 1973
2 - Quadrajet 4bbl
0 - Cheverolet Division
2 - Automatic Trans

FS - Manufacturing Plant

0313 - Date - 31st day of 1973

This carb could have come off of 190hp vette, but it also could have been originally installed on any other 73 350 Chev exccept L-82 or Truck

Bob Onit

Hmmmm....... good thing I diddnt order the black book yet
Thank you

Hey KAL!
Heres a pic of it mounted
Note the studs...Ive been swapping the carbs so often or pulling air horns to try and tweak carbs ...
The studs allow me to do all this without destroying the threads on the aluminum intake

Kalway

Verrrrry nice. Quite a beauty.

Bob Onit

Yeah... too bad you cant see it under the stock cold air induction air cleaner

Kalway

Ey which intake manifold you using? I needa get me one of those.

Bob Onit

Aint nothin special
I just put it on so I could run a Holley
Edelbrock Performer 2101 (I think)

Kalway

I'm running the stock '81, it's aluminum but it's freaking low. Need something with a bit more rise to it.

Bob Onit

And maybe a new hood... or a Sawzall at the least.

I dont think the Edelbrock Performer made much difference in performance on my L48... I installed it so I could run a Holley while I am learning about Quadrajets....... Oops....sorry, diddnt mean to offend any Holley Die Hards....Quadraflops, Quadrabogs
There ya go...... now everybody is happy
