Which Quadrajet Does Your Truck Have? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Sand Wrench** · 12-24-2020, 03:28 AM

Hey guys, I'm interested in starting a thread to track which part numbers of Quadrajet were installed on Chevy trucks, haven't been able to find a previous thread about it. Please include year, engine, transmission, and whether it has California Equipment listed on the SPID sticker. I'll start with my daily driver, it's a 1971 C10 with 350 engine, automatic, built in St Louis with no California equipment. It has Quadrajet P/N 7041211. The "1" at the end of the number indicates manual transmission, but I believe this to be a factory installation, it uses a 90 degree port in the intake manifold for transmission modulator vacuum. Let me know what you got, thanks!

Where’s the pic of the 90 degree port?
Vac tree’s are used for other things too.

And a pic of your carb throttle linkage helps.

-
In the back of the Chassis Service Manuals it lists all of the carburetors used for that year by number. It breaks them down by engine, transmission and whether they have the Air Injection Reactor or not. It also gives the specifications for each carburetor.

The manuals are available for download here:

It wouldn't hurt to read the last page of the thread to see about extra info or updates.

Guys, just remember, all for sale or want to buy posts must be made in the correct parts for sale forums and you have to be a Premium (paying) member to sell items on the board.

Thanks,
