Source For Replacement Rochester Quadrajet on 1969 350

[TED DIMON]

The Rochester Quadrajet carburetor is shot on my 1969 with the  Chevy 350 engine that came from the factory when new.
Where can I get a replacement with an automatic choke?  I am looking for an authentic replacement.

Hi Ted- I'd strongly suggest a total rebuild of your original by a well experienced technician.  I'm looking for one too, because I'd like to eliminate the Computer controlled unit  one day, but I dont want different Throttle Bellcranks to the original and I'm not having a lot of luck finding that.  I may relent eventually and try a Chicom Copy...

I adapted a used Quadrajet taken from a ‘78 Buick for my ‘83 Avanti everyday driver.

I did this to eliminate the troublesome electronic factory Quadrajet which seemed to have a mind of its own!

After rebuilding the Buick carb with a zip kit and new composite float, it dropped right onto the stock factory manifold with no major change to the throttle linkage.

Biggest challenge was adapting the electric choke from the ‘83 carb to the ‘78 carb…. which wasn’t hard to do.

Factory air filter assy dropped right on.

The distributor also had to be changed from the stock electronically controlled advance type to the earlier Chevy vacuum advance type… again very easy to do.

I made this change approximately 400,000 miles ago… and have never looked back!!
