Carburetors
I have a 69 RS SS Z11 Pace Car with a 350/300 automatic with a Build Date of 3D. My protecto plate shows C for Carter so I'm presuming (1) I need a Carter built carburetor 7029202 with a B9 date code verses a Rochester 7029202 with a 4 digit date code. (2) Is there a specific differentiation of the 6th digit code of either 0, 1, 2 aside from indication it's a Chevrolet (3) what distinguishes a carburetor for a Camaro verses that of a Chevelle using the same 7029202 (4) I saw a chart once that indicated a 350 300 hp automatic should have a DH code but will that be on a Carter or a Rochester.
Sorry for all the questions, but I am trying to learn. Thank you for your responses.

Carter Carburetors
The Carter "YF" single barrel carburetor was used only in 1967, and only on the six-cylinder engines with A.I.R. (Air Injection Reactor, aka "Smog"). Other than this application, no other "Carter designed" carburetors (AFB, AVS, WCFB or Thermoquad) were ever installed from the factory on a first-generation Camaro. However, Carter was also licensed to build the Quadrajet as a secondary source, and supplied carburetors to not only Chevrolet, but other GM divisions as well. Note that all Carter-built Quadrajet carburetors will have the same part number and ID number as the Rochester-built Quadrajets, but will have "MFG BY CARTER CARBURETOR FOR GMC" cast into the carburetor body.
