Carter-built Quadrajet?  Sure, I believe that.  I've got a Carter-built '6262 just like yours sitting on my work bench RIGHT NOW, in pieces.  Should have been completed long ago, but I popped the head gasket on my daily-driver, and that's taking up all my time.

A Carter-designed carb on a '70 Pontiac?  I'm not so sure about that.  The guy says he wants to remove the Carter, and install a Quadrajet.  What's he got NOW??? An AFB???  AVS??? Thermo-Quad???  Edelbrock Carter-clone???

 Dean,
 Yeah, I do believe the fuel bowl in the Thermoquad was made out of plastic. I could be wrong though. ;)

Cliff Ruggles:
Phenolic resin from what I can remember?  Those carburetors have great potential, but poor parts support, and whoever designed the choke, fast idle, and other linkages was on LSD back in those days.  I absolutely HATE working on those carburetors for that reason.

They are also too wide for a clean fit in many applications, rear fuel inlet, and too high in the casting to clear most factory Shaker, Ram Air, or aftermarket drop base air cleaner set-ups. 

This makes the q-jet a better option, as it has PLENTY of parts support, and much more compact, with a front located fuel inlet low in the casting......Cliff

Sorry for the confusion.  :-[
The car came with an aftermarket Carter carb and an Edelbrock Performer RPM intake.
And thanks for the info. Just emailed the guy about the 204 carb. See if he still has it.
