The engine code would determine the carb.
What is the engine code?

John, I think you might be confused. My question is regarding 1967 Quadrajets. Carter made Quadrajets, and Rochester made them too.

With that in mind, is there any way to tell by documentation or otherwise, WHICH QJet the assembly line put on the engine? NOT the carb number, but the manufacturer? My thought was it could be either, and there's no way to tell for certain which it was if the original carb is MIA.

It's an XS engine, but I'm not sure that helps.

YEP, confused!


I thought you wanted to know if it had a Qjet or the AFB (or whatever the other carb was)

XS is Ram Air, so it'd definitely be a Rochester.

I was mistaken. It’s a WS, not an XS. Car is a 360HP HO car with 068 cam and MT.

I don’t think there’s a way to tell from documentation if the engine had a Carter on it or a Rochester.

Yeah, I *believe* it could have gone either way with the HO. But
the odds strongly favor the Rochester. And when you consider
the Carter-made units are less desirable castings...

My 7027262 (HO/auto) never had that bypass, it's bowl vent isn't
slant cut either. Also checked three other early carbs (68 Buick,
and 68 Olds) and none of those have the bypass either - both of
my 7029268 carbs do though. HTH.
