Marx3:
I came to thinking... the Qjet was such a great succes that GM used it on more or les all their cars from the late 60's up to 1990 ( ? ), but who invented it? who came up with this brilliant design in the first place? I am not talking about what company, Rochester obviously, but who? who is the person?

Ethan1:
The creator of the Rochester Quadrajet was by a man named Donald D. Stoltman. Which he created the Rochester Quadrajet in 1965. Actually, I believe he might have been the brains behind all models of the Rochester carburetors. Pretty smart man, to make a intriguing, well thought through carburetor. :)

Marx3:
Very interesting! Thanks :-) it seems he was involved in several patents

If you've ever had a Carter AFB apart, you'd see several similarities with a Q jet. It's like someone took some of those features like jet/metering rod combo, air valve secondaries, and larger secondary bores to a higher level.

Marx3:
I've had plenty of those apart, never thought much of them. They are "rough" by design I think.
I have always been aware of the obvious similarities. It is safe to say the Rochester took those details to a WHOLE new level :-)
Btw, the secondaries on the AFB aren't that much bigger than the primaries. I think the layout of the barrels is more like a Holley than a Qjet.
