Shame, because if they'd taken the time to really learn about them they'd have discovered that the Quadrajet is probably the finest street-use carburetor ever designed.

I could not agree more!! I was fortunate enough to be schooled by a much older GM tech ( at the time) taught me all the tricks on those. BTW - there are many different versions / part #'s. Makes a huge difference to have one at least close in zip code to the application its sitting on.
Further - there were actually 800 CFM versions that only came OE with certain hipo Pontiac / Buick / Olds. Those are the ones to use in performance street engines larger than 400 CID.
