Rick,
100% correct about the roar from the TQ secondaries at WOT. QJ has the same size t/blades but doesn't have the roar. No other carb like it....

Have to disagree on sound, my 67 396 Chevelle QJ had same sound AFTER removing the vacuum hose from the secondaries, plus the air cleaner lid upside down.
Also never had a problem with the plastic floats, (a wives tale on brass floats)
