Anyone have any idea if the phenolic body actually did anything? It didn't seem as if the cars that were using them were any quicker. And also, nobody I remember followed their lead.

Good morning Dan and to all,
Those are all great points, and I now wonder if Carter was trying (at the time) to find an improvement in keeping the fuel in the fuel bowls cooler.
Using the Phenolic was a way for Carter to reduce the temps and have a ridged material that could stand up to heat cycling of a passenger car engine. Its too bad most of us working on those parts at the time weren't issued a warning on how to properly tighten those carbs with a torque wrench. Like the Q-Jet at the time most were over tightened and crushed.
Just some of what I have observed over the last 45 years.
Have a Good Day.
Respectfully,
