This brings me to something I've wondered about for a long time. I was racing a 70 340 Duster with the metal AVS. Shortly thereafter (the next year?) Mopar moved to the Thermoquad, and the main point I got from it was rejecting heat better than a metal casting. Looking back, the whole thing might have just been marketing speak because the change was in order to reduce costs.

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.
