I haven't seen you mention Thermoquads. Any experience or magic up your sleeve with the black plastic monsters?

Good morning to all,
The biggest problem facing us today is getting good usable core and parts.
Those carbs were pretty good, but never received the support from Carter.
We used to get the "Track Packs" Chrysler and one of the Direct Connection books and go from there. One problem I found was during service they were exposed to high heat and the Center Sections would warp and even found a few fuel passages shut down. These were mostly street carbs , the racer carbs usually survived much better. I still feel that it was a good carb, but misunderstood by most ( including myself ). Now fast forwarding to today I'd tackel them again, but I'd probably need to molest one or two to see what parts will need to be made or repurposed.
Not trying to HiJack your thread, but the parts problem is universal at this time.
Have a Good Day.

Respectfully,
Henry Kunz 1534 H/SA

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.
