I know very little about thermoquads but I have always loved the idea of them.
I recently got a thermoquad in a "parts lot" and I need help identifying its size and any other info that might be useful. I tried looking at the number behind the throttle linkage (pictured) and half the of the digits have been rubbed off.I think I am reading "3035S, 232 5" but when I try to look these up online I am not getting anything specific. What is the normal ranges that Thermoquads are numbered in?
A little back info, this was supposed to have come out of a running and driving mid/late 70s (74? 76? 78?) dodge motorhome with a 440. But I have no idea if it is original to the engine or not.
I included the # on top of the carb (6-2141) but to my understanding, that isn't specific to any thermoquad
Any help would be appreciated.

Thank you guys, I was convinced it was a 3 but I couldn't find any info on that. It being a 9 makes much more sense!
 
Looking at your suggestions and reading the chart on the website, it seems like the big difference between the 9035/9055 would be the primary bore size?
If this is true and I am measuring at the right point, it would appear like I have 1 3/8" primaries meaning I would have a 9055. Which would be a small block thermoquad correct?

[1] Yes. 1 3/8" pri bore is the 'small' TQ, 800 cfm.
[2] All production TQs have a number that starts with 6 or 9, except for the rare 1971 only model which starts with a 4.
