What could I do with this Thermoquad?

Good of you fish for providing all that info. I’d stick to the 74 and down TQ’s. Don’t even mess with the lean burn or California carbs. Not too hot on the altitude compensator carbs as well unless you live in the mountains. The 71 is big money carb. Will work well on the street. The competition series are race carbs only as the boosters are one ring only. May not give you the throttle response you want on the street. Best of the bunch are the 9800 series carbs that were sold through direct connection but some of them are for Chevy linkage so you have to read the model numbers carefully.

The 9190 and others I would not waste my time with.
