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.

Thanks @ch1ll

There are two 1 ring and two dual ring competition TQ’s. The larger being listed as a 1.000 cfm and the other an 850 cfm.

There are 4 models of the electric choke TQ. All are small primary. There is a MoPar and Chevy variant. Each came with and without an EGR port.

I have used a Chevy arm TQ with good results on a ‘78 - 400B engine. The swap to a larger primary TQ improved throttle response and power very noticeably. The small primary TQ was used on a 340 for a year or two or three….. I forget…. Then it was replaced by the larger primary TQ. Which is favorable for any type of usage.

The small primary TQ is best used on a low powered 360, a stock 340 is OK, excellent on the 318. On a 318, it will perform great for a mileage seeker or a street strip build

You have to be careful mix and match different carbs cause like the article says, circuitry was changed through the years.

Oh yea! The phenolic resin bowls have an easy 4 different models, there not so readily interchangeable.

9190 HD, it could be a non lean burn heavy truck carb, if it is I will visibly have less ports for emissions hoses, and will be jetted/rods richer than a passenger carb mixture.
I've had several 360 HD truck carbs that fit that bill, that worked great on lightly modified 360's

Exactly! Some of the truck carbs do not have all the vacuum hook ups. Trucks were exempt in many states, so the carbs, even later years are good to go.
