I have a 77 Thermoquad that was recently on the road. Can you use that came off a 440

In the world of reman TQuads, they seem to be "one number fits many/all" in nature. Better, to me, to find one that's specific to what you need, then rebuilt it with a quality kit. The Carb Shop in Eldon, MO might be a good source for the kit and parts.
From my experience, use the thick base gasket (OEM-style) rather than a thinner cardboard one. Seems like the OEM Chrysler kits had a 1/4" thick phenolic "spacer" with a thin layer of gasket material on each side? That was in the later 1970s for a genuine Chrysler "gasket kit".
It's NOT a hard carb to rebuild, either.

I thought I would be able to, but my mechanic has strongly recommend that I stay with a 73 carb -- emissions being the reason.
Thanks,

It's not specifically the metering calibrations in the jets/rods/power piston springs, but things like "fuel enrichment solenoids", and other "fixes" for emissions/drivability situations as the emissions regulations got tighter and tighter. PLUS egr and air pumps.
In '73, you could have the "floor jets" in the intake manifold. These were jets which screwed into the heat crossover passage to allow "a controlled vacuum leak" (as our Chrysler service manager explained it) and "egr" without the later vacuum control. Kind of crude, but worked for what it was supposed to do.
While the fuel line might hook up the same, many vacuum hose nipples would be in the same place, the end result could be non-optimal. The other side of the deal could be actually finding the correct carb number item that's worth rebuilding.
What's on the engine now? Just curious.

A low-quality replacement carb that appears to have been designed for a vehicle with an electric fuel pump. It works, just takes forever to warm up.

Hey, thanks very much, but I installed a Holley Street Demon in her -- seems to have done the job.
Thanks,

I was originally, but the price was right and the reviews were pretty good.
