Hello, I just picked up a '71 'Cuda with a 340 3spd. Its complete
except for the carb. Does anyone have any info on what carb this is
supposed to come with? Thanks in advance!

If I recall correctly, it's pretty unique. The first year for the
Thermoquad and a one year item only. What I recall reading (and it doesn't
make any more sense to me now than it did then) is that it's a "solid fuel"
carbureator. Whatever that meant. I hope someone can straighten me out.
That's a factoid I've known and failed to understand for about 35 years. If
you'll tell us whether it's an A/C car or not, someone can probably give the
correct carb number.

340 THREE speed?!? You mean 3-speed automatic, I assume. Otherwise
that's not an original 340 'Cuda, but maybe a 318 or slant-6 Barracuda
that's had a 340 transplant..

ARe you interested in an exact restoration, or function?

IIRC, the 71 340s used either a Carter AVS or a Holley vacuum-secondary
4-barrel. No Thermoquad until a couple of years later on the 360. I
added a cross-post to alt.hi-po.mopars and I know one of those guys
there can tell you the exact carburetor number for either a manual or
automatic (they're different) 71 340 'Cuda. But a good aftermarket carb
that will look fairly correct would be an Edelbrock Thunder Series AVS.

Carter Thermoquad

Carb number #4972 if standard trans,
carb number #4973 if automatic trans.

Concurring what Lefty & BigIronRam said. Reference:
http://www.mymopar.com/carbguide.htm
Aside from the 6-Pack used on the '70 AAR Cuda (and T/A Challenger), the 340
used a Carter AVS thru '70, and the Carter Thermoquad afterward. Due mainly
to mounting & secondary butterfly valve size differences, the two carbs AND
intake manifolds are NOT interchangeable. The manifold for a TQ will have
much larger openings to clear the much larger secondary secondary butterfly
valves.

Ooops I was off a year on when the TQ came out.

3 speed stick
bolt right in and at the strip. only had to shift twice

I'm not sure about a '71, but my '72 Demon 340 had a Thermoquad from the
factory. You might try www.allpar.com

My friend's '73 Challenger 340 came with a Thermoquad, as did another
friend's '73 340 Roadrunner.
