No offense but I wouldn't waste my time on a Thermo Quad.
Don't care much for the old Carter AFB's that are now Edelbrocks Performer series.
Now the Carter AVS that is now Edelbrocks Thunder series is a heck of a carburetor to have. They were commonly found on 383 Road Runners and 440 GTX's but could be easily tuned to work on a 340.
I had a 73 340 Cuda with one of those thermo junks, ran 100% better when I swapped on a AVS.
Personally I'd still rather have a Holley.
The 340 6pk engine only came in AAR Cuda's and TA Challengers, but the 340 6pk induction system would fit on any of the small block Chrysler engines.
coe in mo:
273,318,340 all used the same stroke crankshaft and flywheels.
Around 72 or 73 they changed the way the engine was balanced so early and late model parts wouldn't interchange.
360 had a longer stroke with it's own balancer and flywheel.
Around the same time big blocks changed to cast cranks with external balance.

It was an Allis-Chalmers tractor dealership,
