TQ carburetor for a 340 Plymouth Cuda vs Dodge Dart

Yes it will work fine, What book are you referring to? Motors manual? FSM?

Thank You.

Two different manuals.
One is an original Mopar Produced "1973 Plymouth Chrysler Imperial Chassis Service Manual". The other is a Paul Herd "Challenger & Barracuda Service Restoration Guide".

Both cite the part number as 6319S being the TQ carb for a 1973 Cuda - Auto Trans - Non California Model
