No, well depending on what year your 340 is. If its a 72 then yes, otherwise youll need need and external weighted flexplate or converter.

The OE flex plates are exactly the same. The torque converters are weighted differently.
If your 340 was 68-72, use that external balance flex plate.
If your 340 was a 73, then use that same external balance flex plate, but make sure you knock the balance weight off your converter first.

Sorry to hijack, but what if you have a 360 based stroker that was balanced at the machine shop with a neutral balance harmonic and flex plate? Would you still knock off the weights on the TC?
If the machine shop internally balanced your engine with neutral balancer and flexplate ...you dont want weights on anything...
360s are externally balanced ....you need a balancer for a 360....then you need either....B&M flexplate for externally balanced 360 with an un weighted converter....OR stock flexplate and a weighted converter...

That's what I was thinking, but its easier to ask BEFORE you knock those weights off versus trying to reinstall those things.....
