The torque converters on cast crank 340's did have a balance weight.
Upon further research, it appears that there were no factory stick 340
cast crank cars. They used a forged crankshaft in that application.
Automatic cars got the cast crank.
To convert a neutral flywheel for cast crank use, you have to drill a
series of holes taking out 4.22oz for a 340, 12.9 for a 383/400/440 and
19.79 for a 360. 440 6bbl cars with the 'heavy' rods used 6.5oz(only in
1970-72). The Mopar Performance Engines book has the layout and sizes for
the holes.
If anyone needs a scan of those pages, e-mail me for the .pdf

I believe the cast crank 340 were only "eccentric balanced" on the front
of
the crank (balancer)....the torque converters and flywheels were neutral
like the steel crank 340s and all 318s. Yes, 360s were counterbalanced at
both ends.

They are the same for big and small block and thus interchangeable. All
smallblocks except 360's and cast crank 340's are neutral balance. Most
bigblocks are neutral balance with the exception of '71-up 383's, all
400's(except stick cars that have steel cranks) and '73-up 440's(again,
except stick cars) that all use cast cranks.

I think I asked this already (old fart's disease), but does anyone have
a 10.5" stick shift bigblock flywheel they'd like to sell? Are big and
small block flywheels interchangeable, and how are the 2 balanced?
Thanks
