I am looking to swap out the Turbo 400 behind my 4bt,
and replace it with a AA torque-splitter and a GM465 that
I already have. I was wondering what company's out there
make a standard flywheel for the swap or do I go to the dealer
or junk yard?
Also, will a 6bt flywheel from a Dodge work behind a 4bt and will there be any
issues with the pilot bearing so it would fit the GM tranny?
Thanks in advance.

6BT wheel should work just fine as both engines are balanced...

there should be a readily available pilot bearing, but you can always use a bronze bushing
