360 Torque Convertor Balance?

The B&M flex plate for the 360 is balanced for the 360, looks like a big cookie with a bite out of it.

It would allow you to run any neutral balance converter. Taking all the weights off of any given converter will not make it neutral balanced. It would need to be balanced to neutral.

The B&M flex plate (truly a misnomer as you will see if/when you get one) will allow you to use a converter from any internaly balanced small block, /6 273 318 and 340's.
