360/400 torque convertor

I am almost 100% certain no.

Also another tidbit. Not all 400s were externally balanced, as some had steel cranks.

steel crank 400's ?!!! truck motor maybe?? I didn't know that, but I admit I have never fooled with any B B except 383, 440. had a few hemi's in a pile of parts and always sold those deals off to "money" guys ! i'm buying the 400 from friend, havn't picked it up yet.
its going in 67 Bel 1 post car, will be just a fun driver, with low compression and maybe enough torque to provide a little fun!? lol
its not on my plate to have to build a trans and buy new convertor. looking for just a decent used set up.
