I just read my response and realized an error. I meant 180 degree motors with shared crank journals are not internally balanced.

I don't understand your 180 degree split inline terminology. Are you referring to the Ferrari motor? That would just be a 180 degree V12.

Sounds like nonsense.

I guess then it's really a 180-degree split-inline.
