Some V engines are perfectly balanced - V12 and V16 I think.
There's a comprehensive article here:
This is the most powerful sigfile in the world and will probably blow your head clean off.

Can you warn me before posting stuff like that? That's both bloody
fascinating and seriously head-hurty.

Boxers are best, much better than even a Mitsubishi balanced inline.

Once you have managed inline & transverse, there's no real point in a V4.

Depends on the angle, IIRC, and the Ford version was designed to be
machined on the same equipment as their V-6.
But some in line fours have balance shafts too.
In line sixes need a torsional vibration damper.
