Does Crank Stroke Affect External Balance

So I bought the How to Build Big Inch Mopar Small Blocks Book by Jim Szilagyi and in the back of the book there are like 6 engine builds listed with all the details. One engine build uses a cast 4" stroke crank and a stock 360 external dampner to build a 408.

If this is the case then does the stroke of the crank not affect the external balance?
