The short answer is "Yes." I'll use my own engine as an example. Originally, my 428 from the factory was designed to be externally balanced. The original flywheel was a special one that is weighted specifically to work in conjunction with the crankshaft. When I had the engine totally rebuilt, I had the engine internally balanced so that I could use any neutral balanced flywheel (and not a special externally balanced one). Balancing an engine is an art, it takes time, and the special metal that is used for plugs is not cheap.
