Usually an engine that's been worked on has had the internals balanced
(rods,pistons, crank) prior to assembly. An external balanced engine
uses counterweights on the converter or harmonic balancer. Most of
the time... Unless the engine builder is a complete idiot (experience
from a 340 project Im working on).
