Now, if you're not too sore at me, maybe you could help me understand something a little better?

If for instance I were to build a 3L. Let's assume the stock damper is doing a excellent job of cancelling harmonic vibrations. If I invested in new forged pistons,new wrist pins, and forged rods, would the stock damper still be "tuned" properly with the changes to reciprocating part densities, and overall weights? What about if I changed a rotational piece, such as lighter flywheel?

I'm sorry if this is all redundant to you, but I'm trying to understand if the undesireable frequencies are more a function of inherent weights, or more of dimentions. ie. The cranks overall length, and length of it's throws, counter weights. Rod center to center length etc.
confused

At the point your engine would be: Yes a new damper would be highly recommended.

Just call me Judge.
