Stroke with only Pistons and Crank?

Why are we adding tungsten to an assembly that has LIGHTER PISTONS? The bobweight of an Eagle cast or forged stroker crank is ~2050g. Way over what the stock rods and smaller lighter stroker pistons weigh when balancing. Your gonna be removing weight for sure unless your going to heavy pistons.

That might be what Eagle says ...but...I have had 5 4 inch cranks balanced.....all using Scat I beam rods weighting around 580 grams...Pistons are usually right around 500 grams plus the pins....Everyone has taken Mallory metal...Mine are not eagle cranks 3 are Scat forged steel...1 is a K1 forged steel and 1 is a MP (Scat) Cast crank...

Even the 318 that i stroke with MP cast crank ...Scat Rods and KB Icon pistons weighting 450 grams took a slug of mallory....So that is my real life experience....
