Internally Balanced 360 Cast Crank

They can tell you if the know how big the slug was. I used to have a chart that showed the weight of tungsten but I can't find it.

A 1x1 slug of Mallory would weigh X amount, minus the material revved from the crank gives you the net gain.
Yes sir, that is all correct. I can compute it all out. But I don't know how big the slugs are or any other adjustment. I was hoping that 70aarcuda was given that info; I'd like to know how close it was to start with.
