remove the piston rods from the pistons the ez way on your small block chevy

You gotta weigh each end the rod independently. Big end is rotating small end is reciprocating. Weighing the entire rod tells you pretty much nothing about balancing the assembly

I mostly stick to stock type replacement parts. And if the parts removed are real close to whats going on and no balance related vibrations before I pulled it apart 600 grams seems like a unbalanced rod
585 grams is what I get back from the machine shop. It takes to long and cost 200 to balance a rotating assembly. So if it fails the food scale challenge, or pistons are to heavy. 200 and 3 weeks
Later it goes back together. The 427 build and the 327 got balanced
