Bob. I have balanced several sets. It only took several grams to get the heaviest down to the lighest. The flash that is removed along with some from the very bottom is not functional.
I'm sure someone else has a more definitive answer.

Subject: <VV> Rod caps and balancing

I have a set of .40 over cylinders and forged pistons that I've never  used.  
The rods and pistons were balanced.  I have always been a  little unsure 
about the fact that the rod cap casing ridges were ground down to  balance them.  
I've only completely rebuilt one engine before and that was  stock without any 
balancing beyond weighing pistons to get a close weight  match.  And I 
probably only have one more that I'll do in my Corvair life  (unless I get that 
garage of my dreams) and I'd like to use these .40 over jugs  in a new engine this 
year.  Anybody with experience building performance  engines have any 
recommendations or guidance as to how much rod caps can be  ground before they become 
too weak?
