440 HP(Six pack rods)

So I bought some stuff and got part of it today. The rods are 6 pack rods. Not really that big of a deal and yes I know it takes more power/engine stress to run them. But its what I got now. I got the Forged crank, rods and balancer. I once heard that 6 pack rods take a special balancer is this true? If so what do I need to look for?

i dont know the answer to your question...but i dont think anybody would ever notice the difference in six pack rods vs any other....cept maybe aluminum. i mean....if six pack rods were so horrible, why was the 69 1/2 road runner the fastest car of it's time? huh? everytime i hear or see somebody doggin six pack rods i just laugh.
