In short, no. This is quite common to mix up parts and not know it’s wrong. Bud bought a 69 charger with a cast crank and balancer. Problem was it had a std balance flywheel. Vibrated bad enough to beat out the pilot bearing in the hub. If the balancer is drilled somehow enough to offset the weight of the six pack balancer to make it neutral, then yes, or as mention, real heavy pistons were used. I don’t see finding pistons heavier than stock. Now, are you sure it’s a six pack balancer instead of a cast crank balancer and cast crank with ly rods?
