Very good discussion. Keep it coming.

BTW I thought the rod journals on a V8 crank were evenly distributed around the crank 90 degrees from one another. That would mean as far as ballance is concerned the weight at the jurnals would not be relative to the over all ballance. I believe they weigh the rods and match the weight of them. They may bolt weights on the journals equal the the rod weight at the crank shaft end just to get the rotating mass up to what it will be when the engine is assembled. I agree that the piston weight doesn't have anything to do with balance.
