Dropped my 401 block, heads, and rods off at the machine shop this morning. When the machinest checked the rods he commented on balancing and specifically on removing weight. Unlike, Chevy rods, the Buicks do not have sacrificial pads that can be whittled down to equalize weight. So, where is the weight taken from or do the rods have near uniform weights from the factory?
Sure they do. Look at the rods a bit closer and think about it. I hope they don't charge you for research time.
