I agree, its no theory, its fact. An engine will perform better, live longer and have less stress on all internal components when its balanced.
Ive read articles and spoke with an engine builder who was a long time endurance racer and they used to run motors in 24 hour races and do dyno testing on motors that werent balanced and they concluded there was no evidence that not-balancing as no ill effects on on engine life. I dont disagree that its money well spent, but Ive run motors that werent balanced and I had 0 issues with it. Plus, you really think factory motors from that era were balanced all that well? My buddy used to race 340's in the early 90's and he said he would pull motors apart where 1 cylinder was already bored .010 over from the factory, go figure that one out!

That makes no difference to balance. Piston A is standard bore size and the same piston in a .03 will weigh the same. They make them like that just so you can avoid the rebalance issues if you kill an individual piston/cylinder.
