Do you balance the rear lighter than the front due to loading the rear on acceleration? What about when you hit the brakes. In a
Formula 1 dry-sump world, pan efficiency might correct some of those issues, but in our world, we can only guess. Does your balance guy use one, two, or three percent overbalance? Does he really know what's correct 'cause the bearings might look good in all three cases?

Grumpy Jenkins used to put 70 gram heavier wrist pins in the race engines and put them on the dyno. When it came time to go racing, he put the light ones back in. If 70 grams per rod end weight didn't cause problems for the Grump, four grams per journal certainly won't. Don't worry about it.

Back in the early 90's I worked the great Smokey Yunik on an engine development project and I asked him about balancing his exact words were ( Balancing is an IMPERFECT SCIENCE) I think that is an understatement to say the least.
