My 87 318 still has the stock ... everything running around. BTW, smarty pants, stock REPLACEMENT pistons are built by the aftermarket as STOCK replacements for rebuilds and I would bet there are more of them running around than forged aftermarket setups. That means stock weights, or as close as can be gotten. They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

Is there a trend for the factory weights to be slightly heavy, or slightly light? Who are a few of the best shops in the Eastern USA to balance crankshat rotating assemblies?

I would say the vast majority are. I rebuild probably on average one a month and most still (probably as high as 9 out of 10) have all the stock stuff when we tear them apart I am not causing global warming, I am just trying to hold off a impending Ice Age!
