I don't thing it's an actual weight issue as much as it has to do with tolerences allowed.

I'd say it doesn't have to do w/ the tolerances involved as the level of effort put into the balancing job.

ok i was a little vague.i was more interested in tolerances in grams.i have done my 440s & a few small chevys at a friends shop.i've always tried to keep pistons/pins & rods within 2 grams & crank within 5 grams on street/strip engines.
Cab i had a set of LY rods that varied 14 grams on the big end.

some shops seem to have that "it's good enough" mentality. if your shop has different balance jobs for different engine jobs, i'd look elsewhere. we take the approach of either it's done right, or we won't do it.

Matching the weights is the high school stuff. Knowing where to remove the weight from the crank is a whole different game.
