They've got to be kidding?
I can't believe that. There would be latitude in their forgings, for instance the Chrysler 6.123" rod would certainly come from the same forging as the Chevy 6.125" rod, with slightly different big end detail.
Their rejection rate would be too high if they didn't have over 0.30" width to machine off in finishing.
The 6.0" rods for the Chevy 6 are fully 0.11" wider in the big end than the V8 rods, but are otherwise dimensionally similar. That's more than you would expect might be possible from specific forgings for rods of the smaller size, but I'm talking about a mere 0.030".
