340 Crankshaft bit the dust

Thanks for the bobweight values. Another variable is the weight of the Eagle rods. The H-beam rods are heavier than the I-beam rods.
I don't understand why the manufacturers don't make .040 or .060 undersize bearings. Which would be less than a 5% loss of strength of the crankshaft. With the quality of the old Chrysler steel, they'd still be stronger than some of the new stuff.
