good evening everyone.
i had a couple questions about my crankshaft in my 440
it has r010 on it - rod bearings 10 under.
other than that it has a "b" in a circle.
and a lowercase f on it.
no part number cast into it.
im pretty positive its a forged crank, as it has the skinny forged damper and never had problems with vibrations. standard "ly" rods.

anyone know why theres no part number on it?

its weird. it has the wide flash mark - indicative of forged.
but in the journal by the flash marks theyre are holes drilled straight through.
which ive only seen on the cast cranks.?
