Only marking is "WSM" on one of the rear counterweights.
Sure looks like a factory crank. 3.000/2.500.

Is this an Eagle maybe ?

"Ford Racing" did use aftermarket nodular cranks in their later 460 crate motors but, I don't know if that is one.

A lot of 3Y crankshafts are unmarked per se, but they do have "identifying marks" so to speak.  If your cast crankshaft looks to be OEM but is not marked, then it is a factory 3Y external balance crankshaft if it has the two, 2cc square nodules on either side of the forward-facing cheek of the 1-5 crank throw, as pictured here:

As usual, the rod throws will be barely drilled (compared to the internal balance crankshafts)
