Help identify a crankshaft.

I picked up some small block parts this weekend off a friend of mine.
In the lot of parts was an un-used crankshaft, it has stock 360 mains, and rod size, and looks to have a 4" stroke, as measured with a cheap set of 6" calipers.
The only makings is some stamped numbers:
7258
233
The crank was in a Scat box, but the numbers on the outside of the box were for Ford junk.
So anybody know who actually made this crank? I know it is a long shot.
