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.
