Unless things have changed in the last few years, the SCAT crankshafts are made from an offshore forging that can be machined and ground to make either a 4 cyl Chevy, Model A, or Model B crankshaft.
Unfortunately for the Model B crankshaft, there is not enough material on the forging to allow machining to Model B connecting rod diameters.
Tom Leib is the owner of SCAT, and very personable. I am sure that he will answer any questions.
