THANK YOU !

The numbers on the back indicate that it's a Crane semi-finished 9310 steel billet carburized core for a 426 Hemi with standard bearing journal diameters, standard lifter bank angle, and standard firing order. Crane sold these to other cam companies, who would finish grind them to their specs, as indicated by the numbers on the front (not Crane). Regards, Chase
