Owen, and anyone else wondering, Well, technically speaking, one COULD order a 300C with Code 250 or 260 motors which are both 325HP hydraulic lifter motors. The valve covers I listed as 1851 720 are probably the non-dimpled style for the hydraulic lifter motors. Thanks, Owen for the question which helped clarify that.
