Engine tear down good news and bad

[bigfella]

Started geting ready to do my swap 3.8 to sbc 350. I tore into the engine everything looks ok time for a re ring and bearing to for insurance. The engine has brand new timing chain ,cam and lifters only thing is the cam has no markings on it only "YH" stamped on the end. I tried googling sbc cam shafts "yh" and came up with nothing . Anyone have any ideas?

Thanks
