i just got my 847 cam from gm performance parts direct.com and i opened the box and on the cam card it says crane cams 841 grind.i think the specs are exactly the same for both cams, but do you guys think gm has crane cut these cams now ,or did gmperformancepartsdirect.com mess up my order?does anyone know if the grinds are the same?
