I recently aquired what I thought was a Crane Cam. The box is a Crane Cams and has a sticker on the end stating 139631 HR-288-25-12-IG HYD ROLLER CAM W/IRON DIST DR GR The only identification on the camshaft is are numbers 900728and 6209. I checked the Crane website and they show two examples, under the camshaft identification section. Both of these examples have the part number, grind number and Crane Cams stamped on the end. Do all Crane Cams have this type of marking? I am wondering if this really is a Crane cam in the box? Any help would be greatly appreciated.
Thanks,
David

I guess you could mic the lobes and see if they match the lift of the Crane Part #.

Thanks, I plan on doing that today. I was hoping that someone familiar with Crane Cams would know about the markings.

Email this guy, he was at Crane for 22 years in R&D.

He can tell you exactly what you have.
