fxbill, what a bummer to hear about your engine loss. that really sucks, however I have called both MSD and Comp Cams and they both swear that the cast gear that is stock on the MSD distributor is the right application for my Comp cam. The cam is definetly cast ductile iron that is ground to spec. Take a look at your cam and you will see it is cast with the exception of the machined surfaces. The cams gear is not seperate from the cam as it is also ground from the cast blank much like a engine block or most crankshafts are cast and then machined. A billet steel blank is machined on every surface and shows no dull or black casting surfaces. I think what you expierienced was a part failure due to defect. Give them a call and let us know what you find out.
