Here at Black Widow Cams we offer the last word in hand-crafted ground camshafts in the world of motorcycling. With over 30 years of experience in the field of engine machining, our ASE Certified Master Engine Machinists have the abilities to meet all your machining needs.

Black Widow Cams possesses all the original Harmon & Collins roller masters along with the original Tom Sifton master cam collection and machines. Within the last 15 years, we have acquired over 1060 masters for both flat tappet-O.H.C. & roller. All of these masters were bought through private sale of owners of the former camshaft companies. We have a master maker to make our own profiles as well as improve on older profiles. With three cam grinders and a CNC machine, we have what it takes to do your cams. We will continue the high standards that we live by " Limited Production ", which means a better product for you and your cams!

These lobes are timed on your cores or new cam cores welded and finished ground to insure accuracy. The reason? A heat-treated lobe can distort up to .003" to .004"+ or all over. Also, welded cams will distort after welding. This is why we can insure you:
