Skunk2 Camshaft Identification Information

After seeing a number of emails and getting phone calls about the markings on the Skunk2 B & H camshafts we thought it would be a good time to create a listing of the old markings of the camshafts as well as the new markings.
All camshafts manufactured and sold starting March 2011 will have the new markings. These camshafts will have the same stamp on both Intake and Exhaust cams.

Camshafts made/sold prior to March 2011 will be hand etched, those made after will be stamped.
