Help Identify Competition Cam?
It appears that the springs are also competition cams #918, right? Based on what I found with valve springs & pushrods, it appears that the cam is more likely from Competition Cams and the only markings I could find was "121" and "00" below the number "121". Is there a way to identify this Cam? There's a dab of white paint near the front of the cam on ungrounded part.
With this cam, the engine runs rough at idle, sometimes stalls.
