ETA: idk why the link didn't resolve, but it's a spacer specifically designed for the roller cam snout and the eccentric from hughes.

second edit: there's long snout roller cams that *do* have the provision for a pump eccentric. these are typically in the early roller motors and won't fit with the magnum front cover. so basically what i'm saying is open it up and have a look see before splashing 60 bones on something ya don't need.
