340 cam specs?

All the same- vendor changes and maybe computer smoothed Remember Crane bought one of the Big Detroit grinders (and where are they now?)
All ground by a big Detroit grinder no mater who you get it from
nice reminder of the Blue Racer line and excellent catalog
note the 268-276 number is just an identifier for the factor replacement- it has no basis in reality but is close to .008 so compare with Racer Brown or Engle or others that use .008
.the SAE .004 posted above gives you a hint on how long the ramps are (especially on the close)

Thanks.
So to summarize what your saying, the following cams are essentially the same.
Maybe some small differences in grinding the shape, matl. or manufacturing.
