(If you'll notice, the overlap is exactly the same on these two cams)

I don't understand. Looking at the FE cams specs, I would have thought the second cam would need a LSA of 112 to make the overlap identical.
regarding the 351 cams, I would have thought the 2nd cam would need either a LSA of 116 or 112 (depending if took gross lift duration or at .050) to have the same overlap.
