I think the .515 number here is an error, but the point is, it's THERE, so could be easy for it to propagate into a "Blueprint". Still, .515 (assuming 1.73 rockers) is only .524 with 1.76 rockers, not .527. But at least we know the source of the .515 number.
Here is an interesting discussion regarding the C8AX-6250-D camshaft from the guy that designed it.
