My 422 smallblock build

Any thoughts on this one?
Check out this page from Summit Racing Lunati Voodoo Camshafts 40200733

I have heard that the large cubic inch engines will actually make a cam “seem” smaller than it would in a stock displacement engine, effectively lowering the basic operating range by approximately 500rpm. Is there any truth to that?
The "seem smaller" scenario doesn't hold water. Numbers are numbers you cant bend physic's.
Regarding the Lunati cam - it would work but IMO there are better choices out there. Im with YR I dont care for the split duration.
