That's what I was told some years ago, but I never measured one. The story was GM went with a tall block casting to be able to increase the stroke over a 7.4L and not have rod angularity problems. The 8.1L does not have a 4 ring piston like a tall deck Mark IV but does have a .25" longer rod.
Now I am confused!
