How far can the 5.3L iron block be bored?
And the aluminum block? <-- I believe that one can just be bored to a 5.7L.
Any help would be greatly appreciated folks.

I know you can bore the iron block out to stock LS1 size. Dont know if you can go larger, not sure about the aluminum block either. I would guess you can only hone the cylinders like the LS1 motors.
