Bore size on the 5.3l is 96.0mm (3.780") while the 5.7l bore is 99.0mm (3.898"). Both engines share the same crankshaft stroke. I've only heard some downstream info on the upcoming aluminum 5.3l blocks. It will have the DOD technology (displacement on demand) and perhaps share the LS6 head casting with a smaller valve and chamber.
Anyone with more info please post.
