I don't have my reference books here in front of me but I believe the crank is the same in the 4.8/5.3/6.0/5.7 gen3 engines, all have the same stroke just different bores.
Oh, forgot, the 99-2000 6.0L have a thicker flange on the crankshaft than all the others. Uses old style transmission/flywheel.
