Not all 6.0 cranks are the same...
*The 6.0 crank is balanced differently that the 5.7 according to ARE.
*99-00 6.0 cranks are longer at the rear flange compared to the 01-02 cranks. I verified this yesterday with my 99 and 01 6.0 cranks. The 99 was like .5" longer and would take major machining to get it down to the right size. The 01-02 6.0 cranks match the 5.7 crank in length.
Just a heads up for those that don't know.
