Actually No.... the 6.0 cam is slightly bigger just not big enough to go through the trouble unless you have a 99.

Edit The 99-00 have the same cam as the 4.8/5.3 it's the 01+ LQ4's which have the slightly bigger cam.

This is correct! I raced a 2001 z71, 4.8, manual....identical to my truck('99 5.3,auto.) except for engine & tranny. Went from a stop, got him to my rear bumper, that was the best I could do.
