Most truck enthusiasts modify their trucks beyond the capabilities the 4L60e can handle. Eventually, the trans will give out, sometimes multiple times before the owner is forced to find something else. Being that the 80e is the next logical choice, everyone takes that route.
As far as anyone saying that; it just depends on how far you take the 6.0L. To ensure the 60e will hold up, install a shiftkit/servo. This is recommended even for the 4.8L.
