We all know that the 4.2 L is awesome. But what if someone needed more power and torque? Are other options available?
If you want to add a little to an existing 4.2L you could add a different cool air intake and dual exhaust.

For '06 it appears that the 5.3L V-8 will be available in both LS and LT trim levels. That will give more HP and Torque. :D
