Don't mind me...I’m just biased and tend to embrace technology, the low end and top end efficiency of VVT can’t be denied. VVT CAM will better compliment a stock stall, another selling point for me since I tow 8k lbs in the summer. I keep hearing great feedback about Geoff, i'm going with EPS once I have 5k miles or so on my motor. I'll post the Stage2 CAM before and after results once completed...

I'm glad all of you have chimed in and bring up some points. I guess I would like to keep the vvt since it has both good upper and lower end since this is a 4x4 obviously lower end is important. I'm here to find out if I need to change the verter or not, how will it affect the 4x4 system? this truck is 90% pavement pounder 10% dirt roads. getting a spec'd cam is a good idea, but prob isn't a necessity if it costs a lot more. Also with changing the cam, am I correct that I will definitely have to change from stock springs and also change phaser.

The stock valvesprings have 220lb open seat pressure and handle .501" valve lift (stock) in the L92, so if you're putting in a much more aggressive cam you'll want to match stiffer springs.
Pushrods would be something else you'll want to consider.
