cam swap on a nnbs/genIV/vvt motor
i am about to put a cam in my truck and scoggin dickey was tryin to tell me you have to change ALL kinds of bs like lifters and rocker etc since its a VVT motor.....
allen @ nelson performance said all i need is a timing cover assembly from an 05-06 gto and the 3 bolt cam sprocket....
who here HAS done a cam on an 07-08 5.3 that knows what really HAS to be done

we have done at least 10 of these, the only issue you run into with the lifters is that if you deck the heads you will need shorter pushrods on the dod cylinders or go with some new non dod lifters. the lifters are longer on the dod cylinders. We opt to just use the gm racing lifters. other than that it is all gravy.....just like allen said
