Re: LT4 hotcam

Changing to 1.5 rockers will reduce gross lift, and will slightly reduce duration (we can argue later if anyone wants to challenge that statement). The change in lift and duration will not change the valve timing more than a degree, and that's what is really necessary to move the torque band.
