well this isnt an lt-1 related question, it more for a truck. i have a 98 gmc z71 with the 5.7 vortec. this is the best place i have found for info about my vehicles, and since the motor is based off the lt-1 design kinda, thought i might get lucky here.

anyways would these rockers work for my truck??
