Do a little bit more research and you will find that rod length has NOTHING to do with cubic inch of the motor. Its all calculated with the bore size and stroke, which you will find the volume of each cylinder x 8 = CI. The only thing the rod length has to do with is calculating your compression height of the pistons.

Rod length has nothing to do with determining displacment. The bore, stroke and number of cylinders determine displacment. The LS7 has a 4.125" bore with a 4.00" stroke and has 8 cylinders. The rod length only determines the distance the piston is from the crank throw centerline.
