Power and torque talks... displacement is secondary. What power/torque is each kit is making? displacement in theory suppose to help with torque but it is all in the metallurgic/materials, weight of the components(piston/rod), angles, openings, timing, compression ratio, cooling of the head, shape of the head, piston rings, piston shape(design in general).

Both brands are incredibly so it is a win-win already.
