The bore, stroke, rod length, and compression height all look great, but without holding it in your hand it's hard to tell. The relationship between the pin, ring package, stroke and rod length (angularity) is going to dictate rocking forces. The skirt length basically triangulates the pin to ring distance to stabilize the piston in the cylinder. Different manufacturers can have different skirt designs limited by weight and crank clearance at BDC. Regardless, a short stroke and long rods will always reduce side loading. Which leads to longer service life and reduces the main cause of block failure.
