A slight twist on floating pins, when I had my 292 balanced the small end of the rods were to heavy and since I had selected rods with minimal balance pads (since GM aims to get the rods within a given weight tolerance a small balance pad means that their is more metal in the beam and less in the balance pads) we had to take the weight out of the pin by shortening the pin in order to balance the rods as there wasn't any metal left in the small end blaance pad. So even though the pistons were set up for floating pin we put them in a pressed pins. Just made sure we had good pin to piston clearence.
