I just re-read your post....were you asking about the "floating" rods? If so, that refers to the wrist-pin bore that the piston attaches to. A floating wrist pin is where the wrist pin has a significantly smaller OD than the bushing in the connecting rod. It is held in by clips on each side to keep it from moving. It's a lot less friction. A bushed connecting rod relies on a press fit for the wrist pin. Sometimes the wrist pin is just different by a few ten-thousandths of an inch.

If you did know that, just disregard my babble. :-)

One other thing...how much horsey-power are you planning on having? You might wanna step up to an H-Beam connecting rod instead of an I-Beam.
