I have the rods that came out of the engine im rebuilding, can I reuse them on the new KB203-030 floating pin pistons, the old were press in, will it coast more to set them up for float? can I press the new piston pin on the old rod? what is resizing the rod? scat has a set for 260.00 , is float better then press? also, I already have the bearings so resizing would I have to get a new set of bearings?
