As wore as the engine is I would suspect it will need boring all cyls.

DO NOT damage the rod if at all possible! They are weight matched as a set at the factory so keep all eight together. Kill the piston instead. The rod bearings are full floating so are subject to wear on both surfaces. The bearings are available in various combinations of oversize outer diameters (the rod is bored/honed oversize to match) and undersize inside diameters (to fit a reground crankshaft). The flanged rod bearings are on ebay in various sizes. Get everything measured before ordering bearings. It's amazing how well these full floaters hold up. You may not even need new ones.
