I wouldn't worry about it. I would either get your crank cut (reconditioned) so all the mains are the same size, and all the rod journals are the same size. That way you will know the bearing surfaces are good. Buy a new set of main and rod bearings in whatever size the shop says to use. Or just buy a "crank kit" that comes with the crank done, complete with bearings. What year is the engine?
PS: Make sure you get at least that one con rod reconditioned.
