According to my Canadian Fast Moving Parts Catalogue, 68 6333N denotes front/centre mains, .020" u/s on crank, 2.670/2.671 main bearing bore.
However, 68 6333X denotes .020 u/s on crank, 2.585/2.586 -.[015 O/S] main bearing bore. This however is, I believe, a misprint and should read 2.685"/2,686".
Not much use to you eh?
