Re: 327 gm bearing Question
Those markings indicate the material and the manufacturing date. The only time GM put sizes on thier bearings was occasionally when they were a "select fit" bearing, like .001" etc If the rod journal is 2.100 that is standard but .... you really need to have it measured with a micrometer, not a caliper.
