Guest Russ240z Posted March 31, 2002 Share Posted March 31, 2002 I have a sbc 400 and need new rod bearings. The ones that I took out are Clevite/Michigan 77. I need to know if it is a standard size or .010 bearing so I can replace them. Here are the markings: 9 87 CB663P F1 The "F1" is the part I don't understand. I have used all my sources and have had no luck. Any help you can offer is appreciated. Russ Quote Link to comment Share on other sites More sharing options...
