I pulled the main caps off of a 396 motor to inspect them today and all I found was that they were stamped "5202 lower". Does this give a clue to the size or where can I go to ID these?
thanks

Might be a Federal Mogul number .... need someone with a catalog that shows the individual bearing numbers in the sets.

If the bearings are original, they would probably be Delco-Moraine, but I don't know what the flying 'P' would signify. They are not Federal Mogul bearings because the F-M number for the individual bearings is 3191CP for the straight shells and 3192CP for the flanged bearing. In most cases, undersize bearing shells are marked with a size designation, such as .010, .020, etc.
But, like Chris said, you really need to measure the journals to be certain as to what size they are.
