Hi,

Can someone Tell me something about these rod bearing in my 383?
Are they standard size?
Is there a date hidden?

I think that those are part numbers and references to the location of manufacture. Look at other parts of the bearing or the other halves.
Stock bearings that I have seen have the name of manufacturer, the date it was made and the size.
STD
.010
.020
.030.

Maybe mic the rod journal and one next to it if you can’t figure out the bearing numbers?

The ink stamp is 0.010 and 7320 is likely the Federal Mogul insert number for set# 8-2320CP or individual pair 2320CP. FM does not usually have a date stamp in my experience like Clevite bearings do.
