I've spent the past 3 days searching for this but came up dry. Found lots of other useful info, but not the answer to this question:

Is there a preferred orientation for Manley rods?

One side has the serial number, the other side a slash for alignment(?). The stock rods have an I stamped on them to tell you which side they should face.

Sorry for this kind of question, but it is my first engine build. Likely to have a couple more of these kind of questions before I'm done. Thanks!

 

They are symmetrical.

 

Big end down.

 

Bearing locks to the right. (intake side)

 

 

Power bottom.

 

Thanks, Savington. They looked symmetric, but I did not want to assume they were.

 

 

The bearing notches should be located on the unloaded side of the big end.
