Can an engine that was originally manufactured with babbit bearings be line  
bored or something to convert it to inserts?

Hi DickJ
 
Sure. The rods have to be notched for the bearing insert keeper. Then you  
must find a bearing shell that fits the rod. Check with Egge Machine. They may  
already stock just what you need. If not they can make anything you need. You  
may find an existing bearing shell that may only need narrowing or one that 
fits  perfect as is. You would want to align bore the engine anyway if it's 
that  old. They can machine the block crank journals oversize to fit your new  
bearing inserts. You should have the rods rebuilt and resized also and they  
could fine tune the fit on the shells when they do that. The crank rod and  
main 
journals can be cut to fit the bearing shells also. Even if the bearing is  
larger than the crank journals, they can build up the journals with weld and  
recut them to size.
