there was some discussion about this a while back. every model A engine that i have taken apart has had the groove cut in. and the last engine i had babbitted was grooved.

thank you

The groove needs to be there to supply oil evenly across surface of bearing and crank along with oil wells.
Ford did everything for a reason and if it wasn't needed he wouldn't of done so.
