I'm about to start the rebuild procedure on a Model A engine that has babbited rod and main bearings. It's going to be a challenge to do the re-pour on those mains, or make the pouring jigs to do it myself if necessary. There are a few places that still rework rods, but the "centri-cast" process Chevy used to spin-cast the Babbit bearing material is no longer done anywhere, to the best of my knowledge. It resulted in a thin, uniform layer of bearing material being deposited on the rod which required a lot less finish machining. The rebabbited rods which are available today are mold-poured, a good, but not original-equipment process.
