I'm in the rebuilding process of a 401 and have been searching for bearings. I have found out (from a phone call to Performance American Style) that Federal Mogul has bought most of the bearing companies out as well as the newer generation of engines doesn't require the oil hole in the rod bearings, not sure of the mains. I was told I would need to drill a hole and thought it would be nice to have a Jig to place each half of the rod bearings in so the drilled hole would never be off. Plus it would make the drilling process faster, easyer and fail proof.
What does everyone think?
