Why not use clevite 77 rod bearings and federal mogual mains or the clevite 77 mains when they come out?? Then your covered, they will last well beyond the stock lead(i think) bearings. Throw a DMD on there and if you spin another one I would be amazed. Sounds like very few of those engine built were the duratec's fault, ie bad motor rebuilds, etc. Tri-metal bearings and a DMD will damn near cure the spun bearing problems.
