What bearing's and rings to run in my 440 Build

IMO, Kings are the best but overkill for what you're doing. The Clevites are fine. I've used Clevite or Durabond on the cam - no problems with either. As far as rings go - a file-to-fit performance moly top ring is fine. Check the pistons to be sure but I believe they use the parger factory ring thickness too. Make sure the shop you use knows what rings you will use as they need to leave the cylinders with the right surface finish
