Two things on that crankshaft, you could have it offset ground down to 2.2 rod journal diameter (BB Chevy size) and increase the stroke to 3,.91 or 3.90 depending on how good your crank shop is and how good your crankshaft is on the indexing of the rod throws, which gives you a lot better selection on rods, rod bearings and use the smaller diameter HD racing wrist pins as well as lightening the pistons and rods up a little. That works fine when you have to bore the block, not so much when you can do bearings and rings to freshen it only, not a new build
As far as Clevite rod bearing on the Tri Metal type bearing try using CB529H, CB 527 HN, CB527 HND part numbers
I have had to switch in the past to King or Federal Mogul companies like speed Pro or Seal Power due to the warehouses not having the Clevite brand bearings in stock
