You don't for the rods. You just turn the journal down and run a Chevy rod and bearing. And it really isn't a "Chevy" rod. It's just a connections rod made to specs GM made up decades ago.
It looks like the Chebby rods and pistons for a 4.0 bore is my CHEAPEST solution otherwise I will have to run a 6.123 Mopar rods with custom pistons
& just do a 60 over or 3.97 bore on my 318 block .
