Hello, not all 53 blocks have the notorious problems. I bought a beaten up 1999 dodge that had 400,000kms on it before I parted out the truck to convert my 1997 to a 5 spd manual.
However, enough has happened to 53 blocks to where most people would rather keep their hands off and throw them out or sell them.
Any 5. 9l can be swapped with little to no difference.
