Dad just bought a 03 5.9 with a blown engine. I have a 97 5.9 with a built motor that's been sitting since I bought my 6.4 2500. Wanted to donate the engine, but he is saying the 03 5.9 has a 4 bolt motor mount vs a 3bolt motor mount. I know the front accessory brackets will need to stay with the 03, but I don't understand why there would be a change in the 5.9 for just the one year, doesn't make sense. Any thoughts? Can a 2nd gen longblock work on the 3rd gen 5.9?
