| 4.1 vs 3.8 Just a little info I ran into on my build. The production 4.1 uses a different size cam bearing than the 3.8. I found out the hard way and now I have to wait for the 4.1 cam bearings to come in which is holding up the assembly of my engine.  Anyway be prepared for this if you are going to build a 4.1. |

| Appearantly the difference is in the years. The cam bearing that were to big to go in were for a 20 bolt pan 3.8. The bearing that fit are for a 14 bolt pan 3.8 or 4.1. |
