Call me crazy but I have decided to build a top hat 4.0 for my 98 landrover discovery 1. I have built engines before and usually have know problem finding the information to complete a build but this vehicle is a little special. I have a copy of the RAV overhual manual and the landrover shop manual. They cover just about anything you want to know about this vehicle, but how to set the timing on the engine. I have looked through both manuals and I cannot find anything on setting the timing on the 4.0. Anyone have any ideas on where to get this information.
