Boring out to the 3.6l is a complete waist. It is only .1liters over just the stroke on a 3.2l m104. I know that you are coming from 3.0l but I would not go that far. It will be cheaper to just buy a 3.6 engine anyways. If you find a 350 diesel crank to use. You still have to buy pistons and rods and build the engine. Stock engine parts cost more than 3-4 custom ones. Get a good used 3.6l engine and put standalone injection on it. This will be cheaper and easier. Stock engine parts cost more than 3-4 custom ones.
