It is an interesting engine. 95th percentile handles nearly everyone that uses it for something less than a hard core work truck. I am thinking that the top 5 percentile would be hotshots, people that constantly tow heavy around town, etc. Since I am one that tows a lot, but have had no problems with my 6.0, I am curious how this engine would work for me. I do like the power outputs, though.
Since they have the standard 12 bolt SAE transmission mount, I see that there are a lot of possibilities for transmission transplants. If you have to have a manual, which I think is silly with the current technology, there will be choices out there, if you want to transplant.
