Here are the shots of the engine as promised. Changing my motor from a G54b to the 6G72 in my bio was immensely satisfying by the way . I only wish that I could select the G54b as the 'former' engine, if only as an homage to that gutless wonder.

It isn't quite routed how I would like just yet, particularly on the passenger side. Also note the unmounted MAF, washer fluid reservoir, and coolant overflow. Had to get it on the road in a bit of a hurry. The cruise control isn't mounted yet but after I fab up a bracket it will be going between the battery and brake booster. The hole in the firewall is the windshield wiper motor's spot, which still needs work on the mounting plate. All of these things are going to happen periodically over the next few months as side projects until I have some time to put the turbos on.

Thanks DroppedMitsu, and believe me I can't wait for the forced induction either. I'll keep the updates coming as they happen. There is precious little info on our trucks and I intend to add my own experiences to our knowledge pool for future owners. I'll tentatively say that It should be twin-turbod by this time next year.
