Aside from the feasability of a 1 wire engine swap; the Duramax is a damn fine powerplant, Assembled in America despite the Isuzu nameplate..... and has proven itself since introduction in 2001 (let alone being one of the more reliable worldwide diesel manufacturers) . Injector issues from the earlier D-max trucks are also common in almost every heavy commonrail diesel. Just ask the 03-up cummins guys about injector failures.
My idea of full size.
First post, thought I would show a pic of my 2010 Power Wagon...................more to come..............
