Actually the Duramax is a Isuzu GM own's them. I have seen some of the early 4 cylinder Isuzu's put in pickup's. That version was a marine motor. My freind's like the Dodge Cummins version. Because it is from a truck allready alot of the componets will move from one truck to the other. The first one's that had mechincal injection and 2 valves are the easiest to convert. But I'm no expert for sure. Being a mechinist and fabricator really help's on project's like this.
