The FE motors (390 included) were/are real reliable work horses, but I agree on the fuel part! The 1989 truck you posted a pic of is what I was talking about. I love the way those early 1st gens look. Those early cummins were Non IC (not intercooled), while the trucks after 1991.5 recieved an intercooler. The benefits to your 89 is 1. It's pretty 2. It has bigger injectors than later 1st gens (more power potential) 3. injection pump flows slightly more than later 1st gens, and 4. Has more desirable pistons.
