Hello im new here. I have a 1993 dodge dakota ext cab 4x4 with 3 inch suspension lift. Has 3.55 gears. The trans just took a crap on me and we have a local diesel shop that ill be working with to put a 4bt/47rh into the truck. Im wanting to build it but I wanna do it from a different stand point. It will be my daily driver so I wanna build the motor for mpg and reliabilty and just gain power as a side effect. I basically just want the motor to run as effiecently and healthy as possible. How would you guys build it? Please give a little more detail than u normally would as Im just getting started learning about diesels. Thanks so much.
