Just out of curiosity, why would you want to go from diesel to gas? Diesel is cheaper and diesel engines generally tend to get better gas mileage than gas, especially in a truck that size. You are going to have to put a new computer in it and re-wire the truck if you go efi. Are you planning on going efi or carb? If you dont worry about smog and dont care about mileage, go carb. They are cheaper to upgrade. What size engine are you planning on going with? Whatever you use, pull the brain, or computer, and the wiring harness when you do it.
