Nice truck, I built mine 5 years ago and love it. Mine started life as a d350 long box 360 auto with 4.10 gears. It got 11 mpg and could hardly get out of its own way. Now its a 4x4 with 3.55 gears, 91 12valve and Nv4500. The truck gets a best of 21 mpg and pulls like a freight train. I'll never go back to a gaser in a truck unless it's a toy!
