This is my 1979 D100 short bed we pieced together from different trucks we took parts off from in Texas. My daughter went down there and bought every thing we needed. I built my own rear suspension using a 3 leaf suspension and a cal trac type traction system. It has a 365 small block with 1.88-1.60 J heads and a .600 lift Comp Cam. A Mopar M1 intake and an 870 CFM Demon carb. A Dynamic 5,500 stall converter and a 904 trans and a 4.88 8 3/4 rear gear with 9x29.5x15 Mickey Thompson Slicks. I turn 7,000 Rpm with it. It weighs 3700 lbs. with the roll bar installed and it runs 11.50's at 114 MPH in the 1/4 mile.
