I'm on the forum for my '70 C-10 but here is the S-15 I built when I finished college a good while back... Shaved door handles, emblem holes, antenna holes, bumper bolts, convertible kit and 350 HP 355 V-8. Built 350TH tranny with a 3,800 stall converter and 3.73 rear-end. That was a fun truck! I used to give the 5.0 mustangs a lot of grief.
