I purchased this 87 chevy about two years ago, it has a 1996 vortech 350 with a four speed manual granny low trans., with a np 205 transfer case. GM ten bolt front and rear with 4:10 lockers. It has a 4" suspension lift with 33x14.50 super swamper tsl radials on 15x10 american racing outlaw II wheels. One of the many modifications I have done to the truck is placed a class 5 hitch inside the frame behind the front bumper. This makes the best pull point i'v ever had on a truck. I just ordered a new 6" lift, the 4" was good but the rear had started saging some so I had a good reson to go bigger. i will have pics. soon.
