2. The small-block had managed to motivate this Blazer for well over 100,000 miles, but the years of poor maintenance had left it as a glorified boat anchor. The first step was to remove the motor and transmission from the vehicle. The original transfer case is being reused and was left in the Blazer along with the driveshaft. When removing the engine it was imperative that we marked/labeled each of the electrical connections and all hardware.
