Enzo is right on the timing cover and water pump, which are better , the water pump has a much bigger bearing , and a fan clutch that screws on, a big plus , also has the extra pulleys on the water pump, only the feedback carb had the different distributor , your exhaust manifolds will fit, the block is thicker and stronger, (hey it's going into a truck) and the cam bearings are larger, also a pluss, order a comp cam for that year ranger/bronco II , use the lower tube that comes with the ranger for the heater hose , it crosses under the crank pulley and not in the way of the A/C compressor,
