Denny - I still don't know why you advocate pulling the motor. He figured out the pan and the timing set change out is easy once the water pump is off and a heluva lot easier then pulling the engine and risking breaking exhaust manifold to pipe bolts or even manifolds, drizzling transmission oil, power steering fluid and even dumping gas just to name a few aches and pains. A '70's Ford P/U has lots of room to work to even change out bearings once the pan is off
