The Ford Diesel Pickup Beginning

The beginning of the ford diesel pickup started in 1978 when International started developing the 6.9L indirect injection  (IDI) motor. It was not until 1983 that the motor was offered in the 3/4 and 1 ton trucks, the partnership between Ford and International was made in 1982. The motor was 420 cubic inches and was naturally aspirated (no turbocharger). The 6.9L created 170 horsepower and 315 lb-ft of torque at 1,400 rpm. The 6.9L diesel was known for being incredibly reliable and very simple to work on. It was a solid performing motor in its time and was very popular. The 6.9L diesel was replaced by the 7.3L in 1988.
