1999 Ford Trucks Super Duty F-Series
Powertrain & EngineFord offers a choice of three engines in the SuperDutys: the 7.3L PowerStroke Diesel, and two overhead-cam Triton powerplants - a 5.8L V8 and 6.8L V10.
The 7.3L PowerStroke Diesel is the largest in its class putting out 235hp@2,700rpm and 500lbs-ft of torque @ 1,600rpm for low end towing muscle. Ford claims that you can pull a full rated load up a steep grade, at extreme temperatures, at any altitude up to 10,000 feet. Not too shabby. Both a 6-speed manual and 4R100 automatic transmissions can be coupled with the PowerStroke.
The 5.4L SOHC* V8 Triton puts out 225hp@3,600rpm and 330lbs-ft of torque @ 2,700rpm. The 6.8L SOHC* V10 Triton puts out 445hp@4,300rpm and 415lbs-ft of torque @ 2,700rpm. Both Triton engines are made to travel 100,000 miles before a tune-up is needed under normal driving conditions as long as you change your fluids and filters regularly. And if you get into towing trouble and lose all cooling fluid, the cooling system will automatically sequence alternate cylinder firings to help protect against damage and let you 'limp' to a service station.
