I overheard a couple of guys at work one day talking about a vehicle they had seen for sale. Both of them liked it and wanted it, but one had no money and the other wasn't really in the market for it. I liked what I was hearing: A Ford F-250 4x4 with one of the new Powerstroke Diesel engines. I asked the guys if they were interested in it, and they were not. I asked about where to see it.
Over the years I'd test-driven a couple of Ford diesel trucks at dealerships and liked them. The trucks I had driven did not have turbochargers though, so they weren't very powerful. The acceleration wasn't much to write home about on those trucks, and they were more expensive than a large gas motor, on account of the diesel engine. So I never really was interested in a Ford diesel, until the Powerstroke engine came out.
The Powerstroke was Ford's answer to the Dodge Ram truck fitted with the inline 6 cylinder 5.9 liter Cummins turbo-diesel engine. Dodge came out with the duo in 1989 and the trucks sold like hotcakes. Ford had a diesel truck, but it didn't have 160 horsepower and 400 ft-lbs of torque like the turbocharged Cummins.
The Powerstroke was introduced in 1994.5. It was a 7.3 liter V-8, and it arrived with a turbocharger and electronic fuel injection. The engine produced 210 horsepower and 425 ft-lb of torque. Torque (or twisting force) is important for towing, and why so many tow vehicles use big block engines. Engines with a longer piston stroke typically have bigger torque than small ones, which are optimized to make horsepower at higher RPM.
