⚙️ Engine Specifications

Engine Code Example:

318 (5.2L V8 Magnum - likely option)

Engine Description:

The D250, as a 3/4 ton model, would typically be equipped with robust V8 gasoline engines or a Cummins turbodiesel. For 1991, likely options include the 5.2L Magnum V8 (318ci) or potentially the 5.9L Magnum V8 (360ci). A significant offering for this generation was the Cummins 5.9L (359ci) 12-valve inline-6 turbodiesel.

Horsepower Range Gas:

Approx. 170-230 hp (depending on specific V8 engine and tuning)

Torque Range Gas:

Approx. 250-300 lb-ft (depending on specific V8 engine)

Diesel Engine Availability:

Highly probable availability of the Cummins 5.9L 12V Turbodiesel (175 hp, 400 lb-ft torque range)

Fuel Delivery Gas:

Throttle Body Injection (TBI) or Multi-port Fuel Injection (MPI) for Magnum engines

Fuel System Diesel:

Rotary injection pump (VE) or Inline injection pump (P7100) for Cummins diesel, often with turbocharging

🔧 Transmission

Standard Transmission:

Manual transmission (e.g., NP435 4-speed or Getrag G360 5-speed)

Optional Transmission Auto:

Automatic transmission (e.g., A727 3-speed, A518 4-speed overdrive)

Overdrive Option:

Availability of 4-speed automatic with overdrive (A518) for improved fuel economy
