Binding Type Binding: N/A (Digital PDF format) Paper Type Paper Quality: N/A (Digital PDF format) ⚙️ Engine Specifications Primary Engine Gasoline Options: Likely includes GM Vortec V8 engines such as the 5.7L (350ci), 6.0L (366ci), or 8.1L (496ci) Vortec V8, depending on chassis weight class and specific application (e.g., motorhome chassis often used these). Diesel Options: May include engines from International (e.g., DT466 variants) or Cummins (e.g., ISB series), particularly for heavier duty W Series models. Performance Horsepower Torque: Specific figures vary by engine and application. For example, a 6.0L Vortec might produce around 300-325 hp and 370-400 lb-ft of torque. Diesel variants would have higher torque outputs. Fuel System Injection Type: Sequential Multi-Port Fuel Injection (MPI) for gasoline engines; High-pressure common rail (HPCR) for diesel engines. Fuel Type: Unleaded Gasoline for gasoline engines; Diesel Fuel for diesel engines. 🔧 Transmission Standard Automatic Transmission: Commonly paired with robust automatic transmissions like the Allison 1000, 2000, or 3000 series, depending on the vehicle's Gross Vehicle Weight Rating (GVWR). Optional Manual Transmission: Less common in this era for Workhorse chassis, but historically some medium-duty applications might have featured heavy-duty manual transmissions. Features Transmission Control: Electronic transmission control modules (ETM) for automatic transmissions, providing optimized shift points and diagnostic capabilities. 📐 Dimensions Exterior Wheelbase: Highly variable depending on specific W-series model (W42, W52, W62) and intended application (cutaway chassis, stripped chassis, etc.). Wheelbases could range from approximately 100 inches to over 200 inches. Weights Gvwr: Gross Vehicle Weight Ratings typically range from Class 4 (14,001–16,000 lbs), Class 5 (16,001–19,500 lbs), to Class 6 (19,501–26,000 lbs), depending on the specific chassis designation (W42, W52, W62)....
