Common options from this era for GMC trucks included V8 gasoline engines, such as the 5.7L (350 cubic inch) and larger displacement options like the 7.4L (454 cubic inch). Diesel engines, notably the 6.5L V8 turbo-diesel, were also frequently available in heavier duty models, providing significant torque for towing and hauling.
- Horsepower: Horsepower figures would have varied significantly based on the chosen engine. For instance, the 5.7L V8 gasoline engine typically produced around 200-230 horsepower, while the larger 7.4L V8 would have offered more, potentially in the 230-250 horsepower range. The diesel engines, while often lower in peak horsepower (around 180-200 hp), offered substantial torque, crucial for heavy-duty applications.
- Fuel Economy: As expected for a vehicle of its class and era, fuel economy was not a primary selling point. Gasoline engines would have likely averaged in the 10-14 MPG range in mixed driving, with diesel engines offering slightly better efficiency, perhaps in the 12-16 MPG range, especially when not under heavy load. These figures are estimates and highly dependent on driving conditions, payload, and specific engine tune.
- 0-60 Times: 0-60 MPH times for a vehicle of this nature were generally not a performance metric GMC emphasized. Expect times to be considerably slower than lighter-duty trucks, likely in the 10-15 second range or more, depending heavily on the engine, transmission, and whether the truck was carrying a load.
- Towing Capacity: Towing capacity is a key strength of the C7H042. Depending on the configuration, including axle ratios, suspension, and engine, towing capacities could range from 7,500 lbs for lighter configurations up to and exceeding 10,000 lbs, and potentially much higher for specialized chassis cab or heavy-duty versions designed for commercial towing applications.
- Trim-Level Features: Trim levels for heavy-duty trucks often focused on functionality and durability rather than luxury. Standard features would have included essential instrumentation, basic heating and ventilation, durable interior materials, and functional exterior components. Higher trims might have offered power windows and locks, upgraded seating materials, improved stereo systems, and potentially air conditioning. Many C7H042 models were also sold as chassis cabs, allowing for custom bodywork, meaning interior features could be very basic depending on the original upfitter.
