Engine Options 1980 Chevy Truck:
Likely includes 4.1L (250 cu in) I6, 5.0L (305 cu in) V8, 5.7L (350 cu in) V8, and possibly the 6.6L (400 cu in) V8 or 7.4L (454 cu in) V8 for heavier duty variants within the 10-35 series. Specifics would be detailed within the manual.
Typical Horsepower Torque:
Varies significantly by engine. For example, the 350 V8 typically produced around 155-170 hp and 300-320 lb-ft of torque in 1980.
Fuel Delivery Methods:
Primarily carburetor-based for most engines, with some potential for early electronic fuel injection (EFI) on certain higher-optioned models, though less common for 1980.
Available Manual Transmissions:
Likely includes 3-speed and 4-speed manual transmissions. Specific models like SM465 (4-speed heavy-duty) or Muncie-based 3-speeds.
Available Automatic Transmissions:
GM's Turbo Hydramatic series, commonly TH350 (3-speed) and TH400 (3-speed heavy-duty).
Transmission Fluid Type:
GM DEXRON-II (or equivalent) for automatic transmissions. Manual transmissions would specify gear oil type.
Wheelbase Options:
Series 10, 20, 30 trucks offered various wheelbases, typically ranging from 117 inches (short bed) to 131.5 inches (long bed) and potentially longer for larger configurations. Specific dimensions are detailed in the manual.
Gross Vehicle Weight Rating Gvw:
Varies by series and configuration. Series 10 (half-ton) GVWR typically 5000-6000 lbs, Series 20 (three-quarter ton) 6000-8500 lbs, Series 30 (one-ton) 7000-10000+ lbs.
Safety Standards 1980:
In 1980, safety regulations were less stringent than today. Key features would focus on passive restraint systems like seat belts and basic structural integrity. NHTSA ratings were not as comprehensive as modern standards.
Braking System:
Front disc brakes, rear drum brakes standard. Power assist often standard or optional depending on configuration. Anti-lock braking systems (ABS) were not available.
Restraint Systems:
Lap and shoulder belts for front occupants, lap belts for center passenger. Dual-diagonal split systems were common.
Oil Change Interval:
Typically every 3,000 miles or 3 months, though some synthetic oils might allow extended intervals. Refer to manual for exact specifications based on engine and driving conditions.
Tune Up Interval:
Spark plugs, ignition timing, and carburetor adjustments typically recommended every 20,000-30,000 miles, depending on engine and components (e.g., points vs. electronic ignition).
Engine Oil Type:
API SF or SG classification. Viscosity grades like 10W-30 or 10W-40 were common, depending on climate. Refer to manual for precise recommendations.
Coolant Type:
Ethylene glycol-based antifreeze (green color) mixed with distilled water, typically a 50/50 ratio. Specific capacity varies by engine and cooling system configuration.
Common Wear Items:
Ignition points and condenser (if not converted to electronic ignition), carburetor issues, exhaust manifold cracks, U-joint wear, rear main seal leaks, cab mounts, rust in common areas (wheel wells, rocker panels).
Electrical Gremlins:
Aging wiring harnesses, corrosion on grounds and connections, failing switch contacts, and aging alternator/starter components were common issues.
Chevrolet Truck Legacy:
Chevrolet has a long and storied history in the truck market, dating back to the early 20th century. The C/K series trucks have been a cornerstone of their lineup for decades, evolving significantly through various generations.
Third Generation C K Trucks:
The 1980 model year falls within the third generation of Chevrolet C/K trucks (often referred to as the 'Rounded Line' or 'Square Body' generation, though 1973-1979 were slightly different). This generation saw significant updates in styling and engineering, with 1980 introducing more aerodynamic features and updated interiors compared to earlier years.
Manufacturing Locations:
GM assembly plants across North America, including but not limited to Flint, Michigan; Fort Wayne, Indiana; Oshawa, Ontario (Canada).
