Horsepower Torque:
Varies by specific engine. For example, the 350ci V8 typically produced around 170-175 gross horsepower.
Carburetion:
Primarily carburetor-fed (Rochester Quadrajet, Carter, etc.).
Oil Change:
Typically every 3,000-5,000 miles or 3-6 months, depending on driving conditions.
Chassis Lube:
Regular chassis lubrication (grease points) every 1,000-2,000 miles is crucial for suspension and steering components.
Engine Oil:
API Service Classification SF or SG, viscosity SAE 10W-30 or 10W-40 recommended for most conditions. Refer to manual for specific engine recommendations.
Coolant:
Ethylene glycol-based antifreeze with corrosion inhibitors. Typically a 50/50 mix with distilled water.
Brake Fluid:
DOT 3 hydraulic brake fluid.
Power Steering Fluid:
GM Power Steering Fluid or Dexron II/III ATF.
Suspension Wear:
Ball joints, tie rod ends, and control arm bushings are common wear items due to the truck's age and typical usage.
Brake Component Wear:
Brake rotors, pads, drums, and shoes require regular inspection and replacement.
Steering Play:
Steering gearbox wear and linkage looseness can lead to excessive play.
Rust Corrosion:
Frame and body rust can be a significant issue, especially in areas with harsh winters or coastal climates.
