Assuming typical American V8 offerings of the era, this could include engines in the range of 5.0L to 6.6L (302 to 400 cubic inches). Specific details like bore, stroke, compression ratio, and valve configuration would be present.
Performance:
The manual would provide horsepower and torque figures (e.g., 150-200 HP, 250-300 lb-ft torque) for the various engine options, along with guidance on tuning for optimal power delivery through carburetor adjustments and ignition timing. Performance upgrade sections might cover camshaft selection or exhaust manifold recommendations.
Fuel System:
Likely features downdraft or side-draft carburetors (e.g., Carter, Rochester, or Holley). The manual would detail carburetor identification numbers, adjustment procedures (idle speed, mixture screws), and rebuilding instructions using specific kits. Fuel pump pressure specifications (e.g., 4-6 PSI) and fuel filter replacement intervals would be included.
Standard:
If a manual transmission was standard, details would cover clutch linkage adjustment, clutch disc and pressure plate replacement, flywheel resurfacing, and torque specifications for flywheel and pressure plate bolts. Gear ratios would be listed.
Optional:
If an automatic transmission was optional (e.g., a Chrysler Torqueflite or similar), the manual would cover torque converter identification, transmission fluid type (e.g., Dexron II), fluid capacity (e.g., 10-12 quarts), band adjustment procedures, kickdown linkage adjustment, and valve body troubleshooting.
Features:
The manual would describe the operation of the transmission's internal components, shift patterns, and any unique features of the transmission used in the Charger. It would also include recommendations for transmission fluid and filter changes.
Exterior:
While not providing precise overall dimensions, the manual would include specifications for body panel fitment, door hinge alignment, hood latch adjustment, and bumper mounting torque values, critical for restoration and maintenance of exterior integrity.
Interior:
The manual would offer guidance on removing and reinstalling interior trim panels, dashboards, steering columns, and seating for access to mechanical components. It would include torque specifications for seat mounting bolts and dashboard fasteners.
Cargo:
The manual would detail procedures for accessing the trunk area for repairs to the fuel tank, spare tire mounting, and taillight assemblies. It would include torque specifications for trunk lid hinges and latches.
Weights:
Key weight-related specifications would be torque values for critical fasteners such as wheel lug nuts (e.g., 75-95 ft-lbs), suspension mounting points, and engine/transmission mounts, ensuring safe and correct assembly.
Ratings:
No formal safety ratings from organizations like NHTSA would be present for this era of manual. The focus is on the vehicle's mechanical safety features as designed.
Active Features:
Comprehensive coverage of the braking system (hydraulic lines, master cylinder, wheel cylinders/calipers, brake pads/shoes, rotors/drums) and steering system (steering box, tie rods, ball joints) to ensure safe and predictable vehicle control. Suspension tuning for optimal handling would also be covered.
Passive Features:
The manual's procedures for body panel alignment, chassis component torque specifications, and electrical system integrity contribute to the passive safety of the vehicle by ensuring structural soundness and reliable operation of safety-related lighting.
Infotainment:
Basic AM/FM radio and speaker systems typical of the era. The manual would cover troubleshooting and replacement of these components, focusing on electrical connections and component function.
Driver Assistance:
No advanced driver-assistance systems (ADAS) would be present. The manual focuses on fundamental vehicle operation and mechanical systems.
Connectivity:
Limited to basic electrical systems. The manual provides wiring diagrams for the vehicle's electrical harness, enabling diagnosis of any connectivity issues within the vehicle's circuits.
Service Intervals:
Typical intervals would include: Engine Oil & Filter Change: Every 3,000-5,000 miles or 6 months. Coolant Flush: Every 24,000-30,000 miles or 2 years. Transmission Fluid Change: Every 30,000-50,000 miles. Brake Fluid Flush: Every 2 years. Chassis Lubrication: Every 1,000-2,000 miles. Spark Plug Replacement: Every 10,000-12,000 miles. Timing Belt Check/Replacement: As per manufacturer recommendations (if belt-driven).
Fluid Specifications:
Engine Oil: SAE 10W-30 or 10W-40 (API SF/CD rating). Coolant: Ethylene Glycol based antifreeze, 50/50 mix with distilled water. Brake Fluid: DOT 3. Transmission Fluid (Automatic): Dexron II. Transmission Fluid (Manual): SAE 90 Gear Oil. Power Steering Fluid: Automatic Transmission Fluid (Dexron II). Rear Axle Fluid: SAE 80W-90 GL-5.
