⚙️ Engine Specifications

Engine Options:

Inline 6-Cylinder ('Stovebolt Six') and Overhead Valve (OHV) V8 engines. Specific displacements varied by year and model (e.g., 216.5 cu in (3.5 L) OHV I6, 235 cu in (3.9 L) OHV I6, 265 cu in (4.3 L) OHV V8 in later years).

Horsepower Range:

Typically ranged from approximately 90 hp to 150 hp depending on engine and year.

Fuel System Type:

Carbureted (e.g., Rochester, Carter carburetors). Specific models and configurations varied.

Lubrication System Type:

Pressure-lubricated with oil pump and filter. Specifications for oil viscosity and capacity are critical.

🔧 Transmission

Standard Transmission Type:

3-speed manual transmission (Synchro-Mesh).

Optional Transmission Type:

Powerglide 2-speed automatic transmission (introduced later in the period).

Transmission Features:

Clutch operation, torque specifications for flywheel and pressure plate, shift linkage adjustments, and fluid requirements for automatic transmissions.

📐 Dimensions

Wheelbase:

Varied by model (e.g., Sedan, Coupe, Wagon), typically around 115 inches.

Curb Weight:

Typically in the range of 2,800 - 3,500 lbs, depending on body style and equipment.

Gross Vehicle Weight Rating:

Refer to specific model year for GVWR, typically above 4,000 lbs.

🛡️ Safety Features

Passive Safety Features:

Lap belts were optional or standard on later models. Robust steel body construction. No airbags or advanced crumple zones typical of modern vehicles.

Active Safety Features:

Hydraulic drum brakes on all wheels, mechanical parking brake, steering system.

💡 Technology Features

Infotainment Features:

Factory AM radio, manual tuning, limited speaker configurations. Modern upgrades are common.

Driver Assistance Systems:

None. Features like power steering and power brakes were optional or introduced later in the period and were considered advanced for their time.

Connectivity Features:

N/A. Focus was on mechanical operation and basic electrical systems.

🔧 Maintenance

Oil Change Interval:

Typically every 2,000-3,000 miles or 3-6 months, depending on usage and oil quality of the era.

Tune Up Interval:

Regular tune-ups involving spark plug inspection/replacement, point adjustment, carburetor adjustment, and timing checks were crucial, often every 5,000-10,000 miles.

Engine Oil Specification:

Refer to manual for specific weights (e.g., SAE 10W-30 or 10W-40, or straight weights like SAE 30 depending on ambient temperature and engine condition). Zinc additive (ZDDP) is highly recommended for flat-tappet camshaft protection.

Coolant Specification:

A mixture of antifreeze and water (typically 50/50) for freeze and corrosion protection. Ethylene glycol based coolant.

Transmission Fluid Type:

For manual transmissions: Gear oil (e.g., GL-4 rated). For Powerglide automatic: DEXRON or equivalent (check manual for exact specification).

Brake Fluid Specification:

DOT 3 or DOT 4 hydraulic brake fluid. Ensure compatibility with older rubber seals.

Chassis Lubrication:

Grease points (zerks) on suspension components, steering linkage, and driveshaft U-joints require regular lubrication with a high-quality chassis grease.

Common Issues:

Carburetor performance degradation, ignition system (points, condenser, coil) wear, brake system component wear (wheel cylinders, master cylinder), fuel system rust and clogging, suspension wear (bushings, ball joints), radiator leaks, engine oil consumption due to piston ring wear.

Body Issues:

Rust and corrosion, particularly in lower body panels, rocker panels, and around windows. Weatherstripping degradation leading to leaks.
