Engine Configuration
- Engine Type: V8
- Displacement: 302 cubic inches (5.0 liters)
- Compression Ratio: 8.4:1
- Fuel System: Carbureted
- Valvetrain: Overhead Valve (OHV)
- Number of Valves: 16
- Max Horsepower: 134 horsepower @ 3,400 RPM
- Max Torque: 233 lb-ft @ 1,600 RPM
The 1979 Ford 302 engine featured a V8 configuration, meaning it had eight cylinders arranged in a V shape. With a displacement of 302 cubic inches or 5.0 liters, this engine provided a good balance between power and efficiency.
The compression ratio of the 1979 Ford 302 engine was 8.4:1. This ratio indicates the ratio between the volume of the combustion chamber at its largest and smallest points. A lower compression ratio allows for more efficient combustion and better fuel economy.
Being a carbureted engine, the 1979 Ford 302 utilized a carburetor to mix air and fuel before delivering it to the combustion chambers. This technology was common during that time and provided reliable performance.
The valvetrain of the 1979 Ford 302 engine was an Overhead Valve (OHV) design. This means that the engine had its valves located in the cylinder heads, above the combustion chambers. With 16 valves in total, this engine could efficiently intake and exhaust gases during the combustion process.
In terms of power output, the 1979 Ford 302 engine produced a maximum of 134 horsepower at 3,400 RPM. Additionally, it generated a peak torque of 233 lb-ft at 1,600 RPM. These figures provided ample power for various Ford vehicles of that era.
Engine Oil Specs & Service Intervals
Proper engine oil specifications and regular maintenance are crucial for the longevity and performance of any engine, including the 1979 Ford 302. Here are the recommended engine oil specs and service intervals for this engine:
- Engine Oil Type: SAE 10W-30 or SAE 10W-40
- Oil Capacity (with filter): 5 quarts
- Oil Capacity (without filter): 4.5 quarts
- Oil Filter: FL-1A or equivalent
The 1979 Ford 302 engine requires engine oil with a viscosity of either SAE 10W-30 or SAE 10W-40. These oil grades provide the necessary lubrication and protection for the engine’s components under normal operating conditions.
When performing an oil change, it is important to replace the oil filter as well. The recommended oil filter for the 1979 Ford 302 engine is the FL-1A or an equivalent filter. This ensures proper filtration of contaminants and helps maintain oil cleanliness.
The engine oil capacity of the 1979 Ford 302 engine, including the filter, is 5 quarts. However, if the oil filter is not replaced during the oil change, the capacity is reduced to 4.5 quarts. It is essential to use the correct amount of oil to avoid potential engine damage.
As for service intervals, it is generally recommended to change the engine oil and filter every 3,000 to 5,000 miles or every three to six months, whichever comes first. Regular oil changes help maintain engine performance and protect against premature wear.
