What engine does a 1979 Ford F-150 have?

In 1979, the Ford F-150 did not have a single engine option. Buyers could choose from several powerplants, ranging from a durable inline-six to a family of V8s. The core answer is that the 1979 F-150 could come with a 4.9 L inline-six or one of several V8s, including the 302, 351W, 360, and 400 cubic-inch designs.

This article explores the engine lineup for the 1979 F-150, how those choices affected performance and practicality, and why the exact engine depended on trim level and market. We’ll also cover how to identify the engine in a specific truck from that year.

Engine lineup for the 1979 F-150

Below is a concise list of the engines Ford offered for 1979 F-150 models. These are typical configurations, though availability varied by trim level and market.

• 4.9 L I6 (300 cu in) — inline-six known for reliability and decent torque at lower RPMs


• 5.0 L V8 Windsor (302 cu in) — classic small-block V8 common across many Ford trucks


• 5.8 L V8 Windsor (351 cu in) — a popular larger-displacement option


• 5.9 L V8 (360 cu in) — robust mid-size V8 used in a variety of Ford trucks


• 6.6 L V8 (400 cu in) — a larger V8 for heavier-duty duty and higher torque

Engine choice shaped performance, towing capability, and fuel economy, and which options were actually available depended on the truck’s trim, market, and production date within the 1979 model year.

Identifying and understanding these engines

To confirm the exact engine in a specific 1979 F-150, check the factory data plate, the build sheet, and the engine stamping on the block. The VIN and accompanying documentation can reveal which engine was installed when the truck rolled off the assembly line. If you’re restoring or purchasing a vintage F-150 from 1979, verifying the engine through official records helps ensure correct parts compatibility and performance expectations.

Quick identification tips

Look for the engine code stamped on the engine block and cross-reference with Ford's data for that year. The valve cover and intake manifold often bear distinguishing markings that indicate whether the engine is a Windsor or another family member, such as the 300 I6 or 360/400 V8s.

Maintenance considerations for 1979 engines

Because these engines come from a period with different emissions controls and carburetion standards, carburetor tuning, ignition timing, and vacuum/PCV systems are key maintenance areas. If you’re keeping a 1979 F-150 roadworthy, prioritize a good carburetor rebuild (if applicable), proper ignition components, and verifying the cooling and fuel systems for age-related wear.

Summary

The 1979 Ford F-150 offered a range of engine choices rather than a single option: a 4.9 L inline-six and several V8s, including 302 cu in, 351W, 360, and 400 cu in. Exact availability depended on trim and market, so the best way to know which engine a particular truck has is to check the original build data or VIN-related documentation. This variety reflects Ford’s approach to tailoring F-150 powertrains to different use cases—from everyday driving to heavier-duty work.

Is a Ford 302 a good engine?

Yes, the Ford 302 is a good and versatile engine, known for its dependability, strong performance for its size, and extensive aftermarket support. It's a popular choice for both daily drivers and performance builds due to its relatively simple design, which makes it easy to work on and modify for more power. 
Strengths of the Ford 302 engine

• Reliability: The 302 has a reputation for being a durable workhorse, with many examples lasting for hundreds of thousands of miles. 
• Performance: It offers a great blend of low-end torque and high-RPM power, providing good acceleration without the weight of a larger engine. 
• Modularity: Its simple design and a massive aftermarket parts selection make it easy to upgrade. You can build a mild street engine or a high-horsepower monster with many different modifications. 
• Versatility: The 302 was used in a wide range of vehicles, from cars to trucks, making it a common engine in many classic and modern vehicles. 

Things to consider

• Power output varies by year: The engine's power output changed significantly over the years due to different emissions standards and fuel injection systems, so a later fuel-injected model will perform differently than an earlier carburetor version. 
• A larger 351 Windsor might be better for some applications: While the 302 is excellent, the 351 Windsor has a larger displacement and can provide even more torque and power potential with fewer modifications. 

Is it right for you?
The Ford 302 is an excellent choice if you want a reliable V8 engine that is easy to work on, has a huge amount of available performance parts, and can be customized to fit a wide range of applications. If your primary goal is to build a high-horsepower engine and you have the space for a physically larger engine, a 351 might be a slightly better option.
