1971 Mustang Engine

If you’re building a race, drag, or show car, or you simply want a high-performance Mustang that you can enjoy, a crate engine or custom build from the block up is going to be at the heart of your project.

We offer engine parts and full builds for each skill level. If you're a beginner and just need a drop-in replacement that you can customize later, a crate engine is the perfect choice. For advanced mechanics, our cylinder blocks provide the freedom that comes with building a custom engine from the ground up. If you're satisfied with your engine as it is, some performance upgrades or replacement parts will give you an edge and keep your pony ahead of the game in preventive maintenance and prolonged engine life.

Not the year you are looking for? Check out these years: 1964, 1965, 1966, 1967, 1968, 1969, 1970, 1972, or 1973 for additional options.
