Keeping up with routine maintenance, like replacing your air cleaner routinely, can help your Mustang's engine perform well for years. If yours is still running well, then a little basic maintenance may be all you need.

If you'd like to improve your performance, then adding an upgraded carburetor, converting to fuel injection, or adding a supercharger could give you the boost you're interested in. Even simple fixes, like an underdrive pulley set, can add valuable horsepower to your Mustang.

Crate engines are a perfect option for those whose engines aren't even coming close to meeting their needs any longer. Whether your engine is struggling with serious mechanical issues or you just want a significant horsepower boost, sometimes replacing an engine is the right decision. If you'd prefer to custom build your engine, then you can start with a cylinder block and build an engine that's perfectly suited to you.

With the right engine, your Mustang can perform even better than new.
