Common Ford 390 FE Engine Considerations

While the 390 FE is a robust engine, like all older internal combustion engines, it has its known characteristics and potential weak points that experienced mechanics and enthusiasts are aware of. Remanufacturing processes aim to address these, but understanding them can help you appreciate the quality of a well-built unit.

Cooling System Efficiency:

The FE series engines, including the 390, can sometimes be prone to overheating if the cooling system isn't in optimal condition. This is often due to the design and the age of the vehicles they were originally installed in. A remanufactured engine should come with cylinder heads that have been properly machined to ensure good sealing, and a reliable water pump is essential.
