From 1964 through 1996, the 240 cubic inch, (3.9L) and 300 cubic inch (4.9L) Sixes are well-known for their durability. Simple design and rugged construction continue to make these engines a favorite to a number of Ford enthusiasts to this day. Many have seen 150,000 to 300,000 miles without anymore more than minor repairs and engine oil changes. Due to the continuing popularity and abundance of vehicles that used this little powerhouse, it is one of the most popular rebuilt engines we sell.
One example of the engine’s sturdy design is the fact that no timing chain or timing belt (both of which can break, causing frustrating downtime and a need for a rebuilt engine) is used. This particular generation of Ford Six cylinder engines was designed with long-wearing gears for that purpose instead. Few modern engines use timing gears nowadays, timing belts are by far more common, especially among foreign automakers.
Both the 240 and the 300, no matter the application, used a single barrel Carter carburetor until the introduction of Electronic Fuel Injection. With proper gearing, many F-trucks and Broncos are able to achieve over 20mpg with these carburetors when properly tuned.
The fuel economy of the 300 makes the engine a popular choice amongst truck enthusiasts that want both power and economy. Combined with ultimate durability this engine sustained few modifications over the years. In this case, if it ain’t broke, don’t fix it. Even performance enthusiasts make wide use of this engine primarily because of it’s affordable cost, response to performance upgrades and brutal durability.
What is refreshing about a rebuilt engine of this nature is that it needs few if any upgrades. It is one of the few cases of an engine that was designed well, and with the use of professional grade rebuild parts produces one of the most reliable engines ever.
