What is the Ford 300 inline six?
Quick Answer
The Ford 300 (4.9 liter) inline six is a 300 cubic inch engine that powered Ford trucks, including many F-250s, for decades. It is famous for low-end torque and durability, a workhorse that often runs past 300,000 miles. It is the cheapest classic F-Series engine to keep on the road.
The 300 six is the truck engine enthusiasts trust.
Why it is loved
Simple, torquey, and nearly indestructible, it was built for work and routinely outlasts everything around it. Not fast, but dependable.
Buyer's note
A 300-six F-250 is the value pick for a usable classic truck. If you tow heavy, the 360, 390, or 460 V8s do more, but they cost more to feed.
