When Ford Accidentally Built an UNKILLABLE Farm Truck

Before modern trucks were filled with cheap plastic and computers, Ford accidentally dropped an unkillable industrial workhorse into their consumer trucks. The Ford 300 Inline-6 (4.9L) is widely considered the most reliable American engine ever built. Originally designed to power heavy equipment like woodchippers and UPS trucks, this massive cast-iron, gear-driven straight-six found its way into the legendary F-150, F-250, and Broncos. With seven main bearings and a timing gear setup instead of a weak chain, it was built like a tractor. From humiliating the Chevy 292 to easily hitting 300,000+ miles without a rebuild, here is the true story of how Ford built the ultimate bulletproof farm truck. 👇 What was your experience with the legendary 300 I6?
