CarGurus' 1980 Ford F-150 Review

1980 saw the redesign of Ford's flagship F-series trucks, with a newly angular profile. The 1980 Ford F-150 once again offered buyers the choice of a Windsor V-8 engine, along with the Cleveland V8 and a 300-cubic-inch straight-6. Aside from that, buyers found little change underneath the square-shouldered new body; the 80 Ford F150 pickup delivered the same rugged reliability as in past years.

The 1980 Ford F150 shipped off the line in several trims (Sport, Ranger, Ranger XLT, Lariat, and Custom), with a range of cab, bed, and tonneau options ideal for farm, ranch, and other workhorse uses. (The supercab extended crewcab was available only in styleside models, but fleetside choices included both 2-door and 4-door cabs.)

Tough enough to go off-road, the 80 Ford F-150 offers plenty of power and muscle to today's tuners and project enthusiasts. Its solid and durable nature, along with its affordable price, adds up to a strong fanbase for the 1980 Ford 150 even today.

*300 ENGINE:

A big 300 CID (4.9 L) six was added for the F-series in 1965 and were essentially a 240 CID (3.9 L) with a longer stroke (the two are nearly interchangeable aside from a few parts). It produced 170 hp (127 kW). The 300 became the base F-series engine in 1978 at 114 hp (85 kW) (hp number changes due to Ford switching to Net power ratings in 1971.) Power outputs were increased to roughly 122 hp (91 kW) during the early 1980s before fuel injection was introduced. This became the primary engine of the line, eclipsing the 240. Unlike the Falcon engine, it featured a separate intake manifold which could be easily replaced with aftermarket manifolds offering the promise of even more power, through the installation of larger carburetors.

Also during the late sixties and early seventies, the 300 was used in larger vehicles such as dump trucks, many weighing into the 15,000–20,000 pound (7,000–9,000 kg) range. These 300s were equipped with a higher flow HD (Heavy Duty) exhaust manifold since the engines were going to be constantly working in the 3000–4000 rpm range. These rare, yet effective, manifolds had higher flow than the electronic fuel injection 4.9 (300) manifolds and some headers.

This engine is also used by Stewart and Stevenson in the MA Baggage Tow Tractor (pdf), as well as a multitude of other pieces of equipment, such as ski lifts, power generators, wood chippers, tractors, and, until they converted to diesel engines, most UPS trucks. Many UPS trucks still use the 300 to this day.

In stationary service (generators and pumps) fueled with LPG or natural gas, this engine is known as the CSG-649.
