I have a 77 250 with the I6 and 3 speed with hurst shifter lol. This is one tough hauling, towing truck.. It out tows our practicaly new 89 e250 with the 302 and aod. " van has like 65k and is in show room condition" The only down fall is the 3 speed. It needs a gear between second and third.. Personaly i would rather have the 300 6 in my ranger than a 302. I towed a 2000 gmc 3500 4x4 on my car trailer with my ranger yesterday... I was wishing i had that 300 6 instead of my 3.0... Got home hooked the trailer to my 250 to move it around the soft muddy gravel driveway and that 300 didn't even begin to notice that trk or the 1300 lb trailer it was on..
The straight 6 300 was designed to be a work horse..... From Wikipeda...
Produced at the Cleveland Engine plant in Brook Park, Ohio from 1964 through 1996, the 240 and 300 Sixes are well-known for their durability. Simple design and rugged construction continue to endear these engines to a number of Ford enthusiasts to this day. Many have run 300,000 to 600,000 miles (480,000 to 970,000 km) without any more service than standard oil changes. The engine has earned the terms "bullet proof" and "indestructible" by many. There are numerous claims of those who have purposely sought out to destroy one through abusive use, and were unsuccessful in doing so.
One example of the engine's sturdy design is the fact that no timing chain or timing belt (both of which can break, causing unwanted downtime or even engine damage) is used. This generation of Ford Six was designed with long-wearing gears for that purpose instead. Few, if any, modern engines use timing gears; belts are by far more common, especially among non-domestic automakers.
300
The 300 cu in (4.9 L) six was added for the F-series in 1965. It was essentially a 240 cu in (3.9 L) with a longer stroke. The two engines are nearly identical; the differences are in block dimensions, combustion chamber size, and the rotating assembly. It produced 170 hp (127 kW) (gross). 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 separate intake and exhaust manifolds, which could be easily replaced with aftermarket manifolds offering the promise of even more power, through the installation of larger carburetors and a higher flowing exhaust system.
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.
Engine sizes were converted to metric for 1983, causing the 300 to become the "4.9". Fuel injection and other changes in 1987 pushed output up to 150 hp (112 kW) with 8.8:1 compression. This engine was gradually phased out, ending production in 1996, and was replaced by the Essex V6 in the F-series trucks with their 1997 redesign. However, it was renowned for its durability, low end torque, and ease of service. The 300 4.9 came with the Ford C6 and E4OD transmissions, as well as the Mazda built M5OD 5 speed manual transmission. The 4.9 liter 6 cylinder was built in the Cleveland, Ohio engine plant.
This engine is also used by Stewart and Stevenson in the MA Baggage Tow Tractor (pdf), and Harlan in their standard tow tractors [1], 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.
[edit] The Ford Inline six in racing
The Ford Inline six has had a small though colorful career in racing, which has increased in recent years due to the rising popularity of the motor and the availability of performance parts.
A recent yet giant step in Ford Inline six racing has been performed by McLearran Motorsports in Tucson AZ. The McLearrans, Wil and Kelly, have achieved enough notice that their 1963 Ford Falcon has been seen in several magazines and was scheduled to make an appearance on the show Pinks.
The 1963 Falcon driven by McLearran Motorsports' Kelly McLearran has been dyno tested at 323 rwhp @ 4500 rpm and 502 rwtq @ 2650 rpm. The car has run a best time of 10.89 seconds at 1/4 mile, with Kelly driving.
