At first sorry for my bad English, but I´m a german Ford-F250 Driver

I have a question, I own a Ford-F250 built in 1984 with an 300 cui engine, how much hp has this engine? In the german carpaper (?) is 118 kw noticed. Could that be? That would be 160 (German PS).

It would be nice if someone could help me to understand this theme.

Thx in forward!

Welcome to the forum, borni! We welcome members from "across the pond".

Someone will respond with the "exact" "published" horsepower, but if your 1986 is like the one I have, it is approximately 120 horsepower. Originally [circa 1965], the 300 engine was rated @ approximately 170 hp, but this is what we refer to as "gross" horsepower. Sometime around 1972, we in America, switched to "net" horsepower and the conversion made the figures drop. In 1987, the engine was changed from carburetion to fuel injection and the horsepower went up to 145.

Is your engine still original? That could make a lot of difference, if modifications have been made.

This engine is known as being very reliable and easily maintained. It is more like a tractor engine rather than a race car engine. It develops respectable torque at very low speed. Maximum torque is @ approximately 1600-1800 RPMs.

 

Thank you for your answer.

I think the engine is normal. It looks so. It´s an 1984 modell/engine.
I thing the 160 PS is an mistake in den paper, because the 118 KW(kilowatt) are the 118 PS (horsepower).

But it is no problem for me, the engine runs very good (toi,toi,toi )

"That could make a lot of difference, if modifications have been made" ==> which easy modification could I make by myself?

Have a good day or night

The 1984 engine [as originally equipped here in the U.S.] will have the "feedback" carburetor. This was what was offered just prior to the advent of fuel injection [1984-1986 for non-California trucks]. The carburetor is controlled by a computer which monitors temperatures, Oxygen content in the exhaust stream as well as intake manifold pressure. If any of this is tampered with, the computer makes the carburetor go into the rich mode and locks the distributor timing at 10 degrees BTDC. So the first question is to determine if your vehicle is still original?

In my family, we have a 1984 as well as a 1986, both with the 300 [4.9L] engine. Using the search feature at the top of the page, you can find many threads of how to make the 300/4.9L more powerful and read for hours. I tend to be of the opinion that one should embrace this engine for what it is, as long as it is still mechanically in good condition, as drive it. You did say, "the engine runs very good (toi, toi, toi )"

As with any engine, for best overall performance, check all components to make sure they are within factory recommended specifications.

Check the ignition components [i.e. distributor cap and rotor, spark plugs and spark plug wires and ignition timing [read about spout wire].

Also, check air filter element, PCV valve, vacuum hoses [for leakage].

Is the thermostat working and is it the correct temperature?

The following items are geared more to help reduce fuel consumption:

Make sure the tire air pressure is correct, the tire alignment is correct and that the brakes are not dragging. Is the truck loaded with unnecessary weight [extra items]?

Keep in mind that these trucks have the air flow characteristics of a "brick" and if driven above 100 kph the drag increases exponentially.

By the way, I love these trucks, but am a realist and accept them for what they are.

Performance cost money... how deep are your pockets?

 

These engines were never rated very high for horsepower. They make lots of torque, down low. Even the 120HP models make over 250Lb/Ft of torque, in the 1400-2200 RPM range.
They will move a lot of weight, just not quickly. Very much like the inline 6 diesel engines used in large trucks.
These things can even last 200-300K miles, given proper servicing. Sometimes reaching 500K miles before needing refreshed.

They can be reworked to make plenty more HP, but the torque output is the number that really matters.

 

Good Morning,

thank you for the detailed answers.

At first I will say that I´m very satiesfied with the car and the engine too, how it works at the moment.

I was only wondering of the numbers written in the official "german"-Paper. But that is not so important for me.

I like driving with 90 km/h on the highway (schould be 55.9234 miles/h ) because it so relaxing.

So, today I have to work only a few hours and then we will drive to this US-Car Meeting in Germeny (Oldenburg): Big Bumper Meet Oldenburg e.V.

Thank you!

Hello Borni!!! Welcome to FTE! Awesome truck!

The 300 is an industrial strength inline six and has a 4'' bore and 3.98'' stroke. It makes 145 horse and 265 ft lbs at 2,000 RPM. The carb'd versions make their peak torque around 1,500 RPM.

The 300 was used in UPS trucks, school busses and farm equipment, as well as log splitters and generators.


The 300 has 7 main bearings. The average V8 only has 5.

 

I'm guessing that 118 KW is a gross measurement. No exhaust system, no belt-driven accessories, no air cleaner, measured at the crankshaft. 118 killowatts = 160 Pferdestärke = 158 (imperial) horsepower.

If the 1984 makes 120 net HP then that that would convert to 121 PS or 90 KW.
