Depends on what you men by strong Coastguard (Thank You for your service!) ... It's rated at 170 hp and a long run as the primary power plant of the truck line indicating it's reliability, strength of design and reputation. That is echoed by the fact that it is the engine of choice with most manufacturers of ground transport and support vehicles you see servicing the airline industry at the airport. Good luck

Yes the 300 is a very strong motor, i have heard story's of people having up to 500,000KM on a 300 and it still runs great, i personally have 237,000 on my 4.9 and it runs like a charm, doesnt burn any oil or skip a beat. Id swear it was new

The 4.9l, otherwise known as the Inline 6 or 300 6 is a very reliable motor. You keep thick oil in it and it'll run forever. I've got a 67 F100 with the inline six and I will admit, I do burn around in it every now and again. But not alot. As long as you give it an oil change and don't put it above 3,000 RPM's, it'll run forever. Mine has 200,000 miles on it so far.

Those Ford inline 6 (300) were one of the best engines built by ford, they go for ever with minimum to now trouble as long as you change the oil when supposed to. I had one (1981) that went 500,000kms and never smoked before the frame rotted and sold it for parts, two other people I know had one they had real good luck with.

My 92 f150 has the 300 in it and I have pulled anything and everything I've needed it to and the fact that it does need to be rebuilt it pulls like no tomorrow.

I've had a F150 (Northland Edition) since it was new in 1991 with a 4.9L I6 and I have NEVER had an engine problem with it! Brakes, Tires, Oil and filters are the maintenance items needed. It has 460 thousand miles on it and it still purrs like a kitten. These days I mostly use it to push snow off my driveway and yard. This truck and my Jeep GC (Laredo) have been the most reliable vehicles I have ever owned. I wish I could say that for the myriad cars I've owned.

it is a torque engine, not a speed/horsepower engine. It's VERY STRONG in pulling trailers,etc, but not so "strong" if you're going 60 mph and want to hit the gas to go 70 mph.

Holy crap....years have gone by and the joys of the straight 6 have gone by and few can appreciate how great these engines are! Bottom line - enjoy your 300 & revel in the hp and mileage you get!!!!; I'm reveling in the V8 joys of the 57 Chevy. One of my best friends has a 91 F150....what an awesome truck!!!!!

In terms of toughness, the 300l is the baddest engine on the planet. Keep the oil changed and never let it overheat and it'll outlive YOU.

This past Thanksgiving, I purchased a 94 Ford F150 with a 300 L6 inline 6 cylinder engine and a 5 speed manual transmission. The truck had sat for 8 years after the owner had a stroke and passed away. His widow sold it to me for $650. After replacing the battery, fuel tanks, fuel pumps, sending units, belts, hoses, and tires, cleaning the injectors and lines, and tuning the engine, I turned it over and with the help of some starting fluid, crankedit up. It runs like a dream. I have put almost 4000 miles on it since then. I change the oil and filter every 3000 miles.
