I was looking at buying a truck i was told it had a 8cyl but it really had a 6cyl. Its a nice truck and im still considering it. Its a 4.9 liter inline 6 (called the big 6) and they said it has equal pulling power to a 302 because its manual and you can gear down. Is any of this crap true? thanks for the help<br>Dingo

My friend just sold his FWD (made by international I believe) and think it had the same engine. It was a big snow truck and the engine had plenty of power. Also, he said they were simple and easy to work on.

Dingo,<p>It's a 300 ci six. Ford offered it only in trucks/vans. I have an 83, that year it had MORE torque than 302, 302 had more hp. It has a lot of power down low. Great for pulling weight or plowing. It is NOT as quick as 302, if you want a race truck, buy the 302. For what I do the 300 is great...<p>Dave

So you think it would be a good truck to pull a lawn trailer full of equipment or a trailer full of mulch. Thanks for the help guys<br>Dingo

Dingo,<p>I have pulled a 1 ton chevy on a car trailer. Probably close to 7K lbs. It was working hard to do it. I also use the truck to haul motorcycles to the track. Usually two in the back(1000lbs), plus small trailer. Handles this NO PROB. The six is one of the most reliable engines Ford made. It has NO timing chain, it's gear driven...<p>Dave

The 300 is one of Ford's most durable motors. It builds great torque due to to it's long stroke. I had a 84 F-250 with a 4 speed and 300. It would easily pull two full anhydrous ammonia tanks which weighed approximately 20,000 lbs full. Besides anhydrous tanks, we'd pull a 30 ft Donahue trailer loaded with drills(used for seeding crops), self propelled swathers, also pull large 800 bushel grain dryer. You name it, it would pull it. Also had a 89 F150 with a 302 and a 4 speed. It wouldn't pull nearly what the 300 six would pull. I wouldn't hesitate to buy another 300 for a work truck. Plus that pickup had 160,000 miles on it when I sold it , motor was untouched and still ran strong, although rings or guides were starting to wear as it was using oil, but all in all a great motor.

I agree with the others, the 300 6 is a great engine. I've had a few and wouldn't hesitate to get another one and use if for pulling a trailer.<p>----------<br>&lt;a href=&quot;http://www.townserver.com/elm/&quot;&gt;Eric@ELM&lt;/a&gt;<br>

I'd walk right past a 351,and 302 to buy a 300 inline 6.You scored with this truck-go buy it before someone else does.You wont win any races,but it is well suited to pulling a trailer.A few had wrist pin/piston slap,if not they'll run a long time,you will save money on fuel too.Also what year is it?EFI or carb?I love the EFI 300,bottomless torque from idle up.<p>----------<br>John D<br>

what year did these babies come out, it sounds like just what i'm looking for, what kind of gas mileage do they get

I just bought a 1985 f150 with the 4.9l engine it has 120k miles on it and runs better than my 1989 5.0 f250. I also noticed because of the gear ratio that it has more power than my 5.0. The body is in good condtion and interior is good only need to add an FM sterio. I plan to use this as a back up for pulling my trailer and doing small landscape jobs. I plan to get it repainted back to its original color , midnight blue, anyone have any links to parts manufactureres incase I want to restore or possibly turn into a street rod. Thanks in advance really excited about this used truck that runs soo great.

I have a 96 F150 with the 6 cyl. auto, only used to pull the mowing trailer, plenty of power, good on gas and dual tanks. Only thing i've done to it so far is brakes, great truck

I borrowed my friends 85' 6 cylinder with a manual trans. It was very impressive. It also had 145,000 miles on the thing. He keeps it around as a back-up truck.

I have a 81 ford,it has the 300 straight 6.We a going to junk the truck in a few monthes,not becouse the engine is toast,but becouse the body is shot.That engine is awsome!We ran it for 3 years,hauling aprox. 1 1/2 to 2 tons each week.That engine will never die!!!!!We treat the thing like crap and it just laughs in your face!!!!!!!We just picked up a 89 f-150 with a fuel ingected 302.I hope the engine will work out all right.When I can get the funds,I would like a fuel injected 300,that would be great!I think the 300 is one of the best designed and built engines detroit ever spit out!And as far a how long the 300 has been around......I know a guy with a 50's ford truck with one in it.So it has been around for quite awhile!

I've got everyone beat on this one. One of our trucks has a Ford 'big 6' in it with--get this-- 320,000 miles. We use this one everyday still. It is a great engine to say the least. Plenty of power for pulling 12' trailers and decent gas mileage (around 15). Change the oil every 3000, and it should run forever. It is a '92 w/ a 5 speed by the way. Couldn't be happier with it.

My first new truck was a F150 with a 300 inline with a three on the tree. Should have never traded it in. Great gas mileage, never used oil, and plenty of low end power. Wish I still had it.

I use to work for a bread company when I was in college loading trucks at night. The trucks were all early 60's models. All had Ford 300 inline 6's. Use to pull the charts in amazement that several had over 3,000,000 miles and had only been rebuilt a have dozen times or so. Mechanic once told me it was under $100 to rebuild one. I have seen rebuild kits today for about $134.00. Very economical motor.
