I have an 95 F-150 it has 260,000 miles on it and I think it's getting tired. It seems to be having a problem pulling my 16' open trailer. The trailer is a 20 year old hand made heavy trailer. My question is, I need to replace the engine. Should I put another 302 in the truck, or convert to 351 or possibly a diesel. I do not want to get rid of the truck, it is in good shape. I will be using it solely for mowing trailer, posibly some light materials. (Mulch, dirt, ect...) I want the truck to pull this trailer without alot of strain on the engine/trans. I know there will be a degree of strain on any eingine. Any suggestions on what I should do.

If you are looking for more power from whatever you replace it with, you might want to consider a 347 kit. There are alot of companies that offer them and since they are just a bored and stroked 302, fit will be easier and there will be less parts to buy.

I have never cared for the 302 in a pickup. How about a 300 6? Good power and torque for pulling. They are durable as well.

I have a '94 Ford F-150 5.0 with 268,000 miles for sale right now. Same thing, it is getting tired. I replaced it and one of the reason for for it was that I only get about 80-100K on a tranny and I already had about 60K on the most recent one. I knew that pulling as much as I am now I would be replacing it soon and I just did not want to put any more money into that truck. The trannys in those trucks just are not made for the heavy hauling that most of us do on a regular basis. Ocassional towing they do great, but they wear down quick when used for that towing everyday.

It may be easier to just swap in the replacement 302. It did the job for 260,000 miles and the truck is already set up for it (computer, etc.).

A direct swap would be the easiest and then you wouldn't have to modify the wiring harness or be required to get a new computer. I would replace the engine and then start looking into a 2nd truck and keep that as a back-up. The engine has 260k on it, I doubt that just the engine is tired, all the other parts are tired and pulling everyday is not easy on a truck. Your best bet might be to look for a diesel or a truck with a big block v-8 or v-10. Those trucks are built for hard work and towing so when it wears, it wont wear as quickly or as much.

I agree with alot of you, when you say replacing the 302 will be the easiest route. But I want to know if it would be worth replacing the engine, or spend a couple extra bucks on a bigger engine.

LindblomRJ- Do you have experience using a truck with the strait 6 300. I know it is a great motor, but would it be good pulling a trailer everyday. At least compared to a 351 or a 460 or 7.3 deisel.

Yeah I have a 79 150 with a 300. Spent most of its life on the ranch. Its not going to be a 7.3 or a 460. Its power band runs about 1000 RPMs to 2000 RPMs.

These engines were used a lot in the early 70 in school buses and dump trucks. Medium duty trucks.

For LCOs with couple of ZTRs and tools should not be a problem. I have pulled a scraper (hooks up behind a farm tractor) no problem. Have hauled my H Farmall with out any trouble.

How do you think it would compare to a 302 or 351 for pulling a 16 foot trailer. Lets just say 7000 pounds.

The 300 is far better than the 302. I think they would be a better option than the 351. (I don't have any expirence with the 351.) The old 360s were doggy though.

I may have too look a litle cloer at this option. What ideas do you have about a trans.

I think the one in my 79 is NP405 (I think) 4 speed. C6 or a good 5 speed. I would steer clear of the mazda made trannys

A good site would be fordsix.com There is quite of bit of knowledge there.

I will check it out, I need to do something. I just feel like this thing is going to poop out.

Get a 3/4-ton, or 1-ton truck. Forget about the bigger engine idea...truck is too old and unless you have a whole donor truck and a whole lot of spare time, you're asking for pain.

Totally forget about diesel....there are no diesel 1/2 ton Fords...the diesel is too heavy for the front suspension. You will go around squatting and wearing out front tires.

Even better, get an Isuzu or Fuso cabover. Once you do, you'll never go back to truck and trailer.

I have an 88 F-150 that has the 300 Straight 6 in it. It is a great pulling engine. Plenty of torque! I think I like it about as much as the 351 that is in my F250. It does a lot better on fuel than the 351 will ever do!

I know you've made up your mind on replacement.

My advice to you is, sell the truck, and get one with lower mileage.

You'll save time, aggravation and the time saved you can better put to use working the jobs.
