is the 300 6 the best motor ever made

 

from experience with them i would say yes. very reliable. carb models run more efficent then the efi models though. my dad sold his truck with 210,000 miles on the 300I6. eng is still running.

 

It sure ranks right up there.

 

Best made for what?

You ask a question, that has too many possible answers.

Are they reliable, yes as much as any motor. They have their problems.

Do they get good milage, not any better than a small V-8.


My preference for favorite six, would a Jeep 4.0l. Smaller,lighter, better mileage, good power numbers for a straight six, outstanding reliabilty. Compared to the Ford 300.

 

Right on!!


I'll never get it..............they lasted a long time; who cares? Most people don't keep there stuff that long.


They're underpowered (carbed or EFI) the low RPM torque is OK for a 300 CID engine, Sorry, I drive/pull faster long after that whopping 300 feet pounds is gone.

The last few years of their existence, Ford couldn't give 'em away.

PB or Jeff will remember this; You could get a FULLY LOADED Eddie Bauer I6 with a 5 speed for around 11K.........Cheaper than a Ranger!!!

No, not the best motor ever made.

One of the most durable? I'll buy that.

 

I'll not stand for too much bashing; let's define terms here. Better than an equivalent or smaller displacement V8? Yep. Especially if you are talking about a 305, 302, 289, a 4.6 or Dodge's 4.7, for example, or Ford's 4.2 V6, intended as a replacement. I've towed and hauled with all of them, and the 300 beats them. Motors downshifting on every little hill are annoying when you're hauling a load, and if they have no torque down low they rev to move a load. That's what the V's do, and it is not a good characteristic for a load hauler. My 4.2 V6 F150 couldn't climb even the slightest hill just holding speed while pulling a 4000 lb trailer without going into second. At 60 mph, that's too many revs, too often.

That's why the 300 has a reputation for durability; it does not rev. Low revving engines last longer.

I prefer the 4.9 Ford engine to the Jeep 4.0, especially for a 4000+ lb vehicle. Why? Same reason the 4.2 or 4.6 Ford is less suitable; far less low speed torque, which makes it inferior for hauling a load. The 4.0 liter isn't all that hot for mileage, either. My Jeep 4.0 would get a whopping 17 mpg while pulling a far lighter vehicle than my truck. If I didn't haul anything, and my vehicle was light the 4.0 would be fine. I'll also offer to hook bumpers to all of the above motors in a pulling contest. The 300 will win. It would be very difficult to prove that a 4.0 Jeep six is any more reliable than Ford's 300. I doubt it.

Criticisms? Sure, I've got some. As a carbed motor, it's a pig, and runs out of air too soon. The one barrel intake and single log exhaust choke the crap out of the motor. The EFI models introduced some problems of their own. All were below the motor's potential. I would prefer an EFI 300 to any of the motors listed above. My own towing/hauling six has headers, overbore (309 ci), compression bump, Offenhauser intake, and 390 Holley, with matched and polished ports. Low speed torque is retained. As a stock EFI, it is a better truck motor than all the small V's. With a very mild enhancement it is much better.

ONE OF the best motors made. Could have been better had Ford developed some equipment to get better performance out of it. Need more? Add your own. Ford's 4.2 V6 replacement was a step backwards.

 

So the Majority of us here believe!
Once one is through w/ some Mods, the 300 I-6 becomes More than just an Extremely Durable Engine & becomes an Over-All Performer.
On average one can Double the FPT & HP.

 

Hmmm, my vote would have to go to the ol' Mopar Slant Six.
300's a darn good engine for sure though.

 

Its better than stock V-8's in its cubic inch range. It will last longer than most stock V-8's in its cubic inch range. Its got more torque at lower rpms than stock v-8's in its cubic inch range, which is what you want in a truck. I'd rather have all my torque at 2000 rpms than at 4000 rpms. I'd take a 300 over a 302 or a 4.6l. I dont wanna rev to 4000 to get any torque. As for the best motor ever made, thats an opinion. There is no best motor ever made.

jeep 4.0's have 181 h.p. @ 4600 RPM & 222 ft. lbs. @ 2800 RPM. no *****. The 4.2 beats that thing. I remember when i hooked chains to a wrangler with one and drug it with ease. better mileage? no, if they do barely. good numbers for a I6-mildly, reliability-i dont know, but my I6 has 166k on it and the motors never had a problem. The 300 outlasting the body of the truck it's in says something about reliability.

 

Its the best towing engine there is. The FE 330HD comes close though.

I'm starting to lose count of the 370/429/460 to 300 swaps I've done on F350's and F600's.

 

I've seen way too many oil pickups in 225's move and hit the crank to even touch one anymore. the oil filter actually screws onto the oil pickup. It make a noise very simular to the regular valve train noise untill the crank wears a hole in it.

I've also seen a lot of #5 rods go bad on 225's. They come through the block and actually rip the starter off the transmission.

 

Umm, no it doesn't, it screws onto the oil pump, which bolts to the right side of the block above the oil pan. The oil pickup screws into the bottom of the block below the oil pump.
As for the other, darn near any engine can have problems with the pickup if the knucklehead that puts it in doesn't know what he's doing.
The cars attached to these motors usually fall apart before the motors finally go. My dad's Valiant was almost at 500K before I, being a new driver , took it out and spun a rod bearing. I replaced the motor and now, about 17 years later it's still running strong. And there is testament upon testament about the leaning tower of power; it will always be the best gasser in my book.

 

trust me, one really tight filter that takes alot of effort to remove will swing that pickup into the crank, or closer to the crank. a couple times and it starts ticking

 

Nope, are you going to make me take my digital out to the garage?

 

where is the cam position sensor on a ford stright 6 efi. i have a 96 f150 with the stright 6 and its going. keeps throwing me the p0320 code. and i have narrowed it down to the cam positioning sensor however i cant find it!
