I FORGOT CUMMINS, HERE ARE THE RANKINGS:
Cummins 5.9 - S tier: Indestructible engine with heaps of torque, absolute masterpiece.
Cummins 6.7 - High A tier: Pretty much the same reasoning, but the introduction of the same emissions systems as the Duramax can create issues (not common), and be of general annoyance.
Apologies, that was a silly mistake on my end, thank you all for letting me know and I hope you enjoyed the rest of the video!
Man. You’re opening a hole into the diesel world. Cat 3126/C7. C13 3406 series C15/16 Cummins KTA/Big Cam n14 ISX12 ISX15, X15 Detroit 6-71, DD13-DD15. Volvo D12-D13 d16 Maxxforce 13-15 Mack. (Modern Mack Motors are Volvo starting back in 06 )
You forgot to talk about the torino version of the tornado engine 😥
@@curtisnoble. Not to mention the I6 diesels built by International (the DT-466, for example), Buda (used in lots of Allis-Chalmers equipment), John Deere, Volvo, Daimler/Mercedes/Benz, etc. And gasoline I6 engines--Continental, Cummins (yes, they made gasoline I6 engines), Daimler/Mercedes/Benz, BMW, etc.
For real gonna say gotta drive the 4.9 to get it to get it, honestly only showed up to see it. 😂
@@rockymountainjazzfan1822 well I didn’t want to go that far back in time.
Those ford 4.9L are absolutely insane with their reliability I’m glad to see it in the A tier but I feel it deserves to be S-tier.
So did those Cash for Clunkers junkyards. 300s ended not with liquid glass in space of oil but when they drill hole in the block.
powered a lot of UPS trucks had that sound one will never forget
No offense but Personally I think the 4.9 is way over rated, "TQ monster" nope just a buzzing lazy half dozen, reliability is about it's only shining attribute it has, the power to CI ratio is awful, the 302 Windsor is a way better engine there just as reliable and will eat the 4.9 for breakfast it will out tow and out accelerate a 4.9 at comparable fuel economy being only 3 ci larger? What does that say? It's not an efficient platform. I've had several of both and the 4.9 is a gutless wonder, yeah its reliable but so are many engines from the era that produce considerably more power so why bother...
Personally I hate the old school inline 6 engines, I've always wondered why when they designed the old school ford GM ect inline 6 engines they took all there knowledge of how to make good power and tossed it out the window. Firstly not using a cross flow head.. why? just cram the intake and exhaust manifold together so you get a nice hot intake charge so it has to have very low compression and no timing to avoid detonation. The big terrible flowing skinny log intake manifolds flowed terribly and the combustion chambers were terrible. They were gutless little tractor engines in a pickup, fanboys say it's a truck engine not a race engine, I'm not saying it is a race engine but if you just engineer it with efficiency in mind more power is a nice side effect, you get results that just don't leave power on the table for no good reason, efficiency is just less turning gas into heat and noise. ... Who doesn't want more free power? If GM or Ford built there I6 engines with basically a 6 slug version of their small block head they would have been soooo much better and it would have cost no more to build parts would be more readily available and would have been just as reliable but with a considerable power increase and likely better fuel economy, why would that be bad. As far a packaging an 8.2" deck Windsor V8 is tiny with a low deck height very narrow for a V8 and way shorter front to rear compared to an inline 6. I've seen Windsor and SBC v8s run forever with basic maintenance. Just my opinion. Anybody see the video of a ford 4.9 with a modified LS head or the video of the 4.9 with a modified Cleveland head? They both jam out, now they were both performance builds but it proves my point.
@@95Sn95 your comparing the HO. The 302 in the truck make the same HP and less torque at a higher RPM (the 300 makes 300 ft lbs at 800RPM).
The non-roller 302 is junk and had no business in any truck. The 300 beat the 302 in every way in this application, it was just offered for those buyers that "had to have a V8".
Show me a 302 that gets 22mpg and has over 500k miles and is all orginal. Both of those are common for a 300. You will be hard pressed to fin a 302 with over 200k before being rebuilt. My 300 is over 600k miles and still has over 150 psi on compression testing.
Chrysler's Slant Six is an absolute f***ing legend.
Ford's Barra 4.0L Straight Six is the engine that the US never got, but should have.
Yall didn't deserve the unmatched power of the mighty barra
Some guys are calling the atlas the ameribarra. Those are lesser known and grossly underrated. I believe they are every bit as capable, just dont have the aftermarket following… but some guys are working on it.
I wish the US got the Barra engines. Super reliable, capable, and torquey engines even though they were heavy as tanks
The Chrysler Australia 265 ci Hemi Six beat the 340 ci V8 in Aussie Chargers , best six ! Never sold in the US
@@Quxzy Still a Ford, which is originally an American Company
The old Hudson 308 flathead I6 definitely would belong in the S tier too, a flathead inline six that was dominating overhead valve V8s in NASCAR, definitely pretty cool.
I’m not a die hard Ford fan but I do think the 300 is one of the most bulletproof reliable engines ever built. You can still drive by some fields around where I live and see old 300s that have sat in the same spot for 30-40 years running irrigation pumps.
I worked for Argonne National Lab from 05-09. They had Chrysler 225s dating back to the mid 60s still running water and sewage pumps at the time. Most of the hour meters had flipped their 4 digits according to service records.
The 4.9 has to be S tier. That motor is arguably the most reliable motor of all time. It also hits peak torque dang near idle. Perfected over 100 years of development
I'm no Ford guy, but as a fleet tech for GoodYear for 9 yrs, I give credit where credit is due. The 4.9s with MPI were gas, oil and go and most of our E250 extended cargo vans hit 330k in constant city traffic with no trouble. When they switched to the 4.2 V6, we were lucky to get 150k before those mills had serious problems.
300. You must refer to it by cubic inch displacement, as God Himself intended 😂
The atlas I6 also comes in a I4 configuration, it also responds well to boost and has the nickname of the American Barra in some circles.
Don't forget the 5 cylinder version. I imagine it would be even better for turbocharging due to its odd cylinder count.
Wish there was more content on the vortec 4200
There is a little bit on youtubes. People are playing with them if you search it
@@frederickjeremy yea but most of it is from Nivlac57, we need more RUclipsrs to give this engine the recognition deserves
Same as a 6b Cummins 12v.
Find a 4 cylinder version in a old bread or Frito lay truck and some had a gm th-400 trans.
Holden red 6 actually came out in 190hp variants aswell, being a homologation version for production car racing back in the day and actually managed to out run the 351ci powered Falcon at Bathurst one year.
Uh...what did you miss?..how about the Hudson Hornet 308 six?..it was/is an absolute LEGEND!...Studebaker, and other independent manufacturer sixes should have been covered also. On another note, the Chevrolet 292 inline six should have been noted also...based on the Turbo-Thrift sixes, it has a unique taller block, and is absolutely indestructible...and talk about TORQUE! I own one, and it is my favorite engine, despite dismal fuel mileage. It is on par with the Ford 300 six ( I place it higher personally), only drawback is fuel economy, and the fact it only came in trucks and is fairly hard to find....
Not specifically mentioned was the 361 cubic inch GMC gasoline I6 that powered innumerable GM "deuce and a half" military trucks in World War II. Many thousands of those 361 I6 engines were sold as military surplus after WWII and wound up being used heavily in the civilian equipment market.
When the car is rusted out and considered unsafe to drive, the AMC I6 will be under the hood ready to go.
I can attest to that. I've had 3 vehicles with it & the engine was the only thing that didn't fail
@@zurn56 my hometown police department had one of those rare police special cherokees. It was slick. I still see it to this day. It lives a new life as a rural mail carrier.
'89 jeep Cherokee, no floor under the driver's seat, but that 4.0L was ready.
Nice, a channel that actually mentions the predecessor of the barra, nice work. Fun fact, the engine was called the falcon 6 until the 1990 single cam variant which was just called the SOHC. Then with the release of the AU falcon in 99, the name was changed alongside the engines final major update to the "Intech", which it stayed until the barra took its place in 03!
Keep up the videos, there a good watch imo
Glad you enjoyed the video, I appreciate that!
Proud owner of a barra here, amazing engine
That AMC I6 my goodness is that such a beast man, its frikken unstoppable
Drove a Grand Cherokee for years and I second this. Never had any internal issues with it even after 300k. I swear by it to my dying breath
@@tashaanlogan6990 the damn thing might outlive you, it's a running joke as being one of the engines likely to survive even to the heat death of the universe
Oh dude, no. The last generation Ford 300 is absolutely S Tier. You have to drive one to get it… they make peak torque at like 2200rpm. So they feel like a diesel without the cons of diesel.
If you look of the dyno sheet on stock one it’s hysterical, all peak torque at “around town” rpm and only like a 30hp increase as you rev it out to a whooping 4500rpm. There is almost nothing else like it…
At least A was pretty close, no doubt a great engine!
Chevy 292 is right there with it! In both durability, power, torque, and mod potential..sadly, they are not as well known, and produced in lower numbers(it was not marketed properly when it was in production)...
I had one in my truck with a 3-in straight pipe, guy with a Cummins went Blowing by me at a certain RPM and you couldn't tell his comments from my 6 cylinder Ford. Oh my God it was so sexy! But you're right torqued right out at 2200 RPM and Peak power at like 3500 RPM. Absolute monsters and pretty decent on fuel. Extremely obnoxious with a 3-in straight pipe though not going to lie
I see some of the homebrew turbo setups on here ,giving you a fat lump of like 425-450ft pounds.
Must hit like a diesel.
I would love to see a modernized 4.9, with a small turbo, and have it make a flat curve 450 ftlb at about 1800-3000rpm, mated to a heavy duty 6 speed manual transmission.
The 300/4.9 Ford absolutely needs to be in S tier. Bulletproof, good power and easy to modify and work on.
Good power? My neighbor's dad has an F150 with the 300 and it tops out at around 85 MPH. It does alright around town due to the decent low end torque and it is very reliable and easy to work on, but I wouldn't exactly call 145HP out of that large of an engine in such a heavy truck good power when the 302 makes 199HP out of almost the same displacement and seems to get about the same MPG.
I love my 4.9 to death but it’s gutless
@@averyalexander2303 I've owned both the 4.9 and the 5.0. I still have the 5.0 and love it, but I regret every day since I sold the 4.9.
Towing there is no comparison, the 4.9 will out-tow the 5.0 all day every day. Yes the 5.0 makes more power, but it has to rev very high to do it. With a 4 speed auto, that only gives you a couple good speeds you can maintain with the right RPM for peak power. The 4.9 is far less reliant on the transmission since it has a much flatter torque curve.
MPG is about the same, though I think the 5.0 is capable of better MPG empty. All things considered though, in a truck that's actually used for towing I'd much rather have the 300. 351W would be nice too but the MPG tradeoff isn't worth it to me.
@@supersnot4 Interesting, thanks for sharing! I don't have any experience with the 302 in a truck application, but I have a friend with a 351W powered Bronco and I realize that isn't a direct comparison, but to me, it feels quite a bit stronger than the 300 in the F150 despite the Bronco being heavier.
Both get bad gas mileage though. My friend's Bronco averages around 14-15 MPG with a very light foot and electric radiator fan conversion and he regularly sees 12-13 MPG or less if he hits any traffic.
They were dogs 101 hp in a F 150 those things couldnt do 60 and it took 32 seconds to hit 60 mph
Good Video, The AMC/JEEP 4.0 has never had forged internals or aluminum block or head. Have been working on these engine for over 15 years and have had ones making almost 400hp N/A. Excellent engines all around and as bulletproof as the ford 300 or chrysler slant!
Again,everybody forgetting the incredible Chevy 292...
Ive seen a couple of those 4.0’s go to just under 500,000 miles with nothing but routine maintence. I dont doubt they made it. I just left that shop before i got to see it.
@dyer2cycle I have heard awesome things about them just have 0 experience with them myself.
@@jamesfdeanjr7742The torque of a diesel is a good way to describe their off the line torque and lugging power...love them. despite having 8 fewer cubes than the Ford 300(smaller bore), the 292 actually has a longer stroke than the 300, 4.125" as apposed to 3.98" for the 300..if anything, stock to stock, the 292 will out lug a 300....
I've experienced both and they're both great engines, but the 4.0 is way more temperamental than the 300. Both will make stupid high miles but the 300 will make it with nothing but routine maintenance, whereas the 4.0 will have gone through at least one head rebuild by then at a minimum.
I wish you would have covered the Hudson straight six.
The stovebolt was just an old plodder, albeit a long-lived one. And the Aussie Hemi 6 was streets ahead of the old 4 bearing slant six. These two should swap positions in the chart.
Spot on , slant 6 horrible
The LM2 Duramax has a timing chain not a belt. However it does have a belt which drives the oil pump which does have to be replaced every 150,000 miles.
Missed the 5.9 Cummins! You side quested on GM and Ford diesels, then forgot the Chrysler Corp diesels!
Although the 5.9 is a legendary engine, Chrysler does not make Cummins engines. Cummins does
@@TOASTIBOI2001 I understand. However Cummins is American; and the title of the video is “The ULTIMATE American i6 engine Tier List”. I figure there should have been a best gas i6 list and best diesel i6 list. But as soon as I saw some diesels, Just thought he saving Cummins for last. But maybe it’s going to a whole video dedicated to Cummins ;)
Detroit Series 60 deserves either A or S tier man, I say this as a trucker & someone who talks to old timers about their older semis all the time. It is THE engine that built America to some large degree.
The stovebolt/turbo thrift was used in many more cars in Brazil than just the veraneio, it also powered the Chevrolet opala, the bonanza, the Chevrolet omega (opel omega) and many trucks and pickups alongside Brazilian made sports cars, that alone adds like 20 more entries into that stovebolt list
Just one comment. In the sixties shell oil did a long term study of engines and AMC 6 was one of the few that made the Million Mile mark in Taxi cabs without major overhaul or maintenance. (If memory serves, major maintenance applied only to having to repair lower engine internals or valve train.) Water pump, carburetor pr other external replacements did not count against them.)
That’s wild, 1 million no rebuild is crazy impressive. Thanks for the info
I had the amc 4Liter in my 99 wrangler. Great engine! Never an issue. Easy maintenance. 160k miles before I sold it and have regret it every day since.
Chevy had a decent straight 6 in the Trailblazer and 1st Gen Colorado (I believe) and I seen several in my shop over the years. My wife drove a 2004(?) Trailblazer and it was a nice SUV. The old Ford I6 4.9 was a beast ! Unbreakable ! AMC/Jeep 4.0 is another great one. I have a '90's Jeep with one.
Yeah never had an engine issue in my trailblazer the transmission on the other hand ......
Missing the Ford Dorset/Dover six diesels, predecessor to the ecotorque. All so the Brazilian diesels found in the larger F series and smaller L series trucks.
Some of those engines made before WWII and in the 1910's probably deserve S tier due to the little technology available at the time. Buick for one.
For the 60 series Detroit. Many owners got 1-2million miles before a rebuild. They are nearly bulletproof and over 1.2 million motors were made. A good numbe are still on the road too. It will outlast the ford 10:1. Many owners modified the motor and got 600-800hp 2000-2700tq. With ease. It should be in S tier.
Well I stand corrected, that’s actually insane. Begs the question why not make modern motors to last at least a little longer. Thanks for the info, cool to know
@@running2redline modern motors can last that long. But most will get a rebuild around 500k-750k. Which is insanely low. But it’s not unheard of for modern motors to make it 1 million miles plus
@@running2redline also with the 60 series when Glider trucks became popular (new trucks or few years old that had emissions equipment to get deleted/engine swapped) a lot of them had a 60 series because those motors were cheap because of many were made compared to Cummins or Caterpillar.
The detroit 60 series are really well built solid reliable engines. We still have a few as pump engines on our barges. I rode a boat that had them for main engines. They live a rough life out here on the water and give us almost zero problems. Speaking of detroit….. 6-71 could have done really well on this list. You absolutly cannot kill those things. It is a shame to see a solid design that has been putting in work since the mid 30’s to current being phased out because of its emissions.
@@frederickjeremy only issue with the 6-71 it’s underpowered and it didn’t get that good of fuel mileage unless it had a load.
Pre EGR/DPF 5.9 and 6.7 cummins are the best I6 engines period!
In other words, pre woke pest Era.
I'd put the Ford 300 into the S tier but other than that you are pretty much spot on. Having owned multiple Jeeps with the AMC Straight 6 I can absolutely verify that they are amazing engines. I love the Ford 300 as well as the GM Atlas. I had a TrailBlazer for a while and it was great.
Detroit Diesel was bought out my Daimler, aka Freightliner, a long while ago. The GM variants include ALL 2stroke Detroits, and the 6.2 and 6.5.
You frogot about the Legondaty Jeep AMC 242 Ci 4.0L Straight 6 which was in production from 9-1986-8-2007.
The hudson 262 straight 6 there was a taxi where I grew up with well over 700k on it those engines just wouldn't die
Nice job! Your results fell on a bell curve, as would one expect.
Tug MA-30/40s (airport bag tugs) have the 4.9 Ford 300s in em. My father knew some pilots who would drive them to their local autoparts store and get performance parts for them so they could drag race down the runway!
I had 06 SAAB 97-X with the GM 4.2 (Basically a fancy Trailblazer) and it was such as amazing engine, smooth, powerful, had a great growl, etc. The only issue with that engine is replacing the water pump as they go out very often with only one bearing supporting the fan and all that weight in addition to the belt hanging on that bearing essentially was a very stupid design. The thermostat is also way on and difficult to reach as well. Outside of that it is a great engine and would totally buy another vehicle with that engine as a second vehicle without hesitation.
Its worth to note that in Brazil the turbo thrift has been modified for up to 2000 hp with some people daily driving their cars on stock internals with up to 1000 hp
The AMC Six goes back to the AMC Rambler Classic Typhoon in 1964.
Thanks for this !
I'm more of a JDM guy these days, but the Ford 300, the Jeep 4.0, and the Slant Six are all absolute legends, and all 3 should've been S-Tier. My first brand new car I bought was a '95 XJ with the 4.0, had some good times with that.
The atlas 6 can handle a shit ton of boost, those things make over 700 horsepower
Another great I-6 engine that was killed off way too soon and had far too short of production run...I never understood, why they didn't use it as the base full-size truck engine, instead of the 4.3 V6.....
@@dyer2cycle they shoulda put in in the Colorados
You forgot the Fabulous Hudson Hornet. It had a 308 I6 and won a lot of NASCAR races in the early 50’s. 👍
I owned 2 Jeeps with the 4.0L AMC/Chrysler I6. In my opinion, it is tied with the 4.9L (300 cu. in.) Ford I6 as the best gasoline I6 engines ever made--anywhere. Few modern era (1996+) gasoline engines will often go over 350K miles with just routine maintenance. The 4.0L Jeep I6 will. As for the Ford 4.9L I6, it is legendary. My guess is that there are probably more of them still around today powering medium to heavy equipment than there are in trucks. Probably the best 4.9L Ford I6 was the '87+ engine with electronic fuel injection. It was relatively fuel efficient and was a very good running and reliable engine. Both the 4.0L AMC/Chrysler I6 and the Ford 4.9L I6 were killed by the asinine and excessive EPA emission regulations that came in the 2000's.
The 3.9 (240 cid) engine was also used in a few full sized Fords up until 1972. I remember seeing a 1970 Ford Galaxy with a 240 6 cid.
this might seem like a long shot but would a straight 8 tier list be possible? I know it’s a rare cylinder configuration but it’s an interesting engine with some history.
I’ll add it to my queue list, hadn’t thought of that one but I like the idea a lot, thank you!
I absolutely love my Jeep 4.0 I6 engines. I will grant that they aren't perfect, but are quite reliable with minimal love.
Also something to note about the 240/300s
Ford did offer the 240 and if you were lucky could get a 300 in ford's full size cars such as the ford galaxy or other large cars that would use the FE family of v8s
The 4.2L AMC 258 I6 will run forever. I have one in my CJ7. It’s 40 years old and it runs like it’s new.
you got a subscribe for that, twice you ranked one of my favorite engines in the s tire, AMC 4.0L!
Welcome aboard, thanks for the sub!
Hemi 6 should be in the S tier, amazing power and reliability for the time.
I've been waiting for this one lol
German v6 Tier list would be nice, if there are even enough engines to rank 😅
Ford 300 boss cross flow head and also chevy 292 cross flow.
The AMC six started as a Rambler 232 engine in the 1964 Typhoon models.
I work for a rental car company and the 3.0 twin turbo in the '24 Grand Wagoneer feels great and pulls this Behemoth nicely. Don't know about longevity as our fleet is only reaching about 20k miles.
Heres my favorites:
Chrysler slant 6
Ford 300 4.9
Chevy 292
Detroit diesel series 60 12.7
Vortec 4200
Ford barra
My personal favorites
Solid list!
Glad I've got a barra powered falcon in north America 😊
The Ford 300 is almost like an updated GMC 302 which ended production a year before the Ford 240/302 era began. There were multiple spendy aftermarket 302 cylinder heads produced. It's as if Ford produced a low cost version of those 302 heads.
Ford should bring back the inline 6, infact everyone should.
Very Good Compilation & Review - I just think the Chevy Atlas 4.2L is slightly underrated.
It's literally just as capable as the Ford / Holden Barra (notwithstanding the manufacture) and can & has been shown to be just as responsive to Turbo boosting (as proven by Richard Holdener, Nivilac & even Motor trend (among others)
Stout, Strong, and Potential for Drag strip quality Speed- definitely belongs solidly high in the S tier. Possibly the most under-rated and overlooked hot rod engine ever built.
I’ve got a ford 300 in my Foxbody! She pulls hard! Just as quick as a 5.0 Windsor and just about as much top end too
Apparently the OG owner ordered it that way It’s a 1979 model year glx hatchback
Saving the best for last, I see!
I think you were a tad bit harsh on those first two fords, I would have bumped them up a tier. Also, you missed Chrysler’s new Hurricane 3.0 inline 6, which comes in the grand wagoneer, and the 2025 ram 1500
a japanese i4 tier list would be interesting
The Australian Chrysler hemi 6 cylinder engine was originally developed by Chrysler as a replacement for slant 6 in trucks. But they never went ahead with it..... Chrysler Australia developed the engine further and use it to the early 1980s
I noticed you didnt list the Dodge W series trucks for the
/6. Lots of W series trucks were build for military crew cab trucks in the late 60s. My 67 crew cab does have a /6
Hemi Sixes were also available in the Chrysler Centura.
You should add sound bits for each engine in your videos.
Still waiting for the ultimate V8 Rest of Europe (including GB and IT) list :)
I watched this fpr tge Slant 6 rating. If it made the list!?
Love the respect in the S rating.
I loved mine! My favorite truck!
The Ford 300 definitely belongs in the S tier. Also the 3.9 L 240 ci variant of that engine family was available in Ford's full-size cars is the base engine But overall I think the video was very good
I still drive daily a 1995 ford f150 4.9 300 with over 320k+ miles on it mated to a 5 speed transmission. Best engine I've ever owned and most reliable and when something does go wrong it's dirt cheap to repair at home when it does die I will import a ford barra engine and push on but that will be a long way off the 4.9 is still running strong. It's definitely a s tier engine not an a tier.
You forgot to mention that the slant six came in the early ramchargers
I have really high hopes for the new hurricane I6. If it fits in a Jeep Gladiator that's what I'm putting in mine. It's far too new to put in a tier list though.
Unfortunately I missed that one, now that I look into it though it looks promising
3.0 duramax have oil pump belt but timing chains for the camshafts and high pressure fuel pump
Please make a JDM I4 tier list please I'm begging you
Please do american v8 tier list. So many engines. From flathead ford to modern LS
I did one way back but it was actually my first ever tier list so it’s very incomplete. I will likely redo it to include much of the older stuff and adhere to my newer format
forgot about the cummins i6!
Nope it’s only engines they made dodge does not own Cummins they work together
@@paulrosenbaum2719not to split hairs but the rules of this video are quite odd as a “American” list including Australian products. Even to just add it (Cummins) to the end of the video as an honorable mention since Detroit diesel is featured. Cummins is an American made i6 so if anything, it deserves to be on this list just as much as the Australians, not to mention its heavy influence in the Ram.
@@TrucksForCanada I agree with you 100% it should be on this list
And if we're doing heavy-duty diesels, gotta include CAT, Pete, Navistar and Mack. Sooo...maybe not?
@@greghanson3495 Why not?
going to have to make this video again after the new Charger L6 comes out.
Barra the world m8!
Truck 6 should be in S teir everyday
The ford 4.9 is crazy reliable even when modded
Have you seen the power Nation video they did on one of those? They took one off of pump from 88 horsepower to well over 500. It was absolutely Wild
It's enough to make a grown man cry, probably should buy a turbo falcon huh
The late model SOHC falcon engines called Intechs are sometimes even more reliable than Barras. Would maybe deserve S tier.
So when are you doing the V4 tier list? 🙂
V4 would be predominantly motorcycle engines, but I’ll be doing inline 4 engines shortly. Within the next 2-3 videos I think!
The Falcon Six wasn't great in it's original 144 CID version..it was absolutely gutless in both horsepower and torque, and had a weak 4 main bearing bottom end....
Can we get a i4 top tier? Thanks
GMT350 prices are gonna go up now, aren't they?
The series 60 definitely should be A or S tier, I get to work on em time by time and they where so very much ahead of there time it’s not even funny! Only basic maintenance and your golden. Of course there not the greatest out there, however if I was to go buy a semi today I get anything without a 60 series.
I am guessing that the new Stellantis Hurricane I6 is too new and not yet well known to be on this list?
There's now a few 300s that are pushing 1000HP turboed
And the ones rocking Allen Johnson billet heads are running in the 800-820hp range NA
As for reliability and duraibility, the closest engine would be the toyota 22r and re, otherwise the 300 is thee hands down most durable gasser made, have 1.04 million US miles on my 87 f350 without being opened once and had 650k miles on my 83 which i pulled due to cyl 1 eating itself for about 40k miles running on 5 cyls both highway and in town and still pulling cars for my auto shop
The 300 simply cannot be beat by anything that has been produced as of today or earlier
Only a new design would be able to compete
Oldsmobile 11.6L with 84hp. Are you sure Harley was in on that design?
This guys analysis makes me think that he was high. Ford 300, AM 6, Slanty, and GM 6, are hands down the best.
The Slant 6 is probably superior by everyone.
I’m confused how I was off then, I put all of those engines near or at the top, seems pretty spot on to me
The Ford 4.9 should be S tier for sure.
Also the atlas can make crazy power
Sad you did not add the new Hurricane engine from Chrysler....
You forgot the new Chrysler hurricane i6 in the grand wagonner
@@alainaguilar9938 we'll find out eventually, so far as a chrysler tech, it seems their thermostats like to take a poop, which is not simple to replace lol
300-6 needs to be in the S tier.
Jeep 4.0 straight six rules them all, fight me
I will say it's a great engine but 4.9 Ford is what I own and it's just as damn good as the 4.0 straight 6 but the 4.0 is just a bit smaller. I've got friends with the 4.0 with over 300k on them just like my 4.9 with over 300k and a 5 speed manual mated to her. Shes my daily driver.
I’m very surprised the zephyr 6 was in here I swear almost nobody knows this motor
