The tow truck i used to drive had a 6.4 that thing was a real power house. It was impressive. The tow truck was also on the third engine when I was driving it

Once deleted and studs installed the 6.4 was a monster with the tunes available during its time. Innovative offered a tune that was good for nearly 350HP over stock on tune alone. I would see 58 PSI of boost. No tuned diesel since has impressed me as the 6.4. Most of course is due to not being able to delete plus tune due to our wonderful EPA. I'm truly glad I got to experience such raw torque before the EPA crashed and burned deleting diesels. No fuel additives or regen. 0-80 mph it was quite a ride. Miss that truck. I had a 2008 F250 FX4.

Hey, Im a former International tech, the 6.4 was a dumpster fire of an engine, and im pretty sure the "engineers" that designed it were huffing the fumes that came off it.

6.7 power stroke is better overall engine. But When it comes to raw tuning power before blowing up 6.4 is more powerful

I have both the 6.0 and 6.4 fords, really love my trucks no issues at all. The only very minor issues on both is just that one has gone through 4 engines and the the other through 6. Still running good and love the power!

Why are you so underrated i love your vids man keep it up

I have a 08 6.4 got it deleted at 200k it has been a good truck always gets the job done and keeps on going.

I loved my 2010 f350 Harley Davidson... until I cracked a piston using h s tuning lol

6.7 by far 6.4 is just a punched out 6.0 with common rail system, same head bolt issues from the 6.0, just takes more power to find out about it, but the fuel system is capable of flowing so much it can easily destroy itself, so 6.7 is the only choice in this comparison

I loved my 6.4 powerstroke it was custom tuned running a mild tune i kept up on all the maitnence, it was a great truck loved the power, never gave me a problem, other than i replaced the radiator. But i dumped it for a 16 6.7 platinum before it was gonna set my bank acct. back sooner or later it was gonna get me. I love this 6.7 damn the power i of course deleted with ezlink, tyrant tunes, mpd sxe364 non vgt and beefed up the trans with a midwest. I can't leave nothing alone lol

There’s so many people here who are gonna disagree with me on this but the 6.4L powerstroke is the only ford engine I’ve actually had good luck with. Also the 2 valve 330 is another one I like and everybody else hates both.

Funny the question is even being asked..its a no brainer here.

I'm good with my 08 6.4, best truck iv ever driven. Did have to delete egr and dpf which wasn't difficult even for a rookie mechanic like me Thnx to tech ron, powerstroke bald dude, and the military dude on injectors . Help videos are awesome.

You forgot to mention that the 2011-2014 6.7 Powerstroke is very famous for the crankshaft breaking even under stock power because they don't have a bedpan setup.

I always find these reviews years after buying the crap that was supposed to be an upgrade from the crap that preceded. 2008 6.4L f350, 216k miles, still running. Looking at 2020 models now.

I love my 2019 6.7 Powerstroke!

Good video bro!!!

2020 F-350 w/6.7. The torque along with the 10 speed was an amazing improvement with industry leading 0 to 60 times in a truck that scales at 8100lbs. And no mistake about the ability to pull loads with 475 hp and 1050 fpt. You see very little difference between pulling 10,000lbs vs the full 21,000lbs.

Great video very Informative

Love my 6.4,don't beat the shit out of it every time it's driven,don't put a ridiculous tune on a basically a stock engine and the damn thing will be fine,it's simple

I have owned 7- 7.3L, 1- 6.4L, and 1- 6.7L . As far as which one is the better built motor it's hands down the 7.3L . 334k on the current one with several mods and 410hp. Which one has been the most costly to operate, definitely the 6.7L. It's a nice quiet pulling platform but has already had one catastrophic CP4 failure that has really turned me sour on this truck. Lastly my 6.4L KR is a beast of a truck. Crazy fast and pulls like a train. It had 248k on it when the valve train imploded and wiped the motor. Full UCF machine shop rebuild and ringed heads top it off. All that said the 7.3 has been maintenance items that I turned into upgrades. The 6.7 has me disgusted. The 6.4 is all smiles per mile.

LB for LB a 6.4L will embarrass a 6.7L any day that ends in Y. I'm here because I traded in my 6.4L three days ago on a 6.7. That being said, both are beautiful but a 6.7 cannot touch an equivalent 6.4L in power application. It just does not have the balls or the ass to drive it home. Great video man, I learned quite a few things that i did not have in my extensive knowledge of the 6.4L.

6.4 owner with no problems ever. Depends who owns it and takes care of it people. Everyone has their opinion, so does this guy making the video, but any engine is shit if you do not properly maintain it. Like I said, my 2010 is still going strong to this day with over 400,000 miles on her.

You must never heard of the 6.5 Chevy diesel 😂😂😂. Those things were ticking time bombs 😂😂😂

Great job.

Just drove a 2012 F550 6.7L to 200K, flawless reliability. Only real issue was broken exhaust bolts at 180K. The truck I drive weighs 20,000 lbs so Always working hard. Engine starts and runs like a champ.

My first Ford was a 2010 6.4. I bought it already deleted and it might be the fastest thing I’ve ever been in. I now have a 14 6.7 and I’m deleting it this weekend. As of now I’m going with a bigger turbine wheel but will that turbo off a 6. 4 for on a 6.7?

Wow thank you I needed this video 👍🏼👍🏼

Can you make a video about the Honda 1.5T L15B7 I have a 8th Gen Si debating on switching out these new engine design

Subbed because informative, simple, a solid presentation, and you speak clearly and it's just overall a good quality video. Watched a couple other of your videos too. I don't even like diesels, or trucks for that matter. 😂😅, Guess that shows your videos are rather capturing.

You forgot about the fuel pump system it's a common-rail. With that in the turbo that's what makes the 6.4 be able to do 300 extra horsepower with just a tuner exhaust and cold air intake

I'd love to see a review video on gm 6.2l diesel vs 6.5L diesel

I want to see a video about the 6.9/7.3 IDI vs the 7.3 Powerstroke.

There are more positives to the 6.7L design such as its steel pistons introduced in 2020. Steel is used in race engines - stronger and handles more heat and pressure the aluminum pistons. The 6.7 is a good engine that gets revised and updated from time to time making it a viable alternative to the Duramax and Cummins. My ‘02 Duramax had only 300/520 TQ. It’s amazing how torque and HP have increased significantly in these new designs.

I had a 6.0 liter F.O.R.D., if I pulled a trailer, the 4 bolts around each cylinder ( should be SIX) would allow the head gaskets to leak. This put 2,000 psi power pluses into the coolant. The radiator cap would TRY to release the over pressure ( 16 psi cap). That pressure would go to the plastic bottle and blow antifreeze on the window & the cars windows around me. Called a tow truck to haul to Ford dealer (still under warranty) the FORD tech. said everything is fine. No problem. Ford refused to replace headgaskets. The next day, towing a trailer, the coolant pressured up and exploded the E.G.R. cooler. This time I did NOT call a tow truck. I drove the P.O.S. home. The NEXT day I bought a CUMMINS, that now has over 500,000 miles. Change the oil, fuel filter, water, pump belts & rive for million miles. The cab of Dodge has NEVER been off the chassis. CUMMINS.

I can’t lie. I love my 6.4. But I’m careful with it. I don’t hotrod my truck at all.

Just fyi. Most modern common rail diesels will fuck up if there is water in the fuel. That's why most diesels have a water-fuel separator

6.7 has been in production for 11 years... that kinda says it all.

No. The WORST diesel in automotive history was the GM 350 diesel. The 6.4 might be the worst engine put in a Ford, but the GM 350 holds the title for being the worst.

My 08 6.4 has 300000 on it is still the fastest truck ive owned full delete mild tune but is a money pit 6.7 on next one

Okay now circle back around to the start. 7.3 vs 6.7: which one is better?

Good video.

All I hear about the 6.4 is how bad they are. But those Harley Davidson editions are beautiful... worth it?

@Salinas photography For the rollers in this void

"One of the worst diesel engines in automotive history" Yes.

Anyone who uses the term "throw away engine" is a youtube mechanic

Lmao I fucking love my 6.4

Client of mine owns a 6.7 cummins soon be 800k miles same motor since new ,fixed some oil leaks . We put in 3 transmissions so far trough out the life of the truck. Towing over 30K equipment to Job sites all around the state with a tunner. All it takes to keep these trucks go, is to maintain them and be smart about the tune. Too hot and it will burn your wallet.

Everyone commenting how the 6.7 is not as efficient, you do realize regenning kills mpgs. Deleted 6.7s can get up to 25mpg highway depending on the rear end ratio

Found a 6.4 for a great price! Guy told me the water pump replaced and drain and fill on coolant, both fuel filters replaced and the fuel water separator bowl took apart cleaned, and reinstalled. The truck is all stock and has 248k miles. The truck is nice except for a ding here and a scratch there and a hole in the driver's seat. It's a lariat to. Really uncertain. Any advice

I've always known the 6.4 power to have sequential turbos not compounds. They work in sequence 1 goes and than the other

i really need some advice from someone that really knows i have a chance to buy a 6.4 at a ok price but i need it to haul stuff from coast to coast with 144 thousand miles and its pretty much my only option, but i cant afford to just buy a truck if its not gonna do what i need?

I think that the 6.7 is a very good engine when you remove the emission systeem and use good diesel it really dosnt have an issue with the engine itself

My 6.4 has 319,000 miles. It was deleted when new and a tuner installed. Incredible power, empty just boils the dual rear tires and buries the boost guage. Of course I put all the factory emissions equipment back on it since I've owned it! Transmission at 278K only problem.

Its 2023 and im still driving mý stock and Deleted 6.4. But i just did a rebuild on the tranie. and shes ready for another round ❤🎉

Update on the 6.7L Powerstroke’s output numbers HP: 390-475 (500 H.O.) TQ: 735-1,050 (1,200 H.O.)

So that alone being said powdered metal connecting rods. Someone explain to me how a 6.4 is good for a 1000hp I’m assuming at the Crank And a 7.3 connecting rods are good for 400 450 max. Let me know it an honest question

Cab off repairs are common between ford ram and gm

The 6.4 if you delete emissions and maintained them correctly and didn’t tune them heavy where dependable they just where horrible on fuel economy the 6.7 is great on fuel with the same power of the 6.4 and less maintenance issues if you want to delete emissions and hold up better with high tunes due to the torqshift 6 speed from 2012 and up that literally is the f750 commercial truck transmission.... I’ve had Cummins duramax and powerstrokes the new ones are all tit for tat but the more refined one nowdays is the ford as far as good all the way around on power fuel efficiency power distribution/ turbo lag ...cab and chassis/suspension quality

The 6.7 is the modern version of the 7.3. My buddy has a SXE 364.5 Non VGT turbo on his 2014 6.7 and it honestly sounds like a 7.3l.

Even I think both those engines are great in the 1980 to 2011 Ford Crown Victoria's and Police Interceptors all the time.

It all comes down to the quality of their engineering department....a.k.a how much they pay their engineers. Ford crushes International on that one. Cummins is first class organization as well and their products reflect that. I do own a 7.3, but what have you done since then international?

Good Video man, Do both usesame trans and is a change out possible without computer, ecm, you know what I'm getting at. I love this truck so in your mind is it worth it. thanks I'm Jake at Jakes Auto rebuild

Too bad they couldnt incorperate the 6.4 turbo n pistons into the 6.7..... I wonder if it would work?

What is a good tune for the 6.4 engine?

Had a 2008 6.4 , pulled like freightrain ! Always something wrong with it !!!!! Caught fire and burnt about a month ago , total loss ! My first and last diesel truck ! Replaced with a V 10 , my second V10 .

How about a non bias comparison between the power stroke and a duramax.

Can you use the 6 4 turbo system on the 6.7????

7.3 and 6.7 engines are the best

6.0 was way better on fuel than any of the other engines we got a 6.7 at work and it's a diesel hog under load my 6.0 under load does way better I get like 14mpg 240,000 miles and only thing to fail was high pressure oil pump and that was fixed with basic hand tools

Cough "Maxxforce" Cough

7.3

No discussion of unkeyed bearings? Big problem on the cab-chassis 6.7's I've heard. Correct spelling 'Bosch'. Description missing a word before 'most' above... the 'most' what?

The 6.4 powerstroke. The most expensive throw away engine ever built.

My 6.4 powerstroke is the best truck, have a cold intake with a tunner and 250,000 miles, no issues..

Great video bud. oh….Bosch* =P

Literally all of the problems with the 6.4 can be traced back to the ridiculous emissions equipment. Delete the emissions from the 6.4, change the fluids and filters regularly, and it can be just as reliable as any other powerstroke. That said, when mine blows up a 5.9 Cummins will go in.

I'm pretty sure Bosch does not have an e at the end

Awesome stuff. I have a 2015 F250, 6.7. No mods except S&B cold air , and 5" DPF back exhaust. For "emission compliant"? Those simple mods made the performance bump up noticeably. I usually drive a Pete with a C-15. Diesel rules.

So the Pistons are the weak point of the 64. And rich fuel mixture which leads to heavy sludge sounds correctable.

Do lly vs lbz

Will a 6.7 hook up in place of the 6.4 or not

hey there #DustRunnersAutomotiveJournal Love your videos , they are full of goood and reliable info, how about a video about steering, suspension , drivability and comfort. thnx again

gotta make deletes to 6.4, and then its fine.

The 6.L was a good engine but the only problem was the oil cooler the broke down and damp the water i your intake the 6.4 is same engine as the 6.0 the only difference in the top of the engine

Not even a question to be asked if you know diesels. Don’t even need to watch this to find out lmao.

Only problem with the 6.7 is that darn cp4 fuel pump. Other than that great motor

This explained it from top to bottom. I've been looking at 6.0, 6.4 and 6.7 powered trucks and was really curious why 6.4 trucks are next to nothing and yet have great history with them. I knew the 6.4 sucked but what clued me in on how bad was when PowerstrokeHelp straight up told people who buy them to stay the hell away because if you're dumb enough to buy them, you're dumb enough to get stuck with them. But this went into a lot more detail.

Non indexed main bearings on 6.7

The 6.7 is actually a Hot V configuration

honestly, i couldnt tell you the last time i saw a 6.4 on the road.

7.3 was the best , then the 6.7 for running stock (no bulletproof)

I've got an 08 (Job 1) 6.4 which is completely stock and has always had all scheduled maintenance/service done religiously. Yet it still has been plagued with problems, all being engine related. Leaking radiator (replaced), leaking head gasket causing over-pressurizing of coolant system (cab removal repair), oil leak at bedplate (cab removal & engine removal repair), HP fuel pump failure (cab removal replacement), exhaust temp sensor failed (1 failed but replaced all 3) including a new DPF, exhaust temp sensor failed on up pipe (replaced). All instances, except radiator and oil leak, took several trips to dealership service dept. in order to diagnose because no codes were initially stored and it only gave us problems when under load while towing our RV. At these times we would experience reduced power (limp mode) and/or blowing white smoke, both of which would temporarily go away after doing a shutoff/restart. Fortunately all covered under extended Premium Care warranty, which I've renewed twice because of trucks history, at $3200 a pop. Switching to a 2021 6.7 when current warranty expires the end of next year. The 6.4 was a disaster as was the 6.0. Ford Motor Company did the right thing by ending their relationship with Navistar. So far,, I have heard/read nothing but positives about the 6.7 since its rollout in 2011, both privately owned and with fleet trucks.

There seems to be one key point missing here. Ford was responsible for the majority of the problems with the 6.4L Powerstroke. Ford was already planning their own engine, and the 6.4L was their experiment into making a diesel engine run. The 6.4L wasn't the last straw. The 6.0L was, and Navistar already knew it was at the end. The 7.3L and 6.0L Powerstrokes were essentially the same engines Navistar put in International trucks, just a different color of paint. Ford bought a cheapened version of the 6.4L longblock from Navistar. The turbochargers, fuel system, EGR, DOC, DPF, etc. were all Ford's own doing. I'm not saying that the 6.4L used in International trucks wasn't a piece of shit in its own right, but you can't blame Navistar for how bad it was in Ford trucks. Knowing Ford was soon to be gone, Navistar came up with the TerraStar truck, equivalent to the F450 and F550, in an effort to recover some of the market for their V8 engine as a justification for continuing to produce it. Obviously that worked well, given that the V8 is long gone, the Indianapolis Engine Plant and Indianapolis Casting Corporation have been leveled, and that class of International truck is now a rebadged Chevy.

Just redo the 7.3 powersmoke. Old school 7.3 with a modern twist. No replacement for displacement

6.4 is disposable. Rods and wrist pins missing bushings. Built to save money. Take very good care of it and do not tune it and it will be okay. The engine is virtually non rebuildable once it goes. Yes they're exceptions but it's a disposable engine

They " build " their own engine

I love my 6.4 ,,it has an egr delete and a dpf delete,,tuned with mini maxx h&s,,I’m getting over 650hp and 1300tq,,Never had an issue,,207,427.4 miles,,how do I know,,cuz I’m in it now,,very dependable truck,,,

My 6.7 goes through more fuel than my old 6.4..... just saying
