I wish GM would bring back the big block motor, redesigned and improved with today's technology!
john kertzman dont worry ford is bringing back the big block.
The 8.1 will probably be the closest thing we will ever get to that
will it be a BBF clone like this LS is a SBF clone? seems to be the best way to make a fast chev motor, throw out everything chevy and copy a ford
mikeyjock the corvette is now a mid engine dohc car and theyre going to call it the corvette GT lol. Not to mention the ecoboost camaro, they cant stop copying ford!
They need to bring the 454 back that makes over 500 ft lbs torque and over 400 hp but that would be a terrible gas hog and the government today won’t allow that
The truck news within the past week alone has been insane. Love it and thanks for the great coverage 👍
Yes America makes awesome trucks and until around the year 2005 I didn't care about trucks until I got a old Toyota 4 by 4 that truck was so useful to me especially a person who lived near Lake Ontario. But in the Spring and summer and fall I would take it out on the trails and because it wasn't very big I could go just about any place. Approach and departure angles were awesome so I could climb steep hills my gosh that Truck was great. When it had 252000 miles on a it was still running great until my mechanic set the timing wrong and destroy the engine. He took care of me and was fair but boy I missed that truck 6 cylinder engine 5 speed stick manual locking front hubs. Little beast. Now days I look at trucks even used With decent miles and even on my above average income I completely Choke from the insane prices.
Get rid of the stupid background music! People watching these videos are entertained by the technical content and discussion, not silly music. It detracts from the video.
No shit!
@Rick Simpson LMFAO, Like a FORD FanBoy... You can't even get your info correct, not even about your ford engine. FYI, the New FORD V8 is a 7.3L (NOT 7.2L) also a OHV V8 so all the Ford guys talking BS about pushrod can now take their foot out of their mouths.
JerseyMikeP Rick Simpson seems like an idiot but let’s not forgot GM is trash and Ford is at minimum significantly better than GM
What I’m finding interesting is that GM and Ford are recognizing the need for a good gas engine and in my opinion it should have happened a coupe years ago but it’s here now .
The 6.4 is a pretty solid effort.
Tangy Tangerine so true tho 😂😂

,6.0 pulls like shit and drinks gas like crazy
My 1999 Chevy dually 4x4 with a 454 vortec with 285.000 will drag your shit 6.0 anywhere
Fleets love the old 6.0 gas engine. I wish GM would go even bigger like Ford.
My uncle owns a contracting business and used to have a 2004 Dodge Ram 2500 with the 5.7 Hemi and today he has a 2010 Silverado 2500 with the 6.0. He got rid of the Dodge because he wanted a utility bed and just a new truck in general. He tells me that the Hemi with its older age and smaller engine pulled a lot better than the 6.0 and was more reliable. He had 280,000 miles on it when he sold it and got the Silverado and it was still a great running truck. Not saying the Silverado is a bad truck as it has helped a lot, yet it is an interesting spectacle to say the least.
I have it in my 2021 2500HD Custom...remember your moving a tank but ...power is great and smooth and I can tow anything. Adding a cold air intake and new exhaust and I’m good. Great gas engine of old and new 👍🏾
Hey buddy,
I am thinking about this engine in my next truck, how many miles do you have on that engine?
Any problems with the truck or engine, transmission?
🍻Cheers
Cai does nothing but filter worse, unless 3.6hp at 5k rpm is important to you, fyi. Truck comes with one from the factory.
4:29 Let's drive a scissor lift over there and act like we are working so we can get on camera!
HaHa right, Silly guys.
We want more 6.6 gas content!
It might be an old fashioned opinion but they should have brought back the Atlas program with a beefed up inline 6 with vvt.. that old 4200 is an absolute tank and it will run 600hp boosted without breaking a sweat.
Upvoting because IN-LINE 6 !
The i6 is the best engine platform ever created for both torque and longevity. IMHO
couldn't agree more!
Forgive me being naive about that but is that the engine that was in some of the early 2000 S UV's as well as trucks? Referring to the 6 cylinder in line known as the 4200 I guess so 4.2
John Degroff Yes, he is referring to the Atlas platform aka Vortec 4200 found in the Trailblazer/Envoy and Colorado/Canyon SUVs and trucks.
So Direct Injection, but no Port Injection also? Me thinks there's going to be some carbon issues like some of the other GM DI systems
With any DI systems, not just GM
@@ThisIsInput Some are better than others, but GM seems to have alot of problems with it, VW as well
Just vent PCV to exhaust and have no buildup.
FORD got it right with their new 7.3L V8. They are using port fuel injection👌
@@Suction_ The GM trucks that have went to DI like in the 5.3 and 6.2 have done extremely well with carbon build up. Their earlier 4cyl and 6 cyl engines had early build up though. They learned from that and came out with a proper PCV system on the 2014 and up trucks that really helped.
Ordered a new Silverado HD with this motor. I can’t wait to see what it can do!
It's got nothing on the 7.3L Ford.
How do you like it now?
@@chriseast030691 Ford keeps scrapping every single engine and bringing new ones every 2 years. Yeah I'm sure they got a keeper this time.
@@imyourhuckleberry4547 Elaborate please, when was the last time they scrapped an engine within 2 years. You know nothing. 5.4L was out from 98' to 2011 same with the 4.6. The 6.8L V10 was around from 98 to 2019 ( which is what the 7.3L replaced). The new generation has been out since 2011 to present, 6.7L, 6.2L, 3.5L EcoBoost, 5.0L coyote. Almost a decade all these engines have been around This is the only new Ford engine in a Superduty since 2011 and you Can still get 6.2L and 6.7L. So please, elaborate on where they have been scrapping engines every 2 years?

@@connerbutler1077 hell yeah
@@maynardreed4036 Don't forget the gallon of oil they would drink between fill ups. The 6.0 was an absolute gem when it came to reliability, the 8.1 didn't offer much more in the terms of grunt but did drink a lot more fuel and oil.
@@WilliamStewart1 I don't know man. My experience has been the exact opposite. Considerably better power with only marginally higher fuel consumption.
Variable oil pressure? I don't like the sound of that.
It just means extra chains and gears to time whe the oil pump fails. But really its meant to run low oil pressure at idle and increase oil pressure under load
Its meant to keep the oil pressure consistent without the use of a relief valve, reducing the power required to run the pump. Its variable displacement, I doubt they are adjusting the pressure in response to load. The pump will compensate for hot, thin oil and pump more volume to keep the pressure up. Edit, looked it up, and they are controlling the displacement of the pump using load.
I hope they don't have issues with keeping the pump primed like the Ford engine.
Old days are gone .... cylinder deactivation was the same worry
Just like 5.3 and 6.2.
No that's not how this oil pump works. It's a vane style, eccentric oil pump that can change its displacement based oil pressure requirements. Every Gen V smallblock GM makes today as well as their latest 3.6 V6 uses a variable displacement oil pump. That's close to 5 million engines on the road with this oil pump.
How is the new Ford 7.3 a copy of the LS engines? Because it’s a pushrod? Ford has been making pushrod engines as long as GM. Ford said the main reason they went with pushrods is because it allows for a bigger displacement in a smaller package. It’s also a replacement for the V10 engine they’ve been making since the 90’s. Like the V10 it’s not a good engine for high performance but optimized for pulling, similar to a diesel. Interesting that the Ford engineer stated that one reason they went with port injection is because they know a lot of customers will be idling their trucks for long periods of time, especially in Alaska and extreme cold climates where it may run for days without being shut off.
The 7.3 is not a copy of the LS - the LS is a copy of the Ford 427 FE used in Nascar in the 60s
The LS was designed by a hard core small block Chevy engineer that fixed the 10 problems the old design had. The rod knocking FE design with oiling problems, I think not. Crap. Ford can make a V8 but they can't make it last. Thanks to a Mazda design, they have the EcoPoop engine bolted to a ZF6 hp26 transmission ( AK 6R60/80) can't even make a trans worth a shit. So they go to GM Hydromatic to use their 10 speed to put in they beer can shit box pick up. I wonder if Ford is still using plastic pistons in their disc brake calipers like they used in the Exploders. Don't even get me started. 32 years of wrenching, GM, Dodge, Ford all have their problems but Ford takes the crown.👑👑👑
@@cliffordcullen1687 my 35 years of wrenching says you are a dumbass. The 10 speed auto was a joint design between Ford and GM.
and the LS is a SBF copy
@@cliffordcullen1687 hey dumbass, ford was the lead engineer on the 10 speed so it was gm that wanted to partner up. Get your shit straight before running your trap.

@@noesalgado5038 only 17k on my truck, towing most of the time , RV and Boat the weight of both around 7k pounds. So far so good. Right now I like my truck.
6.6 liters. heck its the small block 400 back from the 70’s. Siamese cylinders and all.
carlorocky ehhh with many many modern updates forging processes tolerances all that has drastically changed. Stainless steel manifolds is pretty awesome too.
This engine has a slightly smaller bore and longer stroke than an old school 400 sbc. This engine 4.065 old engine had a 4.125
Yea, on side of trans am 6.6
so this is essentially a gen 5 block moved from AL to cast with extra cooling passages (havent paid that much attention to the block decks of both to really know) and a slighty larger chamber that dropped the compression from 11.5 to 10.8.... fancy.... but if you have all this proof that direct injection engines will get clogged intakes, why not use a dual injection system? like you already have a truck that pretty much starts at 30k for the base models why not put a little extra money and engineering for reliability?
@emark24 The GM trucks that have went to DI like in the 5.3 and 6.2 have done extremely well with carbon build up. Their earlier 4cyl and 6 cyl engines had early build up though. They learned from that and came out with a proper PCV system on the 2014 and up trucks that really helped.
Quit spewing BS. They engineered and specifically designed a new ventilation system for this engine that separates the oil from the air so the gas can recirculated without the oil, thus fixing the issue from carbon issues with some other DI engines. They put millions miles on these engines for testing, they would have seen and fixed the issues you claim to relevant for these types engines.
@@zimks i havent spew any BS and in any case i claimed to be someone knowledgeable, i just stated a concern i had about it from watching other manufacturers struggle so bad with it that they had to use port + direct injection together in order to control the carbon build up they had, furthermore they havent talked about how they addressed that issue (doesnt seem to be stated anywhere and its the clear elephant in the room) so if you could send me the source from where you got this i would be very thankful!.
on a side note theres no need to be that agressive i know how engines work as i make a living out of repairing them, im just curious about the engineering

400 cubic inches, baby! Like the displacement sizes of old. No biggie...just sounds kinda cool.
Exactly
Not sure about that direct injection... Think I would take the new 7.3 that Ford is making over this
Less cylinder wash thus longer life with the Direct Injection.
Not a fan of ford, but that new 7.3 actually looks like a very dependable engine based off of the construction facts.
direct injection has been out since 2000. You can run higher compression and get better fuel mileage. Whats there not to like.
I'm a gm guy and agree with not going with direct injection. It's not reliable enough yet . I'd go with the 7.3 ford
@@TheCamaro5 . What's not to like . The reliability part of it ! . Carbon on the intake valves and increased injector failures

I believe it ! I had a 2021 Tundra and it was rediculous how it drank gasoline. I look at people on the road with Tundras now and I have no respect for them.
I remember how exciting the 6.6 liter was on the Trans am! Everyone was in awe when those numbers were on the hood.
Im so sick of phrases like best in class, industry first, and no compromise engine. It’s just a big pissing contest, and these engineers are really just marketing puppets for management. The manufacturers control what, how, and when the journalists respond to these announcements as well.
Chad Bell you are right, but engineers need something to shoot for. Competition does improve the product. These are amazing vehicles because of all the revisions.
Bring back the affordable bare bones work truck for people in the light duty service industry.
Larry Norsworthy Yes and in Suburban and Tahoe
Why does it sound like he is hiccuping every 3 words? Also, the memorized bullshit heavy sales pitch isnt impressing anyone. Just be frank and drop the marketing.
He doesn't stop talking ,so he is taking small breathes
Had a big lunch
maybe he is an actual engineer and not a salesman. one can hope
And that “if an engines down our customer didn’t get paid” I can assure GM didn’t care when they had my truck for weeks attempting to find an electrical gremlin
Talking on camera and making sense and being smooth is tough. Guys like him are not used to it. It has to be learned. He is an engineer. Give him a little credit.
Forged pistons, rods, and crankshaft! That's what I like to hear!
Yeah cam and Blower that might make into my 2014 C7
15 megapascals ??? How about telling us in PSI . by the way 15 MPa is 2176 psi

@@midnightrider1087 . He said mega pascals.
@@midnightrider1087 No, he said MPa. KPa wouldn't inject fuel in a DI application.
Technically he said KPa then megapascals referring to different pressures in different parts of the system. Go listen again.
What the hell was ever wrong with port injection? Seriously what does DI get you? 0.2 mpg? 6 HP? dirty valves? Is it worth it?
I had the pleasure to work with Mike for a short time, great engineer! Congrats with the new launch!
Bring back the 8.1 and while your at it, how bout a 6 speed manual trans. Then, get rid of all the junk that doesn't do anything or won't work in two years after somebody buys the truck, and then maybe I wouldn't mind buying one. I'm a GM guy, but Ford is looking better for the most part to me.
Same here. It's hard to overlook the new 7.3 gasser it's so simple for such a new engine
the manual trans would be nice, but they just cant handle the torque from the new motors. they have to be pretty long by design to make it last
My 2002 GMC 2500hd regular cab has the 8.1 with the ZF 6spd. manual. I have owned it since 2003 and now has 172k miles on the original clutch and TXM. I do work it pulling trailers with sometimes 4-6 ton loads, and it is my daily driver. The reason I would be happy with the big block and manual TXM is mine has proven to be very reliable to me and I am very happy with it. It matters how you drive them and take care of the mechanicals to get longevity, as well as being able to recognize when the abuse is too much for what you have. I might add that I have upgraded engine power with a programmer, Gibson exhaust, cold air intake, and throttle body spacer. This was all done shortly after I bought the truck.
Thanks Andre 4 excellent reporting once again I'm not a Chevy guy but I must say I'm impressed
I have a 2009 cobalt ss, I sure hope GM has come a far way on direct injection because its a nightmare on my car. I have walnut blasted my intake valves twice now and only have 90,000 miles on the car, the carbon build up from old gm direct injection is wild.
Andre is knocking his segments out of the park! nice job again buddy!
That man is a very well spoken engineer! Awesome video! Thank's for giving us some insight as to where our beloved GM is going!
That’s why they pay him. He said he was just a member of a group
Alot of technology and expensive parts to break. I just hope these are as good as the 6.0
Why don’t you ask them how they plan to deal with carbon build up?
I agree. Direct injection on non turbo and turbo engine are great except for the build up on the back of the valves. Thats why Ford and Toyota have added port injection back to the direct injected motors. They also did that so they can use what's best in any situation. Port is good while under no load idling so you don't have to listen to the DI clicking away. He should have asked that question. They have talked about the different types of injection before and the pros and cons.
repairvehicle I know but still, carbon build up is one of the biggest issues with direct injection and it’s a big deal once you hit 100k+ miles. It’s not covered under warranty either.
Don’t believe the direct injection is as troublesome on a naturally aspirated engine. Without a the increased cylinder pressures, the intake charge will be less contaminated with oil vapours.... but time will tell
Time to start stocking up on seafoam
They dont care
looks great hope its as bullet proof as the 6.0 gas is today
I wonder if they fixed the issues with the lifters seizing in their bores on this design. It's been a super common issue on the Gen V small block since it came out.
Guys the best information I could find so far would indicate that the new 6.6 Engine will have both port and direct injection that is what the article I read seemed to indicate. Right now I just say seemed to indicate.
With the variable oil pump it sounds like that it is going to fluctuate and possibly starve the engine of oil. It seems to new to perfect
High pressure fuel system, the first thing that takes a crap right out of warranty.
I’m interested to see the longevity of those injectors. Basically operating at the pressure of a diesel fuel system with no lubricants in the gasoline like you have in diesel. Look like a PITA to change too.
The high pressure pump fails far often then the injectors. The most common high pressure fuel pump failure is to leak fuel into the crankcase, many GM engines have already had that failure.
@Richard Skipper You mean very common!
The injectors tend to clog easily so they do fail more frequently than the injection pump. However this fuel system is well below the pressures of a DI diesel and these injectors are only a little more difficult to change than a traditional port injector. I'd like to see the addition of serviceable in-line fuel filter again personally, but this fuel system has been in place for some time now on GMs other vehicles.
@@robert91rs Diesel fuel is a good lubricant unlike gasoline.
@Richard Skipper GM has TSB's for several different engines related to leaking high pressure fuel pumps.
14858 is for 2014-2015 8 cyl. or 6 cyl. Tahoe, Suburban, Escalade, Silerado, Corvette, etc.
Ive read that with a teflon coating on the valves and a oil seperator built in to the intake with the recommended oil it greatly reduces carbon build up.
Watch Ram finally do a 440 HEMI.
I just ordered a 2021 Express van with the same engine. Can't wait to see how well it performs
I'm about to get one too, really nervous about buying the latest stuff though. Did that with my 08 Ford 6.4L diesel, bad mistake.
DI will be a huge issue with long idle times.
Why?
@@PurpleHeartVR actually a lot. unless the DI system and engine is completely designed for idle (which I doubt since any non- stationary engine is designed for wide rpm loads)
no heat is created to run the emission system efficiently, injectors and intake needs a lot of airflow to vaporize the fuel otherwise it will create more soot (diesel anyone) that's just few of the issues. DI engine operate very efficient and powerful under load but at idle they suck.
They engineered and specifically designed a new ventilation system for this engine that separates the oil from the air so the gas can recirculated without the oil, thus fixing the issue from carbon issues with some other DI engines.
they've been saying this for years that the PCV system is now fixed and yet we have the same issues. Engines aren't designed to idle for extend period of time
Benjamin Kessler “they have been saying that for years” news flash technology improves, must suck to fear monger about minor things
I would absolutely do the 6.6 gm or 7.3 Ford gas motor for a hd pickup, box truck, whatever. Diesels work great, WHEN THEY WORK. Cummings, Powerstroke, Duramax, ALL have their issues and GOOD LUCK getting that fixed after the warranty.
"Industry-leading torque" in the gasoline Super Duties for a few more minutes, yes.
True..Because of it's displacement and Not from any design/advancement. Chevy's 6.6L makes the most TQ/ displacement and the 6.4L Hemi makes the most HP/Displacement of the Big gas engines available in HD trucks.
Should also have port injection additionally, to direct injection, to minimize carbon buildup.
I just cant get over how much David Spade has changed
I can not believe GM no longer makes a standard cab version of their pick up trucks. I'll never be able to buy a new truck ever again now. I simply do not want , need or will buy an extended cab or a crew cab truck. I just dont want it.
They have not come out yet. I looked it up a few days ago
They introduced Direct Injection, did they also include Port Injection, to deal with carbon buildup. Ford uses dual port injection (they learned the hard way with earlier ecoboost engines which were only DI) or they use Port Fuel Injection as in the new 7.3 L. So, curious are they only using DI, or also PFI?
5.3 and 6.2 engines are having hudge problems with carbon.
Direct injection only is a major problem because of the pcv valve to meet emissions requirements carbon and dirt built up with be a big problem for this engine unless you install a catch can system on it to keep water and oil out of the intake system's air flow.
They engineered and specifically designed a new ventilation system for this engine that separates the oil from the air so the gas can recirculated without the oil, thus fixing the issue from carbon issues with some other DI engines.
@@zimks so they say. There IS no problem with port fuel injection in the first place!
How are they able to keep the valves clean with direct injection would have been a great question for him.
Pretty sure they fell short on the power ratings 😔
It would be nice if you would start making some cago work vans, a shitload of them would be nice because every 100 V6 engines I see maybe 5 V8. Which is a big pain in my ass because I won't buy anything other than that 6.6L V8 in my options are greatly reduced. I want an extended version with the 220 amp alternator and 770 cranking amps battery. But that's all stuff I'm going to probably have to additionally add on after the fact. Once I can finally find the one I want.
Do you get the chrome crankshaft and water pump pulleys?
I love how everyone is acting like GM just introduced DI... It's on every single LT, Gen V engine.
Curious if this engine has cylinder deactivation? Also wondering what the differences are between the 6.2 in the 1/2 ton and this motor.
I am looking forward to a truck with a 6 speed transmission again, my 8 speed hunts for gears and bangs too often.
Hopefully they will keep the auto stall feature out of this HD segment.
Based on the flat valley plate I'd say it does not have AFM
It does not have dod/afm/dfm whatever you want to call it. It is all 8 all the time! Issues with dfm
I'm a GM guy thru and thru... But that Ford big block is just so much more appealing, so much so I have my eye on a F350 once the power numbers come out
Interested in the reliability and consumer reviews of this new GM 6.6L gas motor VS Rams 6.4L gas motor.
Derrick Lavoie in reality, both bullet proof. As a mopar fan, hemi over that Generic Motor Crap boat anchor
Hemi valve trains are terrible.
benjaminwayneb are you referring to the Hemi “tick”?
@@frdmstnggt99 Lifter noise, lifter roller failure that takes out the camshaft and MDS (multi cylinder displacement) problems.
The valve trains are noisy when the engines are new and they only gets worse from there.
benjaminwayneb while I don’t doubt these problems I can’t help but wonder what generation of engine this is specific to. My 2015 1500 5.7 is quiet as a mouse. There are a few 6.4s at my work with over 100k miles that are just as quiet but they’re both 2014+ year models.
Very nice. New tech with some old school throw backs for durability and everyday reliability
Rip 6.0 Vortec 1999-2020
Rip vortec
I wonder why they dumped it and went to just the 6.6? Probably emissions reasons. Not everybody buying a 3/4ton truck needs 400 horsepower and a bunch of shit that is going to break. People would still buy the 6.0 if it was a cheaper option and as you said it's been around for 20 years.
0778drz110 I mean the 6.0 is a great engine but to be fair it was the weakest in terms of horsepower and torque in its class but was probably the most reliable but I think they should’ve brought back the 8100 and modernize the 6.0
2006 Silverado Z71 nope Vortec 1999-2013 ecotec vv Direct injection v8 is junk
Vortec was re designed In 2014 now called “ecotec”
The interviewer doesn't care, the interviewee doesn't care.... The audience doesn't care. What a show
Why do these truck manufacturers keep fluctuating their engine sizes? Back in the 1980s, their 3/4- and 1-ton pickups relied on 350 cubic-inch (5.7-liter) and 454 cid (7.4-liter) iron gasoline V8s. Then GM added an 8.1-liter V-8 alongside the 7.4. Then GM eliminated the 8.1 and eventually replaced the 5.7 and 6.0 with a 6.2. Now, GM is replacing the 6.2 with a 6.6. And Ford is coming out with a new 7.3 after years of offering their 6.2 as the only gas V8. Are they just playing with engine sizes for marketing purposes?
GM has been using the same 6.0 for the last 20 years in the heavy duty, same for the Duramax
Why not?
@@Icutmetal, the longer an engine is use, the more it proven itself to be reliable
I think the EPA regulations are ruining Diesels longevity. Their use to be a big spread on the fuel mileage between gas and diesel. Now not so much. Towing power will still be diesel for sure but I think the days of a diesel grocery getter are going to come to an end. Why pay the 10K difference if you don't need it?
Their replacing the 6.0 not the 6.2
I'm calling the 6.0 makes a victorious return in 2021
@Richard Skipper your probably right but the 6.0 is a proven engine and although it is a little weak the engine runs forever and usually out lasts the body Im interested to see if the 6.6 lasts as long as the 6.0 for turboing the 6.0 it's just little pipe dream lol
Love to see the comparison to the new Ford 7.3 for MPG in different loads.
And this extreme long, nice intake could be very good for torque at low rpm.
I would convert both engines to LPG for more economy and less carbon emissions.
His ending comment did not convince me it's a robust design engine. I'm pretty confident and I'm pretty sure are not words engineers should be using. Lmao
Now if they could just design a decent looking truck for this engine it would be a win win.
311hitwall Never heard of such a thing, but it sure sounds like a bad idea.
I hate that front.. that is ugly.
Already put my order in for a 2021 silverado 2500 crew cab long bed 2wd WT with package and some extra accessories. Hell, I already bought rims for it, waiting on the tires.
Here comes the high school shop class graduates thinking they are smarter then engineers
Yep lol
zimks
Well, some of the kids bring common sense.
Super smart people lack this ....
@@NoharaLoco-gw8ld I was more speaking on the fan boy stuff, but when it comes to 6.0 engineers had to figure out a way to pass emission testing. The only reason the shop guys "fixed" the 6.0 was because the only standards they needed to pass were making the engine run.They simply took off all the sh!t needed to pass those test. Do you think engineers would have EGR in a vehicle if they weren't forced to have it? No!
(I know there are other issues with the overall engine but that is definitely one of the main reasons)
We want more 6.6 gas videos!!
Meanwhile, Ford has a V6 that produces more horsepower, more torque, and better gas mileage. I expected more from GM based upon competition in the market.
The Ford 3.5 v6s do make great power however the coyote gets more mpgs towing. Boost requires more fuel that's why Ford won't put the 3.5 in a 3/4 ton.
More horsepower, more torque, better mileage but less RELIABILITY. keep your ecoboom, it won't tow anything when its broke down in the shop and you're in your Ford focus rental
scot miller this is for 3/4 and 1 tons my dude
@@blakeok952 I know that op was bragging about ecoboost. If they were so efficient Ford would put them in 3/4 ton trucks
Lol, meanwhile Ford ia still developing engines that will pass the 100k mile mark without breaking down.
Hmm what's the irony the old 400 SBC has siamese cylinder walls and this new 400 SBC has siamese cylinder walls. Let hope cooling isn't an issue in the new one.
It's still not a big block and it will not pull like a big block
@CurlyHeaded baby you sure don't know shit. The 8.1 is a big block in 2003? I have a 1999 3500 dually 4x4 with a vortec 454 in it? Last big block 1990 ?????
@CurlyHeaded baby 454 will out pull the ls engines you know why weight and traction wins tug a wars
@CurlyHeaded baby hey dumbass idiot you still think my 1999 Chevy 3500 has a vortec 454 small block in it? Cause the last big block was in 1990 remember idiot?
@CurlyHeaded baby curleyheaded dumbass idiot is more like it
@@thestig8768 tug of war meens nothing and proves nothing. Hook a trailer up and tow it down the road that tells the story not stupid tug of war. Tug of war is for idiots who like to break stuff and prove nothing. It's a stupid kid thing
Beautiful factory.
Am for real what point of this 6.6L V8 when 6.2 have the same hp but higher torque
@JJAJFOREVER more durable ok i see
The power band is shifted to low end torque. You aren't supposed to be winning drag races with this truck, you need a less stressed engine means a longer lasting engine.
12krinson 6.2 runs 11.5 compression and needs premium $.40-$1.00 per gallon, so take this motor its detuned and lower compression 10.8 for more reliability and not having to run premium.
Longevity
With just direct injection how are they planning on taking care of deposits on the back of the intake valves?
Looks like another GM engine that will get swapped into Fords in the future.
Ohhhh, that's some fine burning right there. 👌😂
not really the new ford engine is bigger and also pushrod so actually ppl will swap the 7.3 into their chevys :)
@@juicebox8549 😂 u know ppl are going 2 but this small block into fords. 😂
@Steve Paige how is that a win? 😂
@Steve Paige must be or they are?
How do you clean the valves of carbon? Do you really think the "perfect mixture" will not build up carbon?
It’s called sea foam.
It's not a big block, therefore it's not gonna be bought by me. 454/496 FO LIFE!
Should be 496,
Good ol vortec 8100
😊
Good luck with your garbage ass 0-60 and shitty mileage. Yeah your big 454 is good for 0-35 first gear then second gear it falls on its face with it's 4500 redline.
This new engine has much shorter gears, better gas mileage, 6k redline.
you will see soon when everyone switches to a small displacement v8 with twin turbos or bi turbo and see it puts out plenty more torque than your big beefy 454 with a garbage 3 speed.
@@PurpleHeartVR yes but a 454 can be fixed in the backyard with hand tools. You know, things break down when you try to keep them for 30 years.
What I wanted to hear is what they are doing to eliminate or greatly reduce carbon build up on the intake valves with the direct injection.
I am a GM guy, my dad worked there and all I own are GM vehicles. I want a 2500 as my next vehicle, but I WILL NOT allow myself to buy something with DGI, and this makes me so sad because all I wanted was a 2500HD and now i have to go look at the Ford F250 with that 7.3L with the Port Injection system.
Still prefer diesel.
So this 6.6l make 4 more torque and 19 less HP than the 6.2?
And don’t deactivate cylinders & shut off at the stop light. YooHoo!
The ford 7.3 is going to eat this thing
😂 It’s a big block so I sure hope it does
This is gonna be nasty with a ls Intake cam and some boost
Junk
Today’s engines are great. 99 Silverado with 300,000 miles on it. Only parts were normal brakes oil rotors tires except for a alternator at 214,000. That’s it.. Runs great uses no oil and no leaks. The bad. Wisconsin rust belt! The body is shot and brake-lines I don’t trust.
I use it on the farm only because of this. The prices they are demanding now. Wow! They could do better on the body’s . I mean all brands. I also have a 2006 L B Z from Alabama. It’s body is 100% rust free. Looks like new yet.
GM= RECALL KINGS
Ford = let our loyal customers fix it.
Ford Already Having To Recall New Ranger
@Gary Dingleberry, I'm on my third vehicle that was built around that time, I never had a problem with the ignition, I've lost a 4t65 in one and timing chain in the other
Ford literally recalled 1.5 million vehicles today LOL
@Gary Dingleberry Ford literally has biggest recall of a single automotive company in history........21 million...
WHAT A CHANGE IN THE HD TRUCK WORLD. EVERYONE SWITCHING TO GAS ENGINE NOW.
small block no thanks. I will have the 7.3 big block all day long over this.
Just wait till Democrats take over again and gas 4.00$ a gallon you will be mowing around that big block
ill stick with my 454 big block which still pulls like a beast
This guys name should be Stumble Monster Jr... Damn GM That variable Oil pump and that Direct injection is gonna get us big time oh boy ....
Ford's 7.3L V8 is better than it
Ford’s engine is like an actual big block version of an LS. Kinda like a big block 7.3 version of the Vortec 6.0 from what I’ve seen. I like the way Ford is going about this.
So the 6.2 is 420hp and 460 torque. So please explain to me why this engine, the 6.6 is better in the heavy duty? I'm not getting it.
All I know is Fords 7.3L V8 is more badass.
@I know you are right, And I just got owned but: that made no sense at all lol
@@Jimmyxsx so true
@@juicebox8549 He's just really scared.
But you don't know shit so who cares what you think Ford idiot
@@juicebox8549 your just a stupid Ford idiot who don't know any better.only dumb fucks drive junk fords
I hope this one is as durable as 6.0 it was one tough ass engine
Looks kinda like a gen 5 lt1, just with a truck intake
Ford 7.3 is better anything better than what Gm makes 😂😂
They just didn't want to call it a 7.4 like the older 453 Chevy lol
Anderson Rodriguez we’ll see buddy
Ford lovers always apologizing and defensive.
Just joking around guys 😂😂 relax
yet they looked and the size and reliablity of the GM cam in blcok 6.0 to make the 7.3. Your welcome
This gone be be swapped into so many cars with that forged crank if they make a crate version, which would be smart for gm to do
Chevy still sucks,
John Luevano jr. like your mom
Still? Always have
yip yap or your dad?
Ive always been a fan of the Chevy 400 small block but I got to say the numbers aren’t as exciting as I had hoped. 401 hp and 464 Torque coming in at 4000 rpms . Right now my magnum V 10 has 310 hp and 450 torque but it all comes in at 2400 rpms . So your not having to totally wind it up to get all it’s power. Honestly I can’t wait to see what the new ford 7.3 liter numbers come in at.
If the engine loves to rev, it is not as bad as it sounds. That old gm 6.0 in my company-owned dually (utility bed, crane, 14k pound gross weight) is happy to rev all day long, day after day. 6 years in and 140k very hard, back road miles, it's still going strong. Im so impressed I'm getting on of my own (2500 single wheel crew cab). Yeah, that 6.0 is dead, but this one has more power, and hopefully it loves to rev like the old one.
I do agree with you though, low down torque can be intoxicating.
