After General Motors announced plans to eliminate tailpipe emissions by 2035, the gearhead world was left wondering if the current 5th-generation LT-series engines were the last in the legendary GM/Chevy small block V8 engine lineage.
But according to a press release late last week, it looks like the General is giving its small block V8 at least one more go-around with a new 6th generation.
Though precise details on this new “small block V8” engine were scarce in the release, one number did stand out:
<Dr. Evil Voice>
854. Million. Dollars.
</Dr. Evil Voice>
That’s how much capital General Motors is investing into its manufacturing facilities to produce components for this new powerplant. GM says that money will go towards four main plants: Flint Engine Operations in Flint, MI; Bay City GPS in Bay City, MI; Defiance Operations in Defiance, OH; and Rochester Operations in Rochester, NY.
The news in the release was primarily centered around GM’s investment plans for this new V8, yet there are plenty of references to the General’s plans for electric vehicles too. Specifically, eight million dollars going to Defiance Operations for developing castings for its “future EV strategies” and 56 million dollars sent towards Rochester Operations for making battery pack cooling lines.
General Motors says these new 6th-gen. V8s are destined for its full size pickup trucks and SUVs, with no mention of the Corvette—which is particularly interesting after news of the new Corvette E-Ray hybrid recently trickled out.
Still, one has to wonder if this new small block V8 will share much with the LT and LS series engines that preceded it. The performance, reliability, and popularity of these engine families in both OE and swap applications has been a boon to the hotrodding community, so we’d be surprised if GM deviated much from that LS/LT recipe.

Good for you and for us, Thank you GM/Chevy!
From what I have seen, GM needs to quit putting in this junk they use for engine parts and put something of quality in there. Rocker arms and lifters that go out with 5,000 miles on vehicle??? WT#
5 another hater that knows nothing at all about engines must be a Ford owner
Think he is dead on have blown three of those up. But with all the Fords I have never heard a motor yet
Engines require oil.
And that oil does not last 7000 miles
Because no body wants to talk about there ford’s on internet they will get sculleded you have to practically strip your whole ford to get the engine out CHEVYS WILL ALWAY BE BETTER
U have to put the new oil back in after draining the old stuff out.
The only thing Chevy ever made worth having was Vans since 1972
Love my ’02 Astro w/ that marvelous 4.3 litre V6. Best motor GM ever made. Not much hp or gas milage, but great torque. And bulletproof.
just cause you don’t like em you say they are junk…, I’m not trying to piss you off but, thats only your ‘opinion’, I’ve had some damn good Chevy’s over the years, they all were outstanding, my old Silverado pickup truck with the 5.7 liter 350, throttle body fuel injection has 300,000 ‘HARD’ Miles, & it was a work truck before i got it, & i can tell that they did much Heavy towing with it cause of the Trailer brakes on it, & the bad dents they left on the inside of the bed, they hauled some Heavy loads in it, & it still has alot of power, & the 4 whell drive still works perfectly in high & low range, i agree that the new model V-8’s Suck, but all the ones up until 2,010 were great, I’ve had 305’s & 350 Small Blocks, & 400 Small blocks all were ‘Exelent’ engines, powerful, tough, long lasting,& low maintenance, But Chevy Fucked us on the new 2000 model motors, & they won’t stand behind the newer ones, or make good on fixing them, this is Unexceptable, they dropped the ball on modern new Chevys, but don’t kick the old good ones, it’s a Hypocritical text U made, don’t take it personal…but it’s the truth….dig it
’96astro 237000 mile burns no oil starts every time luv it
I work for gm he is no hater the lifters fail so do the keepers and the injectors how about the 4.3 liters chain rubs threw oil pump not to mention the oil leaks brand new corvettes blowing engines with 50 miles I can keep going mabe u need to educate yourself first
I bought my first new vehicle in 05 a GMC 1500 with 5.3 only problem so far was oil pump at 180000 miles. It now has over 200000 and runs great gets as high as 23 mpg averages 19mpg. It still hasn’t replaced my first truck a 1950 GMC sill going strong bought it in 1964. Keep them serviced and they last.
I’ve had my S10 Extreme since 2000 I have 400,000 miles on it and it’s never failed me once still runs like new love this motor and little truck
Don’t smoke so much!
This is accurate. While automotive “hobbyists” prefer the larger GM powerplants, they also have the skills, the time and the money to address persistent, early failures in the engine. Millions of everyday drivers do not and have shown little apprehension about moving to manufacturers they perceive to be more dependable.
I don’t know what you people are talking about. I have almost 300k miles on my LS and have only done regular maintenance on it.
Your one of the lucky ones iv put a cam lifters and a transmission in my 2016 silverado at 95000.. and cam and lifters in my 6.2 2011 camaro at 72000
I have a 2008 Silverado 1500 Lt 5.3 with 250,000 miles regular maintenance , got new radiator, starter and throttle body are the only things that have went bad. That’s been in last 50,000 miles.replaced with ACDELCO.i love my truck.
Mine is at 378,000;-) 6.0 2000 Silverado #1
-also big time oil useage that the dealers say is normal. Thin piston rings & low ring tension.
My 2000 GMC Sierra has 340,000 miles, regular maintenance and only new engine gaskets and water pump replacement, all else is original. Transmission replaced with factory rebuilt unit at 296,000 miles, nothing wrong with old transmission just part of my preventive maintenance. Love this truck.
The LS motors are great have had a couple with 250 to 300k miles the lifters In my farm truck just started ticking now with around 270k on strictly a farm truck drain oil on them and take care of them they will treat you good.. my 19 6.2 Chevy has 95k on and going strong
The barn doors! !
1999 GMC 5.3 With 250k miles.
The only part replaced is the fuel pressure regulator.
I’m on number 3 last one lifters went out at 40k miles . Junk junk junk
My 2008 2500hd 4×4 has 375,000 on it with out a click. Dellow 400 oil every 4000 miles. You have to run the right oil and change it once in a while.
They are not building it for. They are building for me and I love it . Thanks GM
Wow that was not only a stretch but shows you ignorance. The LS has been an extreamly reliable & easy platform to upgrade or swap into almost anything. You don’t get that kind of a reputation for doing poorly. Granted there are a few exceptions to this rule but alot has to do with people not changing their oil or using the wrong oil. The 0ring gets hard on the oil pickup tube as it ages but easy to fix every 150k or if it’s been overheated. Wish people would think & check facts before making snide comments. What exactly have you ever accomplished in your life if we may ask? Can’t be a whole lot… please state facts that can be verified by others & not your mom or relatives. PS you shouldn’t be driving a chevy anyways, your attitude fits a guy driving something to fit your statis in life…
A bicycle perhaps, but don’t forget they take maintenance too!
Well I hope all you Chevy fans know that GM is now owned by a Chinese company! Fact look it up !!
Good for you Yahoo,go for it.
G.m kept up the good work just like to say i love my 2023 zl1 Camaro it rocks
Long live the DODGE HEMI they own the performance world. The TRX will destroy the limp RAPTOR R. I own a RAM with a worked 5.7/ 345 HEMI. I have both Ford and GM performance engines the LS6 ZO6 is one. The FORD 5.0 COYOTE MUSTANG GT. The HEMI’S ROCK. GIMME A TRX AGAINST any truck!
My friend have a 5.7 hemi truck oops had until he met my 6.2 Sierra. Engine blew up at 105mph trying to keep up. GM trucks or nothing at all. Oh I pulled it to the shop for him. LMAO
Not according to factory stock at nhra. The mopars always finish last. Just saying!!!
I need to bring bag and it’s like a 454 you need to aim at my age group I like to go fast enough power pedal
I have had 3 chevy trucks. 1969 suburban – 350/350 637k miles 22 years 1 replacement engine, 1 replacement front end, 1 rear end. And next – a 1994 K10 standard cab, shortbed, step-side 350 TBI/700R4 205k miles and NO SHOP REPAIRS !!!! AND still going strong. And a 1999 4,3 blazer 4×4 LT – 21 years, 225k miles, 1 trans at 220k miles, and still going. So – what’s the problem- Chevy all the way. I did hear that chevy turned the rear end “made in Mexico” somewhere around 2000, and they are trash!
I would just like to say thank you to GM for keeping a small block
DID YOU TEST IT LIKE THE NORTH STAR?
Nice jab. Lol. When Ford put the Coyote out GM got caught sleeping. The 1.87 hp per cubic in vs the LS at about a half hp less I think is still burning that ass. But the new Z06 with 680hp + na. Is nothing but a big Coyote. Then Ford came out with the Godzilla 7.3 and its a 435ci LS. So go figure. And bless their hearts they each paid half to get the 10spd auto developed. Good for everyone. They finally get their heads out of the poopers and now we go electric. God save the gas engine the Queen is gone.
Very well articulated. Hoping its not another push rod with cylinder deactivation
Ed foster. Wimberley Texas
Gas will be around for sometime in the future. Batteries do what batteries do. Power density is not even close. Infrastructure to support EV’s
cannot support anything but commuter trips with any confidence.
Hey that sounds great!!!! We will enjoy this new motor 1 last go round.
The next generation of the small block will finance the development of future EVs. Let the market drive this EV development.
I hope its a 4 over head cam v8 that is better then the new 5.5 liter corvette flat plan crank
I think the gev 5 engine should have access to the lifters without removing the cylinder heads and the engine block would have a center section that bolts the two sides of the block together to keep it ridged like the LS and Lt blocks but it could be removed to access the lifters and I’m not sure that the oil pump should be positioned in the front of the block as it goes against the force of Motion when car is moving! The first Gen v 8 had the best oiling system ever and never gave problems because the pump was always submerged in oil and didn’t have to pump from the rear through a long pickup tube and the barbell system is not a great idea and should be redesigned but never use a different bell housing design that keeps it a C H EV Y !!
This new motors should he a free replacement to the current generation that are nothing but headaches of problems
ABSOLUTELY RIGHT, Dan!
The new oil pan and bolt to change the oil is ridiculous, you remove that plastic bolt and the oil just comes flying out mess every where, need to go back to old design.
What an idiot move , EVs are taking over, GM is buried in debt and they waste their money on a V8. , lol
Jimmy boy, you’re the real liberal thinkin “ev” biden voter!
Evs taking over??? Taking over what???
Where are you going to plug in your EVif you live on the 5th floor of your apartment
I’m a multi linguistic kinda guy and I’ve read this comment three times but I still fail to comprehend the meat and potatoes of the direction.
EV will absolutely NEVER WORK! Unless you can make them charge themselves
I believe they can recharge them.If it has wheels that turn they can recharge themselves.They just don’t want to.The oil company’s are not gonna be cut out of this deal.They are the ones taking over the fee’s for charging They are not gonna roll over and lose all there trillions in selling us gas
We drive a Bolt EV. Put 36k miles on it. Love it. We charge at home. Yea range can be a issue since we can only go 200 or so miles on a charge, but how often do most people really do that? Charging at home it only cost us $0.03 a mile to drive it. Virtually no maintenance either. BTW we don’t give a $h1t about global warming BS. Bought it because we like it and it works for us.
Oh and we have a 2000 silverado with a 6.0 in it. Good engine but only gets 10mpg.
EV is no more than the Diesel fiasco bureaucracy and conspiracy once promoted in the 90s. As always, bureaucratic and corrupted politicians and big money CEOs are the ultimate winners and we the normal class citizens are the victims that are losing our hard earned money to them. If a storm knocks out your house power for a few days, are you going to wait for your $30k or $100k Rivian EV in the neighborhood market EV stall for 5 hours……. haha, amusing or misery!? Bicycle to work? Bus? Whatever, a piece of useless junk that has just cost your second biggest purchase in your life! Hmmm, where is the common sense!? Saving the planet is a noble cause, but doing it in a senseless and irrational way just utterly has destroyed the purpose! It has not even touched the topic of manufacturing the EV, mining the minerals, and generating the electricity are far more than “green”! Wake up, fellow citizens, there are better ways than EVs, at least, don’t be foolishly putting all eggs in a basket!!! Our humanity and world are at stake, tread lightly, most importantly, wisely!
Who cares, make sure it’s powerful, fast and last long
Rite Gary’s rite
At that investment, CHEVROLET no longer means, Cheap, Hardly Efficient, Virtually Runs On Luck Every Time!
450hp. / 520ft. lbs. torque
17 – 20 highway mpg. Would be nice in a new 3500 HD
I may buy a Chevy now that they are copied after there big daddy Ford
This is a real surprise since Mary Barra is on a mission to completely electrify the entire GM fleet by 2035. Where is Mary’s input on this new ICE strategy GM seems to be embracing now? In fact, where is Mary? It seems the last appearance we have seen from her was on December 8, 2022. Is there something going on behind the scenes at the Ren Cen?
Just stop all this electric car bull$#!t and bring back Pontiac GTO….
Just bringing back Pontiac Division would be wonderful!!
Problem with GM is there is no more Oldsmobile!
Man are right
Yes please do
10-4 on the GTO
I don’t believe that GM would invest that much capital in an internal combustion engine program if there were plans to do away with them anytime in the foreseeable future. Personally, I believe electric vehicles should be available to purchase for those who want them, but also shouldn’t forced upon those that don’t.
That sir, is the most common sense comment of ALL!
1990 ZR-1 LT5, the forgotten 7 world record holding engine. Still King Of The Hill. Waiting on someone, anyone to break the C4 LT5 records. GM was double overhead cam V8 way before anyone else. Several manufacturers have tried and all have failed to break those records, including Ford, so take you coyotes and shove em. I also own a 2015 Silverado 1500 6.2 ltz with AFM delete. It’s a beast, looking forward to the 6th gen, going to be badass.
Too bad the LT5 was designed by Lotus and manufactured by Kekeifer Marine (Mercury Marine).
Ford Double Overhead Cam Indy V-8 …
255 cubic inch V-8,naturally aspirated from 1964 to 1968,was turbo-charged in 1969.
This engine won at Indy in 1965-1966-1967 and the turbo-charged engine won in 1969-1970-1971-1977. The turbocharged Ford V-8 was only 161 cubic inch displacement do to the rule limit on displacement.
It was the first motor to be put the GT40 engine bay…
Maybe they have plans to burn hydrogen for fuel! Now that would be really a Smart idea
May as well throw a billion at the horse & buggy. This truly is more American waste born out of a testosterone/steroid laden society. It’s sad if ya think about it.
Yes. My father in law whom had long passed alway worked for ge. Made the first man made diamond and help design today jet engines said for years hydrogen is the only way to go
In the early 90s I wrote one University English class paper about what would be the future of automobile, hydrogen, electric, or natural gas. The conclusion of my paper, hydrogen!
I had a 2010 equinox the motor leaked so much out that I had to get rid of it tail pipe came off going to Florida it was due to oil leaks my drive yay looked like I parked and changed oil every time I parked it so well its gone and chevy grange sail that it needed mains replaced but it didn’t work big polluter
Chevy will always be number one and let’s open our oil fields now!!!
Chevy/ gmcs are the most beautiful badass vehicles ever built I have a 2018 gmc sierra denali!!!the 4.8 the 5.3 and the 6.0 6.2 engines will always be my favorites. I here people crying about how these engines are crap its all in how you take care of them the afm system can be deleted with a 200 dollar range device and problem solved that’s the only issue they really have lifters weren’t meant too be turned on and off.thats the first thing I did when I bought mine with 25k miles.i had a tahoe before this great vehicle traded it in with 450k miles original engine and trans and still ran like new.fords are junk with the ragged 6.0 6.4 6.7 diesels and that ragged 5.0 gas engine that burns oil and sounds like a diesel at 8k miles I’ve worked for a Ford dealership you wouldnt believe some of the crap i saw go wrong with those engines fords are just low quality junk i would never own a Ford!!! I can’t wait too see what gm has coming out next.
GM general made crap Ray Chevys are junk buy American buy a Toyota !
My 07 Silverado 4.8 non AFM had a lifter go bad and ate the cam at 95,000 miles. Full synthetic Mobil 1 every 5,000 miles and meticulously maintained and garage kept. Repaired by former Chevrolet dealer mechanic who said he had seen many of these problems because GM uses shit lifters period. Traded Crap-erado in on new Ram and haven’t looked back.
I’ve put 200K on two Dodge Ram trucks. I change engine, transmission, and differential fluids religiously. Very few repairs, mainly wheel bearings. EVs not viable, that’s why they have to be subsidized by the government.
Good luck with the hemi. They crap out to from simple idling!
By the time we are established with EV’s and have an ample pwr supply hydrogen will no longer be in theory but in use. Because it can run clean and cheap (water) what will be the power base then?
I had a 91 zr1 with the lt5 engine. Greatest ever. Even bought a brand new one just in case the old one failed. Now I have the 2012 zr1. Anyone need a new lt5?
Gas cars are awesome and they will always be around,electric cars are a fad a toy and they’ll fade out. We don’t have the infrastructure to make all vehicles electric and how’s that going to be better for the environment? Gas engines burn very efficiently now and it still takes a lot of junk to make electricity and batteries. just saying
If you think EVS are clean talk to all the poor animals that are misplaced by the strip mining in evolved making them
I’m engine builder, and wonder where power to produce electricity, will be generated. Suppose wind turbines will be used and a power developed for every charging location? The logic of tearing down established production/ supply of gas, and then watch oil companies struggle to find new ways to sell oil products, or go out of business, does not make sense. I am not ready to have prices of oil products rise, are you? Tree hugger, I am not, neither a gun advocate. Let’s not try to kill existing suppliers, to say this is progress!!
But general motors has failed to tell people about their truck problems on top of their Corvette problems how can you even sell cars that you don’t even have all the chips for it’s a liability
I own a 1996 TAHOE,265.000 miles,some motor only maintenace,well,water pump and as alternator those things,included my 2003 sub.never change,sparkplugs,and both running,like new ,i,have none complaints to the Chevrolet,
I have owned several LS 5.3 225k to325k elimanated all filters in fuel syztem except the one in the fuel pump cup disabled evap portion of syztem can run a 50/50 mix of 92 octain and filtered burt motor oil , peanut oil, fryalator oil, tranny fluid, basically any petroleum distilliate, its probally taking 85 to 95 hp away runs perfect 55 to 65 mph to thousands of job sites or throw 96 octane for the weekend with new plug gap turn cold air inducton and adjust progamer a tad and blow doughnuts in parking lot with quick 0-60 pace that speeding tickets arrive faster thAN A MAN OR WOMAN WOULD LIKE! Runs 40 octane smooth and does job or 96 octane plug gap change , one switch wired forced cold , program tweek maybe 10 min. I have turned all of them excessively in the rpm department 5.3 will run forever! The 5.7 vortec were even better but 160k175k was end of line! 100 percent 5.3 ls is best all round versital sm block gm power or powerless however u chose to adjust ur company employee ride to jobsite n back power or personal powerhouse tuned to the foot operating the throttle feather, i run a size 10 redwing steeltoe boot so the downpressure is little aggresive for most but there only a few of what in my day we where gifted wheel men run the edge dropped 2 wheels over and rode the rail to perfection, the only down side those ugly blue flashing lights but always a real,ride,rush every ride by my hands! 5 employees hands the been brakes n tires and free rides to job sites 40 percent money in the bank of every job site to n froe the 5 co. Trucks in 7 yrs have earned my company roughly 600k profit with less than 12k invested in all five ! Lets see a oval around a blue thing they call or i call the problem! For those who didnt understAnd ford circled the problem the blue oval says it all! Oh thank heaven for like a rock tough as steel bow tie of king of every mountain and every valley of our old USA! Now lets see what usa means in the next 50 years? Future looks bad im staying here i got what god intended any of us to need or have ! Good luck z gen u are the last and thats fact, stevie wonder can see that! What a ride though no complaints cant wait for my re-do lol
2035 or 2040 to eliminate EV?! Really!? That’s only 13 to 18 years away! That’s insanely arrogant and ignorant, if not foolish! Besides all the obstacles people are taking about, infrastructures, power grid, battery degradation, time to charge, etc, etc, just one more common logic, battery, especially lithium battery, does not like cold, hot, and water. Hence, this basically limits geographically to dry and moderate climates near the equator, so it puts the equator, north hemisphere and south hemisphere, and any hurricane and floody climate zones in between out of ideal lithium battery operating condition. Hmmm, if the ICE is banned, hundreds of millions people live in those extreme hot, cold, or easily flood weather geographic ares are out of luck for a reliable EV! Sorry people, you are going to have to count on your feet, bicycle, bus or other means reliably to move around! Not liking cold, hot or water are natural chemical properties.
Could we successfully change them or overcome them? At what cost even if we could? Or, are we able to change all the different natural earth climate zones to one that’s ideal for EV battery to operate in!? At what cost, even if we can, tilt the earth axis, move the earth closer or further away the sun, manipulate the weather!? What about environmental, animal or agricultural consequences?! I think we all know the answer! EV is NOT the “future”. EV is no more than an option, one of the our alternatives only, yet the jury is out and far if it’s a viable or good alternative, let alone mineral mining, producing EVs, batteries, and electricity are very environmental damaging and polluting process! They don’t just come out of thin air, and EVs are costing pretty pennies, equal to if not far more than a ICE contemporary!
I meant 2035 to 2040 to eliminate ICE
I would think a V-6 Engine, would make more sense, even if it was turbo charged. EV vehicle still ate not fully ready for prime time.
I hope they pulled their heads out of their asses and designed it back to where you can service lifters without pulling the heads off. What an absolutely stupid design that is!
Been racing outlaw cars for 36 years out of 20 cars 18 will be chevys should tell ya something. Got a brain or not….
