All I can say is that my C8 LT2 is an absolute dream ... I have the performance exhaust as well. Much to the chagrin of my neighbors ... Cold start will wake the dead. But oh man, when you tickle to go pedal it's a symphony.
This video kind of made me nostalgic for the days I was an engineer for GM Powertrain. 10 years ago I was doing Lube and Vent testing on the Gen 5 prototypes, and I never would have imagined it was going to lead up to this.
Totally agree! The sky is the limit and she will always be a great bang for the buck. Ah...no pun intended. Z06 ZR1 maybe a Zora or a mild hybrid/motor combo.
This could crush the industry in all types of ways. That's the most exciting part about this c8. From the little sport compacts to the high and mighty supercars. We're looking at insanely inflated prices on brand new cars. GM listened and delivered big time. I hope this does damage on the streets and hopefully other manufacturers will reciprocate. Shame on Toyota, and shame on Ford. Shame on Chrysler/Dodge out of all.
yeah, my ls2 gained over 100 horsepower from cam, intake and headers. Cant wait to see what a fucking beast like this could pump out while staying NA, or even with a supercharger right there under the rear window

The LT2 is just a slightly modified dry sump LT1 with a cam, headers, and intake manifold. It uses the same internals, same throttle body, same fuel system, and still isn't dual injected for carbon buildup.
Ya the only problem with the dual injection set up is that it is patented technology. Right now Ford is being sued for stealing that tech. In time they will release that tech. but for now just dump some fuel system cleaner in every other oil change.
@@jakebro5557 Lexus ISF and IS350 have been dual injected since 08. Nissan used due injection over seas. Porsche uses it in the 9A1 & Cayanne/Panamara. The Lambo/R8 V10 is dual injection. The EA888 overseas is dual injected in everything. Toyota even uses it in the Corolla, FRS, and Camry now. The BRZ, WRX, and Ascent are all Subaru dual injection. I believe the turbo engines non-STI all use it.
I hear from people in BGKY. That there’s a 5.5 liter version of the Blackwing LTA that’s getting dropped in for the Zora (2020’s ZR1) The engine features the following highlight characteristics: Twin-scroll turbochargers Electronic wastegate control Twin water-to-air charge coolers Twin throttle bodies Direct injection Dual-independent camshaft phasing Active Fuel Management / Cylinder Deactivation Variable-pressure oiling system Stop/start technology 1,000HP AWD with a 10 speed DCT.

Lt2 is not replacing the lt1. The lt2 is like the ls4 on front wheel drive vehicles. The bell housing bolt pattern for the transmission are different from the front location lt1, lt4, lt5 and truck engines.
Why would you need to change out coil packs? Hell I never had an issue with any of mine on the LS motors and thats after going over 200k miles in some of them.
As usual, Chevy`s engine R&D team is hitting a home run with this new engine. Even though it`s quite healthy, HP-wise, even in base form, those forged internals and dry sump setup show they`re building a strong foundation for even more prodigious output.
Penny Lane, allow me to share with you where i was going with this. Lexus LFA has a 4.8 liter V10. A V10 thats smaller than a traditional V8 AND lighter than a V6. This “4.8 liter” pumps out 560ps which works out to 116hp per liter. Acura Integra Type R with its B18C5 engine pumps out 200ps, thats 111.11 hp per liter. Their S2000 makes 240 with its 2.2 liter, thats 109.1 hp per liter. Are you starting to see the picture? Yes, despite having more hp per liter doesnt mean itll beat it. It just goes to show the amount of engineering that was put into those motors is nothing compared to what any big american V8s or V10s and inline 4s put out- in natural aspirated form of course. Im saying, regardless of how big American muscle goes, the engineering on their engines is mediocre compared to other car manufacturers.
Doesn't really matter if the end result weighs the same or more, and has less torque lower in the rev range because of a lack of displacement. Forcing you to go with deeper gears in the axle to compensate for having less torque down low. Lighter than what V6? GMC had a V6 that was over 470ci, probably weighed the same as a chevrolet big block,smaller than what V8? You can have an LS block engine under the hood and have no idea if it displaces 293ci or 414ci with no descernible difference in physical engine size. You can have a V8 smaller in displacement and physical size than a 4 cylinder. I think I recall honda or nissan having a 1.6 litre V16, and Henry Ford built a car with an 18.9 liter 4 cylinder.There's no traditional sizes, it's not a very impressive feat of engineering if you have a high level of hp per ci, but to get there means the vehicle has to be saddle with extra weight on and to be made a larger size,kind of seems to defeat the purpose. If you had to choose between 2 engines, both weighed 475 lbs, both make 500 hp, but one is 300ci and the other is 400ci which would you choose? If you had any logic you would pick the 400ci. Why? It's because you would have more torque which means more hp down lower in the rpm. Which means you're not having to gear it as deep, which means you'll get better gas mileage. If it's not giving anything up to the 300 ci engine in terms of peak horsepower, engine weight, possible physical size, but makes more power down low and same power at their peaks, then what honestly does hp/ci matter? If 4.8 meant 480 lbs and 7.0 meant 700 lbs then ok, but it never did. If both weigh the same then what's the advantage in having less displacement? Better engineering? How about wasting brain power on something that has a simple solution? 2009 Honda S2000 curb weight 2,850 lbs 2.2 engine 237 hp 107.7 hp/liter mpg 18 city/25 highway 2018 Chevrolet Corvette curb weight 3,450 (600 lbs heavier) 6.2 engine (2.8 times more displacement) 455 hp (1.9 times the power) mpg 16 city/25 highway With all the differences shouldn't the Corvette be a lot worse in mpg? It's because the lack of torque in the S2000 forces the need for a 4.1 axle where the Corvette axle is either a 2.41 or a 2.73. Even Honda realized they messed up and added more displacement so the peak torque would come in about 700 rpm sooner.
@@MrJimbo666 , hey fanboy, it's not MY opinion. It IS fact, out of 6.2 liters, this is ONLY putting out 79.8HP. Ok I'll round it up, 80hp per liter. Weak, if you ask me, bro. Big V8, Cuz Murica!!! That's why
495 horsepower would make for an awesome speedboat engine- which is nothing new for Corvette's engine! But now it's going to be smaller, less weight and more fuel efficient than the traditional big block Chevrolet engine!
Lt5 from the 90s was handbuilt by Mercury marine, who then proceeded to make an lt5 powered boat, towed by an lt5 powered Corvette. It was a funny and amazing thing to see.
LT2 is a great update to a very reliable Corvette Engine. How well will this improved engine with 11 to 1 handle 91 octane fuel when it needs 93 for proper performance?
Companies who usually race Corvettes had a definite say in the engineering of this beauty. Especially IMSA and Le Mans series. Sorry don't know which company competes with the R series Vettes.
my stage 3 (downpipe and injectors tune only old EJ motor) 2015 Sti w eurothane driveline mounts and springs/big rubber will out run and outhandle a new zupra w my kids in tha back lol. And its nothing near what my old Evo could do.. New cars hype machine. Kids need to get off the supra titty new one and the old 90s one that was same as a Lexus SC300 lol
@@carlocesari1 Who said anything about previous generation Supra? I'm talking about the new Supra.. With the BMW engine, and interior as well. The new Corvette is faster, nicer, and overall a better package..
All I can think of saying is"wow" and totally awesome dude LoL I'm Peter from Hamilton Ontario Canada and 47 years old and always wanted a Vette but can never afford one but it doesn't matter now because I'm a stroke and cardiac arrest survivor and can't drive anymore especially a new Vette
I'm waiting for the first guy to do an 8-1 exhaust system. The firing order of the GM V8s end up making it sound pretty exotic when the exhaust is done in that configuration..
What kind of a sports car only has an automatic transmission? I'll stick to my fire breathing C2 with its tri-power 427, side exhaust and proper 4 speed. The visceral experience of slamming it through the gears while those pipes roar, is what a real sports car experience is all about. Not as "techie", but It's raw experience is far superior.
Sadly, all exotic/supercars are doing away with true manuals. Corvette was one of the last to do it, Lambo, Ferrari etc hasn't had a true manual in quite some time.
It is a double clutch transmission it does not have a torque converter so it behaves like a manual transmission but shifts much faster than a manual transmission.
@@ShawZam yea it would be. GM has built many V8 engines that are surprisingly easy to work on . The first gen ls cam could be removed without removing the heads ... Not the newer v8s tho
@@lard1892 I think it's every 100k miles they usually recommend you change plugs/ wires. Ignition coils can act up sometimes to when you get up in the miles. By looks of it those parts should be easy to get to with the relocated design
So this was the original potential of the LT1 from 2014. I believe it still has cylinder deactivation with this new cam. Move of coil packs to the bottom is interesting.
Over the years Corvette has improved on Trunk space but now going to a mid-engine design this car will have the same problem as most mid engine cars- little or no trunk space at all! But that's the tradeoff for that design!
As for mods on the C8 LT2, is their any HP to be gained in changing the rocker arm ratio? They are already at a high 1.81:1. They say that you gain very little with a head change, even with high dollar AFR or Trick Flow heads. They have been porting and milling the stock heads for the best gains. They also state that you gain very little with an intake manifold change, they just do a little blending and porting on the stock LT2 manifold. It looks like you will need to change or mod almost everything on the motor, to pick up much HP over the stock motor. The 11.5 compression ratio tells us allot, the motor has been pushed to a much higher limit than the LT1.
Thank you for sharing the info on the LT 2 and I think Chevrolet really knock it out of the park this time. I went and looked at the C8 over the weekend and I am very impressed and I can’t wait to drive it.
The intake reminds me of the late gen truck manifolds with the long open runners and very tall overall clearance. I'm surprised the stock unit stayed 87mm, since 90mm and bigger has been seen in previous LS/LT engines. Did the LT1 come factory with 1.8 rockers or is that new?
Question: How many metal (i.e. durable, long lasting) engine parts now have cheap plastic replacements that begin to crack before the car has gone 100k miles? I hear BMW is doing this.
The pushrod V8 is a design that was right, right from the start. Reliable as a stone, powerful and proven. Other benefits include lighter weight, smaller physical size, fewer rotating parts and a maintenance free valve train. No chain tensioners and guides that need replacing, no belts, belt tensioners and horribly expensive visits to the dealership associated with OHC and DOHC designs. Indeed the pushrod engine is so reliable, it is used in aircraft. For all you brainwashed non-thinkers that will say they cannot rev, study the 500CI Pro Stock motor which develops over 1,200BHP at 11,000RPM. Wake up. I am a diesel enthusiast so I believe any engine that has to rev to make power is a waste anyhow.
I agree with everything you said about ohv vs ohc/dohc engines but these youngsters think ohc is the greatest thing since sliced bread i've made the same arguments that you have about the advantages of ohv vs ohc but to each their own
dittos...hope the pushrod engine makes a comeback. Don't care about speed, power, economy...just want reliability, easy to repair and a roomy engine compartment
It looks like function of the lifter valley scavenge pump is absolutely crucial. If it were to ever stop working - for whatever reason, all of the oil will pool in the valley. Just a liability of removing all the oil drains in the lifter valley. And yes, the lady singing in the background blows.
You are right about the electronics. Why is it encrypted? Total bs. They want us to go to their licensed vendors, instead of letting us do it on our own. Someone will either steal, break or work around the encryption.
So u can't change anything because if some young kids dad buys him one you know he's gonna try to get more power out it with a hand held and he'll put around a tree and him and all that fiberglass and plastic will be in a million pieces
Wow rear cross member and exhaust manifold removal just to change spark plugs?! Let's hope that is all, instead of a engine-out service like most mid-engine sports cars....GM techs are gonna love $$$ the C8 just for this aspect.
People are focusing only in the msrp. Everyone looks in love with a cheap supercar. And don't think about the maintenance costs of a powerful mid engined sports car. I think we will see the 2nd hand market full of these in some time, due to people that can't afford that manteinance. Specially on the future more powerful variants. The manteinance will be definitely a lot more expensive than in the previous gen car.
Michael Sullivan / You know what, when you’re right you’re right. And I hope that since Chevy now has a mid engine Vette that they do take it to Le Mans and kick ass in a $60,000 car
@@limabravo6065 I understand what you're saying about seeing the underdog, mid engined 2020 Vette at LeMans competing with it's higher priced competition, but the C7 is out there right now competing with the others.

Hello, does the lt2 features both port and direct injection or does it have only direct injection ? If it’s the cas do you think it will have carbon build up issues like all the other direct injection engines ?
I wanted to do a video on C8 - is there a centrifugal supercharger available now? Procharger does not have anything in production as I just spoke w them today. I have a C8 on order and am going to start a TH-cam channel - Looking for folks to do collaborations with now as we build the channel.
A pushrod flat plane Crank LT2 would have been Better and revs to 10k. Then Bi-turbo for the ZR-1 version. Can't wait for a Wagler Duramax 6.6 V8 version since there is more room to play. #rollingcoal
Thanks! Seems strange that the Caddy v8 can produce 550 hp while the LT2 is about 495 hp. Wouldnt it have made sense for GM to use Caddy's design and modify it for mid engine specs?
@@briangasser973 The LT2 was already an existing design and cheap since their cars and trucks share that family of engines. Remember that the blackwing horsepower is through forced induction while the LT2 is naturally aspirated. The Blackwing would make more sense for a more expensive ZO6/ZR1 since it's a new design and not as abundant while keeping the LT2 for the "cheaper" Corvette as an entry point.
@@briangasser973 People get too fixated on HP numbers. The LT2 is NA, and this Vette being mid-engined if it truly runs 0-60 in 3 seconds or less I mean do you really need more power at that point? I'm sure the Z06/ZR1 versions will have more HP. This is plenty for the base model.
I’ve always wondered why Chevy still uses a single cam, pushrod V8 in their performance cars, especially the Corvette while many other makers have switched to twin over head cams, but somehow they make it still work after all these decades
Because it's less costly to build plus weight savings ! It keeps the American push rod nostrogy. I think the only issue is valve spring fatigue and floati. Just replace them with high quality valve springs after a certain mileage.

The headers look like they're natural for speed boats too XD
Lt5 from the 90s was handbuilt by Mercury marine, who then proceeded to make an lt5 powered boat, towed by an lt5 powered Corvette. It was a funny and amazing thing to see.
“Mounted Mid-Engine”. Great quote. Lol
Man, this engine with a roots style blower will be incredible.
So different cam, Intake manifold, and stock headers.. Nice..
@lenny 034 Yea, but I believe the LT1 in the GrandSport had that already.. It’s nothing really new..
Were you expecting something else? A pretty decent little bump from the LT1. Bigger power bumps than the LS2 gave over the LS1 back in the day.
@Chuck Beef No.. I love the car and everything about it..
Camaro_LT1 Oh. The double period thing.. had me thinking you were being sarcastic. Lol you’re right its looking to be a pretty great car.
I'm keeping my C7 manual transmission for 3 pedal engagement fun when I get a C8.
Sure she slip right in....
Drive a dual clutch and you ll soon forget the manual.
LT2 is a great update to a very reliable Corvette Engine. How well will this improved engine with 11 to 1 handle 91 octane fuel when it needs 93 for proper performance?
Engine looks great, but that instrument cluster is beyond BLAAGGGHHHH!
Yeah bland econocar digital guages
@u aint bout it analog guages would've been better
LONG LIVE THE PUSHROD!
Companies who usually race Corvettes had a definite say in the engineering of this beauty. Especially IMSA and Le Mans series. Sorry don't know which company competes with the R series Vettes.
Interesting and nice video. Many thanks.
Good bye Toyota Zupra.. Nice knowing ya.. 😅😅😅
You think it is better then Toyota???? You can buy a 1999 Corvett for
$3000.00 Supra 1999 for $80.000????
Except...the new Supra is a rebadged BMW. Why don’t you give us some price information on 1999 BMW’s.
Giancarlo Cesari that shows how overpriced they are
my stage 3 (downpipe and injectors tune only old EJ motor) 2015 Sti w eurothane driveline mounts and springs/big rubber will out run and outhandle a new zupra w my kids in tha back lol. And its nothing near what my old Evo could do.. New cars hype machine. Kids need to get off the supra titty new one and the old 90s one that was same as a Lexus SC300 lol
@@carlocesari1 Who said anything about previous generation Supra? I'm talking about the new Supra.. With the BMW engine, and interior as well. The new Corvette is faster, nicer, and overall a better package..
Working on that engine bay will definitely suck, and as for the cylinder reduction use I'm not a fan of.
CAFE standards?
Minute 1:16 You said it's mounted mid engine? What is mounted mid engine?
All I can think of saying is"wow" and totally awesome dude LoL I'm Peter from Hamilton Ontario Canada and 47 years old and always wanted a Vette but can never afford one but it doesn't matter now because I'm a stroke and cardiac arrest survivor and can't drive anymore especially a new Vette
@Matthew Gerhardt thank you sir you as well
I'm waiting for the first guy to do an 8-1 exhaust system. The firing order of the GM V8s end up making it sound pretty exotic when the exhaust is done in that configuration..
What kind of a sports car only has an automatic transmission?
I'll stick to my fire breathing C2 with its tri-power 427, side exhaust and proper 4 speed.
The visceral experience of slamming it through the gears while those pipes roar, is what a real sports car experience is all about.
Not as "techie", but It's raw experience is far superior.
Sadly, all exotic/supercars are doing away with true manuals. Corvette was one of the last to do it, Lambo, Ferrari etc hasn't had a true manual in quite some time.
Paddle shifting is what the latest generation wants. I agree with you...manual shifting is more satisfying.
It is a double clutch transmission it does not have a torque converter so it behaves like a manual transmission but shifts much faster than a manual transmission.
This is going to be painful when its time to do a tune-up...mid engine is all fun and good but pain to work on
I'm pretty sure I heard somewhere they designed it to be able to do tune up with engine still in car.
@@joedmac78 That would be great and if changing the oil is easy then its win win
@@ShawZam yea it would be. GM has built many V8 engines that are surprisingly easy to work on . The first gen ls cam could be removed without removing the heads ... Not the newer v8s tho
Tune up??? You mean change spark plugs once in a lifetime? Air filters three or four times??
@@lard1892 I think it's every 100k miles they usually recommend you change plugs/ wires. Ignition coils can act up sometimes to when you get up in the miles. By looks of it those parts should be easy to get to with the relocated design
My only gripe. It looks like engine accessories are hard to work on without dropping the engine/ rear cradle.
So this was the original potential of the LT1 from 2014. I believe it still has cylinder deactivation with this new cam. Move of coil packs to the bottom is interesting.
It does still have the AFM.
Over the years Corvette has improved on Trunk space but now going to a mid-engine design this car will have the same problem as most mid engine cars- little or no trunk space at all! But that's the tradeoff for that design!
It can hold 2 sets of golf clubs or a set of 5 suitcases. Storage in front and enough room in back to store the targa top.
@B is for Build This is the perfect engine for your shenanigans!!!!
lmao
Haven’t found out if the crank shaft is cross plane or flat plane style?
Doesn't sound flat plane, but I'm not sure
It is crossplane, it is tricky to use a flatplane crank in a pushrod motor.
As for mods on the C8 LT2, is their any HP to be gained in changing the rocker arm ratio? They are already at a high 1.81:1. They say that you gain very little with a head change, even with high dollar AFR or Trick Flow heads. They have been porting and milling the stock heads for the best gains. They also state that you gain very little with an intake manifold change, they just do a little blending and porting on the stock LT2 manifold. It looks like you will need to change or mod almost everything on the motor, to pick up much HP over the stock motor. The 11.5 compression ratio tells us allot, the motor has been pushed to a much higher limit than the LT1.
Thank you for sharing the info on the LT 2 and I think Chevrolet really knock it out of the park this time. I went and looked at the C8 over the weekend and I am very impressed and I can’t wait to drive it.
The intake reminds me of the late gen truck manifolds with the long open runners and very tall overall clearance. I'm surprised the stock unit stayed 87mm, since 90mm and bigger has been seen in previous LS/LT engines. Did the LT1 come factory with 1.8 rockers or is that new?
Will it have the massive intake valve issue that many DI engines have? Maybe we should wait for the dual injection version.
The cut always are awesome
Question: How many metal (i.e. durable, long lasting) engine parts now have cheap plastic replacements that begin to crack before the car has gone 100k miles? I hear BMW is doing this.
Plastic timing guides absolutely irk me.
Most manufacturers have went to plastic and yes a lot of the plastic doesn't make it past 100k
In the next yet years GM will make many changes that will be great for this C8 Vette
No shit?
If it was not for the near perfectly square steering wheel the C8 would be a masterpiece.
The pushrod V8 is a design that was right, right from the start. Reliable as a stone, powerful and proven. Other benefits include lighter weight, smaller physical size, fewer rotating parts and a maintenance free valve train. No chain tensioners and guides that need replacing, no belts, belt tensioners and horribly expensive visits to the dealership associated with OHC and DOHC designs. Indeed the pushrod engine is so reliable, it is used in aircraft. For all you brainwashed non-thinkers that will say they cannot rev, study the 500CI Pro Stock motor which develops over 1,200BHP at 11,000RPM. Wake up. I am a diesel enthusiast so I believe any engine that has to rev to make power is a waste anyhow.
I agree with everything you said about ohv vs ohc/dohc engines but these youngsters think ohc is the greatest thing since sliced bread i've made the same arguments that you have about the advantages of ohv vs ohc but to each their own
They are brainwashed victims of advanced marketing techniques and cannot think for themselves. Sadly they just little parrots.
dittos...hope the pushrod engine makes a comeback. Don't care about speed, power, economy...just want reliability, easy to repair and a roomy engine compartment
I like those numbers
Nice vid
It looks like function of the lifter valley scavenge pump is absolutely crucial.
If it were to ever stop working - for whatever reason, all of the oil will pool in the valley. Just a liability of removing all the oil drains in the lifter valley.
And yes, the lady singing in the background blows.
You are right about the electronics. Why is it encrypted? Total bs. They want us to go to their licensed vendors, instead of letting us do it on our own. Someone will either steal, break or work around the encryption.
Working on that video. I will let you know how it'll most likely be done.
So u can't change anything because if some young kids dad buys him one you know he's gonna try to get more power out it with a hand held and he'll put around a tree and him and all that fiberglass and plastic will be in a million pieces
Its because of warranty reasons, they know how much peopke want to modify those cars. Btw, they always leave a small crack somewhere.
leoaleromm Once you make changes the warranty is void.
Jon Richardson People are going to modify them especially people who race them.
The picture looks like the exhaust manifold would work great for a turbo set up in other cars
HP Tuners are able to tune the GM E99 already on the ZR1
Like!Ah that plastic engine cover is really rad!!
Wow rear cross member and exhaust manifold removal just to change spark plugs?! Let's hope that is all, instead of a engine-out service like most mid-engine sports cars....GM techs are gonna love $$$ the C8 just for this aspect.
People are focusing only in the msrp. Everyone looks in love with a cheap supercar. And don't think about the maintenance costs of a powerful mid engined sports car. I think we will see the 2nd hand market full of these in some time, due to people that can't afford that manteinance. Specially on the future more powerful variants. The manteinance will be definitely a lot more expensive than in the previous gen car.
Wondering if the LT 2 intake . Wil fit on a c7🤔
It should fit, but you may not have a hood.
Not sure this and the Subra will be in the same price range in Japan. USA is not the only market for Toyota.
the throttle body is now facing the other way towards the ring gear,, but on others its facing the accessory drives,, am i correct,, or not
Is the LT2 all alloy?
This makes the Ford GT’s price look kinda silly as the power figures we have are initial base model #’s
The GTs price was silly long before the C8 showed up.
Michael Sullivan /
You know what, when you’re right you’re right. And I hope that since Chevy now has a mid engine Vette that they do take it to Le Mans and kick ass in a $60,000 car
@@limabravo6065 I understand what you're saying about seeing the underdog, mid engined 2020 Vette at LeMans competing with it's higher priced competition, but the C7 is out there right now competing with the others. If the C8 is as good as Chevrolet claims, with all the money added to the platform that it takes to make a car LeMans competitive, the C8 should be brutally scary in competition
I hope the car performs as promised.
Hello, does the lt2 features both port and direct injection or does it have only direct injection ? If it’s the cas do you think it will have carbon build up issues like all the other direct injection engines ?
Only direct injection like the LT1.
Just what I wanted to hear I'm installing the 2 cam in my 2015 LT1 Z51 motor in my 57 Chevy sedan delivery to deleet the afm dod
Great info, well done
Is the DCT an option or is a MT an option?
Are the return oil pumps electric?
First mod to c8 is titanium exhaust
this round the corvette wins
nice job chevy
So when are they gonna put this engine into the camaro ss?
I miss the 427----with DI and all the improvements I bet 550hp would be doable
Gunna be hundreds of Paul Walker's once this car comes out
I wanted to do a video on C8 - is there a centrifugal supercharger available now? Procharger does not have anything in production as I just spoke w them today. I have a C8 on order and am going to start a TH-cam channel - Looking for folks to do collaborations with now as we build the channel.
A pushrod flat plane Crank LT2 would have been Better and revs to 10k. Then Bi-turbo for the ZR-1 version.
Can't wait for a Wagler Duramax 6.6 V8 version since there is more room to play. #rollingcoal
A 10,000rpm 6.2 and a Duramax option? That's quite an imagination you've got there, Ted....
How does the LT2 differ from Cadillac's new Blackwing V8 used for the CT6? Is it the same engine?
No. Totally different...DOHC, TwinTurbo, displacement, different engine family, non-interchangeable parts, etc.
Thanks! Seems strange that the Caddy v8 can produce 550 hp while the LT2 is about 495 hp. Wouldnt it have made sense for GM to use Caddy's design and modify it for mid engine specs?
@@briangasser973 The LT2 was already an existing design and cheap since their cars and trucks share that family of engines.
Remember that the blackwing horsepower is through forced induction while the LT2 is naturally aspirated.
The Blackwing would make more sense for a more expensive ZO6/ZR1 since it's a new design and not as abundant while keeping the LT2 for the "cheaper" Corvette as an entry point.
@@briangasser973 People get too fixated on HP numbers. The LT2 is NA, and this Vette being mid-engined if it truly runs 0-60 in 3 seconds or less I mean do you really need more power at that point? I'm sure the Z06/ZR1 versions will have more HP. This is plenty for the base model.
prettiest production small block
Correct me if I'm wrong but I thought a LT1 was a 5.7L not a 6.2L?🤔
Nice video!!!
I’ve always wondered why Chevy still uses a single cam, pushrod V8 in their performance cars, especially the Corvette while many other makers have switched to twin over head cams, but somehow they make it still work after all these decades
Because it's less costly to build plus weight savings ! It keeps the American push rod nostrogy. I think the only issue is valve spring fatigue and floati. Just replace them with high quality valve springs after a certain mileage.
What happens _IF_ the LT2 V8 has an Iron Block?
That would mean more weight over the drive wheels!
It means it can hold more boost .
What color choices are available for the LT2?
How hard will it be to do maintenance....or what is estimated cost at dealers?
