GM High-Tech Performance Gen5 LT1 Small Block engine build

The new GEN5 LT1 engine build animation fresh from the GM Gen5 release.

[@chevyman5436]

Amazing! I look forward to the new LT1's development in the years to come! You rock GM!

[@SavageJim01]

One way to protect against oil taken from the PCV system from polluting your fresh fuel-air charge is to install oil separator cans or oil collector cans. These things work wonderfully and really prevent such mishaps, thus doing exactly what you said: improving fuel economy as well as allowing your engine to produce its nominal advertised BHP. These oil catch cans look just like these cans in this vid: watch: xse-Vw_i8Ms These ones are for Ford, but they also have them for Chevy and Mopar.

[@vomErsten]

LS series, first off, are entirely cast from aluminum instead of iron like the LTs. They also use coil ignition instead of distributor-type set-ups. The cylinder firing order was changed from 1-8-4-3-6-5-7-2 to 1-8-7-2-6-5-4-3. The result is a much smoother operation; it's one of the reasons you can't really get the old-school, aggressive-cam thumping sound out of them. They are more of a growl. The curved intake runners also force more air into the engine, allowing for easier breathing.

[@Mazak23]

Good to see it'll be built back at the old Tonawanda engine plant in Buffalo where most of the old Corvette engines were manufactured.

[@vomErsten]

Ha ha, I wish! Naw, it's a black/black base coupe with a 6-speed. All 6-speed Corvettes came with the LT-4 in 1996, and vice versa. Probably one of the most underrated packages in the history of the Corvette. Thanks though!

Pushrod = light weight low center of gravity, low maintenance cost, cheaper upgrades. more low end torque, less wear to make power, larger powerband 525hp LS3 $7.5k 400lbs 84.6hp/liter with low end torque DOHC Low durability, High maintenance cost, expensive and difficult to tune, high center of gravity, take up more space with less displacement, Tears itself up trying to make hp piston speed to make power 82.58mph 5.0L 412hp $8.5k 444lbs 82.4hp/liter less low end and peak torque

[@sategllib2191]

Nobody listen to this, it's mostly lies. Low center gravity, cheaper and low end torque for pushrod is true. Higher center gravity and take up more space for ohc is true. That's it

[@ihatecrackhead]

@@sategllib2191 5.0L piston peak piston speed is 82.5mph, not the average over the entire stroke. short rods to stroke ratio means the piston is being pushed against the cylinder wall at a steep angle, this cause the piston to accelerate mid stroke use a steep angle also means wear and tear this means the piston is actually traveling faster than the crankshaft mid stroke but slower at TDC and BDC the mid stroke piston speed helps activate the runners with high velocity air, which means if you time the valve closing at the right time, you can be more than 100% volumetric efficiency without valve overlap or scavenging problem is even though 6.2L is 20% bigger, 5.0L only gets 3% better fuel economy driving slowly yet a 6.2L and a 5.0L in a race, the 5.0L would run out of fuel first. needing high rpm to make power means you're actually displacing more per minute in fuel/air. all those extra cams and valves come at an expense(not just wear and tear) at full throttle mustangs run out of fuel faster than camaros if you need help with a comeback, I can help you but it won't change these facts

[@SavageJim01]

GM has always had OHC engines. During the 60's, GM was planning to introduce a SOHC 427 to compete with Fords SOHC cammer, & Mopar's SOHC & DOHC 426 Hemis. But NASCAR banned these so the Big3 dropped them (except for Ford). The 1990-95 ZR1'Vette had the LT5, DOHC 32V 5.7L, and it was completely untouchable; Ford&Mopar couldnt beat it. Caddy had the DOHC 32V Northstar engines. And the 2010-present Camaro V6 are all DOHC 24V w/ cam phasing, the newer ones making over 320BHP stock.

[@cliffordpurk85]

I have not done much study on any of the LT engines..most of my research and experience goes to the LS series but since GM has designed this new LT monster im going to have to start doin some research and learn more about the LT engines..im a HUGE GM fan and def wanna know more about those engines

[@Tbolt1000TForLife]

glad to see it's still a pushrod engine, and not a pos overhead cam engine, it makes sense because cylinder deactivation wil not work on an overhead cam engine

[@vomErsten]

The irony is that the LS7 gets pretty decent mileage despite its big 7.0L displacement, ha ha. It's all about how you drive. I actually like the L98s, they have gobs of low-end torque and that makes them very fun to drive around town. Some modifications to help it breathe and a more aggressive cam can raise that power up past the 300 mark easily. They also don't have the Optispark to deal with, which isn't all that bad but can get dicey under moist conditions.

[@ctusser]

It's just good timing. The first LT1 was released in 1970 model year, and the second time LT1 was used was 22 years later in the 92 model year. Guess what? It'll be 22 years again for the 2014 model year to be released with the LT1 again. Yea, we're that old, lol

[@SavageJim01]

Actually, onegoal2006 is correct. I read everything in this vid that you're arguing about and he is correct. There is proof and its not in any magazines. McGees made DOHC top fuel engines that made 10,000 hp. McGees DOHC engines were so powerful that all the other engine builders made NHRA ban DOHC. The pushrod top fuelers couldn't beat the McGees engines

[@TheLTXCamaro]

the main difference is the reverse flow cooling. Instead of water going to the intake it goes into the heads then to the block then back to the heads then back to the radiator. Meaning higher compression for street use. Higher compression = more power!!

[@Hardy_H_H]

i stand corrected =) . just did some reading on this 2014 new LT1.

[@markjmaxwell9819]

Still a nice engine Pretty spot on for a pushrod engine. Needs the LS7 headers otherwise spot on.

[@nocki5oh]

@Justin Nichols It's still 6.2 liters. Not 5.5 like rumored.

[@Blackneck1994]

Well this is beautiful... finally GM is adding new tech to their small block. BUT, not too much so that they are deviating from their general 2V pushrod design, love it. GDI was a good choice, as well as VVT. Although the gas mileage is nearly the same as my old 6 speed LS1 running on all 8 with no VVT, cylinder deactivation, or stratified charge mode like on this GDI engine? Whatsup with that GM lol? And why name it the LT1..? Are they that ashamed of the Gen II LT1 ahah. Great engine.

[@ap4709pk]

Wonder if a catch can would help with carbon deposits.

[@vomErsten]

Are you referencing the LSx or the LTx? I ask because the Gen II SBC LT1/LT4 had reverse-flow cooling as well. That was one of the key changes that allowed GM to bump the power up to 300/330 (respectively) from the 240 being made by the L98. But yes, this change does exactly what you say it does.

[@2k6gto]

I like it. Will probably be more like 465ish hp when the final #'s come out.... I mean look at the ports on the heads! Not crazy about DOD, but oh well... C7 is going to be a great car.

[@SavageJim01]

Cobra jet crate: M-6007-CJ13, $16495, over 500BHP naturally aspirated, tuned to over 700BHP within the limits of NHRA. The LS7 7.0L costs $16956 from West Coast Corvette, $16955 from Southern Performance, and similarly at other sites for MSRP. If you don't believe me, look up Ford Racing Direct and those other sites I mentioned.

[@G8GTJav]

Sweet! Can't wait to see the full review in GM High-Tech Mag. Those intake ports look huge & that intake design is really different. Longer runners for more torque? Glad to see that Gen 5 is also a compact, tidy package. Are they really going to call it LT1? Should pick something else.

[@vomErsten]

Oh right, I forgot. A C4 Corvette is so insanely expensive to buy and maintain, therefore I must be lying about driving one. Run along, little troll. Also, next time, try reading up on the topic before commenting. Thanks! ;o

[@HiShBL2]

I'm in love .

[@kbert63]

I foresee the fist small block to make 1000HP. with out any forced air induction. Just look at the size of those intake ports!

[@SavageJim01]

This is not a 5.7L 350ci, it is bigger: 6.2L, 378ci. This LT1 is not the olde LT1 from 20 years ago, its bigger and better by far. For 2014, the 6.2L LT1 will probably only replace the LS3 & L99 engines. The base Corvettes will gut the new LT1, &rumor has it the Camaro SS will also get it. I dont think the LS7, LSA, and LS9 will be replaced; I think they will still go in the Z06, 'Maro ZL1, & 'Vette ZR1 respectively.

[@CamaroAmx]

this is the new LT1, not the old 92-97 LT1 or the early 70s LT-1. this LT1 will be replacing the LS (gen 4) engines.

[@SavageJim01]

Nope. The price I quoted is from Fordracingdirect. The regular stick 5.0 is M-6007-M50, $6249. Sealed 5.0 M-6007-M50S is $6325. Aluminator M-6007-M50NA is $8050. Aluminator for boosting M-6007-M50SC is $8350. Aluminator w/ installed S/C is M-6007-A50XS is $14449

[@nedaCFilms]

Why do people never read the available video descriptions...

[@cliffordpurk85]

I dnt think there gonna replace the LS engines with this new LT..there gonna have ta produce more than just an LT1 to power there muscle cars..they cant just place an LT1 in ever car they have...does anyone know if the ci of this engine is still a 350? If so thats pretty impressive!

[@vomErsten]

I wonder if the high-end version will be called the LT4 and have its manifold painted red... I myself have a '96 with the old LT4 in it. ;D

[@vomErsten]

Where did I say anything about a Camaro? I drive a manual '96 Corvette...you know, the car that the LT-4 was designed for.

[@JohnnyAnderson1]

So this is basically a gasoline duramax! Lol way to go gm

[@mr.boostang2064]

Was it missing 4 spark plugs or was the car on fire???

[@Nickster7ROR]

I have an lt1 in my '95 camaro. What was the difference between the lt1 and the ls1 design? Not hp and torque, I know those figures!

[@mrmete]

the v6 does not make 323 to the wheels the ls1 makes around 290 to the wheels where are you getting your information from

[@Blackgam3r]

My guess is because of all the electronic BS that government mandates. The C7's frame is actually lighter than the C6's but because of all the added gadgets and do-dads the car still weighs roughly the same. Most of the weight was added back. Back in the day a car was engine, transmission, gas pedal. :P

[@ramiropanfilo4222]

will it fit in a 4th gen camaro?

[@azbertx]

well, direct injection and variable valve timing for the new corvettes...

[@ihatecrackhead]

I know how a sealed motor works Chevy also sells $6k sealed 6.2L engines, they even sell $6k 430hp LS3 non sealed engines but i was trying to use a close comparison $6,198 paceperformance. com/i-7141040-19301326-ls3-6-2l-430hp-gen-iv-engine. html

[@Feenyxxx95]

Wish they'd have used a different rpo. lol I had a talk with a friend about this couple months ago and something I brought up is present in this videos comment thread lol. When talking about the LT1, the first question is going to be "which one?". I hate that for some reason. Why couldn't it be LS5 like was originally planned? Or hell LT2 or something. Why a third LT1? oh well.

[@chevellenut1968]

grand sport nice car

[@mr13377]

sweet!

[@Hardy_H_H]

title is wrong, this is not an LT1 this is an LS1

[@TheLTXCamaro]

Yeah im talking about Gen 2 small block. The only difference in gen 1 and gen 2 is the opti, water pump, and reverse flow cooling. I kinda wish Gen V had reverse flow cooling lol. Talk about 13:1 compression on pump gas ;) L98's were one of the were small blocks ever made imo. My favorite small block was the DZ 302. Best big block was 454 LS6. I still wish GM can produce a New Big Block but no one will buy since dumbasses are all about gas mileage nowadays.

[@MatthewQuinton]

too many people get way too upset about the whole pushed vs ohc debate. Really they're not that different anyway.

[@Onegoal2006]

Ur wrong again. Direct Injection or DI is better because it lts U go 11.5 compression. But because its a pushrod, U cant' go better compression like 12.5 to one because pushrods detonate. Put DI in a DOHC and U can go 12.5 to one and 13.5 to one. Diesel engines are direct injection and they go 14 to on or even 17 to one compression.

[@chevyllac091]

Its been done, google it

[@GreenGoRacing]

1000hp NA isnt coming from any sbc motor with stock ports lmao

[@LaswellB]

Not even close to being an ls3. Look at the water pump location, look at the valley cover, cam driven fuel pump for the rails, direct injection, etc etc.

[@Abstractedthought]

no engine cover please.

[@mrmete]

then your friends car is truly under performing ls1tech. com/forums/general-lsx-automobile-discussion/1598257-ls1-actual-rear-wheel-horsepower.html ls1. com/forums/f35/how-much-horsepower-does-stock-ls1-actually-make-96846/ they are putting out around 300 my buddies 02 was putting out 297 and 324 before he swapped for an ls3 and turboed it

[@SavageJim01]

Fancy seeing you here, son. No,pushrods see a lot of wear too. Look at the Z28 LS7: worse rod/stroke ratio, much faster piston speed at redline than the 5.0L, and pretty expensive in its own right. The 5.0L has more tuning options like variable lobe separation from TIVCT. Can't do that with pushrods.

[@Onegoal2006]

No Im' not. Chevy got sick of paying Lotus for the special DOHC ZR1 motor in 1990 &Chevy cant make DOHC. So Chevy lied to us by saying pushrod is better. If pushrod is so good, why does Camaro today use DOHC? Because DOHC is better!

[@SavageJim01]

And as always, the name calling begins. It's bad enough that two other jokers are stooping to mindless insults, now you are joining their ranks also. Son, calling me a moron don't make you right. You aren't even reading the crate engine details. So, let me walk you through it in proper detail:

[@marscobras8281]

thats an LS1 not LT1

[@mohalqeer36]

هذي مكينة المرهمين مطلوبة ﻻهل الجيوب. &

[@89riceeater]

Thats a ls3

[@tyronewalker1482]

CARBON !!!!!

[@Screamn4444]

want

[@Screamn4444]

no its not.

[@sategllib2191]

"High tech" puts cam in block haha

[@vomErsten]

How amusing; the infant who is demonstrably misinformed about the LT4 and the Corvette thinks he is in a position to demand proof. I post a picture, you will just say it is shopped or that I pulled it from somewhere else. I believe it is past your bed-time, little troll.

[@SavageJim01]

Funny how this vid is already polluted with two other guys E-thugging it at each other, and now, you, another notorious joker joins in. Son, for the record, the 5.0 stock engine is as little as $6250. You found the upgraded all true forged Aluminator PN M-6007A-50NA which is meant for nitrous, spray, etc. to produce in excess of 800HP.

[@TheLTXCamaro]

How many fucking times are you going to post? jesus man! Give it a break!

[@uriahbleue1947]

Dohc is the way.

[@MasterKeyMagic]

Then why did ford just go back to building pushrod V8’s with their new 7.3L which is essentially an LS engine?
