You know it’s good when the dyno run starts at 6800
Shannon Sisk Formula 1 used to idle at 5,000-7,000 rpm
What's it mean if you have a converter that stalls at 9000?
@@shawnmenzenberg6442 Very late reply but in simple terms the stall is the amount of rpm at which the converter starts to grab. If the converter stalls at 9000, that means it will take 9000 rpm until the converter starts to slip and then grab. Don’t know if this will help or not but I tried lol.
@@jgodshall80 this is no formula one. This is pure America baby
@@jgodshall80but f1 engines were purpose built 3.0 v10s not road based 7L v8s
457ci and heads the flow 490cfm. Yea no power adders here just high revving American muscle power
This is nuts and its true muscle Naturally Aspirated... I love it.
love a high reving na v8 scream 👍
SmoothCanoes right?on top of that it's 1000 hp AND na
Damn. What was the difference in collectors is the real question. That thing is a beast. Sounded amazing. Never seen a 1250cfm dominator on a LS before that is impressive all by itself.
Wow ! 8,832 Rpm !😲👍
That Motor Is Impressive for the Cubic Inch. Big Block Killer ! 😊
I've never seen so many experts in a comment section before,has2 b a record!
No record here.
I love big horsepower n/a V8s. 🤘
Whole new ball game when its over 2hp per ci..
And NA to boot.
Honda guys with 1.5 hp per cm3
@@glebos1710Didn’t know anyone made a 3,000hp NA K20.
@@Matthewzilla😂
Those headers are beautiful
Absolutely, probably the burliest I've seen on an LS build. The collector is a work of art.
Now thats an engine 👍
It would be interesting to see the difference between the smaller merge collectors and the larger ones that show up later in the video.
RAW Power!! no helps (turbo/supercharger, etc.) All motor is always the Best and the best Sounding too!!!!
Well they are gonna need some tough motor mounts
Nice daily driver engine.
The Only LS I respect cause it’s ALL FUCKIN MOTOR
yes V8 naturally aspirated same the nascar
You should donate this for a super clean and tough little 2wd 95 gmc reg. cab short box factory v8, 5 speed truck. Super rare. I've been trying to do a motor for, for at least 10 years. Either kinda had some of the money but not the place or time, or none of the above...Truck only has like 80k original miles on it, but lets face it they werent exactly building performance in the 90's..lol Even their "performance" performance wasnt performance.
that noise, it's like a demon
LS are just awesome!!
Is it even an LS anymore?
The only thing LS was good for is a toilet
@@ricktotz4078 GOOF
@@Agent_Clark yeah, it is. It's the LS platform. Are you going to ask that same ridiculous question for any aftermarket upgraded engine?
@@ricktotz4078 that's why it's the most popular engine swap in the world, right? That's why it still holds the record for fastest stock bottom end, right?
The LS scream is probably the best v8 scream there is
Get my 6.0 to run like this!Damm!
Holy hell they started the pull higher than my rev limiter 7k that’s ridiculous
That was unreal. I wonder what it cost to throw together... That was a pretty trick carb, how many air bleeds did it have on top for each barrel- like 3. Far out, what a monster
Daniel Brealey about 70-80 thousand
70-80 thousand is an absolute bargain for something of this nature
@@928pcarExtremely cool that it's n/a. Im not downplaying that a single but at all but I wouldn't really consider 70-80k for 1100hp a bargain.
@@sdriver6153 it’s a bargain lol name a car cheaper with more power
@@928pcar there's no mention of a car in the comment I'm replying to nor the video that the comment was made on. It's talking about the motor solely costing 70-80k, which is crazy to obtain 1100hp. Wouldn't be naturally aspirated but you can easily obtain 1100 from an LS for a lot closer to 10k .
Dang near NHRA Pro Stock performance, so I'm left wondering if this thing is going to eat valve springs like they do. What was the dropout sound just before they lifted the throttle, dyno cavitation?
DASWorkshop I wouldn’t be surprised if those engines went desmodronic instead of pushrod or even DOHC.
If you look down to the right of the video a carb hat or velocity stack falls off the wall
It is definitely a pushrod engine I would assume they are running a solid lift camshaft setup tiebar style roller lifters. And some serious valvesprings to turn 9000rpm. Prob .105 wall pushrods
why turbocharge if we can go N/A :)
Absolutely true!
True but..... this type of na motor is gonna murder your bank account again and again to build it. While na motors are sweet as hell, turbos are the best bang for your buck.
@@aaronjames11 maybe in your country.. here is "easier"/"cheaper" to tune NA cause performance parts are expensive and handwork not.. making a full cylinder headwork, replaced cam, are cheaper than a basic turbo kit only!
@@soledadpalomino7022 This engine is not cheap and it would probably be more expensive to make 1100 hp NA like this. They mention custom heads, most likely ported, also likely: custom lightweight pushrods, titanium valves, custom pistons and rods. It's not easy to get a pushrod engine to rev to 9k (if easy = taking something cheap/stock to make 1100hp).
RPMs kill engines, especially when they rev to 9k. LS engines are great since they make lots of power at low revs.
My bunghole is naturally ASSpirated too😂
How many gallons to the mile does it get?
The Vacuum pump & Dry sump pump belts were like ...WTF!!! @ 0:38
Man, what is the maintenance like as far as the valvetrain is concerned?
What is the Bore/Stroke specs? Large Bore / Short Stroke helps achieve 9,000 RPM easier and engine lasts longer. Old School SBC 302 (Z28) had 4 inch Bore and 3 inch Stroke. It could run at 9,000 RPM no problem.
Wow what a sound !
at 0:13 how is that engine running with no induction system. I was like wow that's clean looking neat set up.
It's not running. just a picture.
What carb is that? What size? Thing sounds amazing.
this thing howls!!
I too noticed the 'howl' above 7,500 RPM... NA engine with proper ports, header specs, etc. can take advantage of standing pressure wave and awesome volumetric efficiency.
How many rpms? All of em
That's some serious rpm
its very impressive
The size of the carb is ridiculous in a good way
She's a singer
Little boost and this thing would go through the roof!
Or at least the pistons would be😂
The hubby builds engines just like this.. Very impressive ever time too!!
Is it possible for him to build me one
@@Jayvisionary Yes, of course he will, friend.
I used to think high revving 4 holers were the shit.
Then I went for a ride in my first V8, and never looked back. 😂 this thing sounds just rowdy.
VERY ROWDY!😮
Nasty carburetor what four air bleeds on top of each barrel.
I'd like to see the build sheet for the carburetor.
You can bet there was a lot of trick stuff done to it
what fuel is it using??
this engine achieves 137NM × liter, the ferrari 458 achieves 120NM × liter, a 2013 F1 V8 achieved 123NM × liter, all of these with high single octane gasoline so I have a slight suspicion that the engine in this video uses gasoline with a small% ethanol, or something like that or maybe I'm underestimating it and actually use high octane plain gasoline if so it would be very impressive
Evil, wicked, mean, and nasty! Would really like to see this installed in something and make a few passes at a drag strip.
It's been running in the US in a Holden Commodore
@@STREETMACHINETVis they a v8 b
jeez. are the belts supposed to look like that?
GLC jonsan308
Umm yes
Cogged belts can run lose and they are good if your hunting down every last hp.
IWORKYOUWATCH is it cuz they potentially expand?
Shit tripped me out when i saw it lol. Kinda low on car experience back then2
It sounds angry and happy at the same time! 😡😁
Which is the most powerful engine for any car ..i want a engine for my car
Cleetus needs this in Leroy with twin turbski's
is that world record on n/a lsx engines?
+studio571
Not sure if it's a record but it's pretty damn impressive.
studio571 not a lsx sbc damn hot
Patrick Charette do you see the equally spaced headers just because it is running a distributor doesn't mean it's an LS you can buy a timing box that will let you run a distributor on an LS engine it's a lot easier to dyno them like that
The valley plate proves it's an ls.
studio571 its probably an ls next block
Is this strictly just a drag engine? Or could it be used for track as well?
This was a drag engine
I'm thinking Suburban with 2.73 gears. Am I right?
Holy Mother of God. Where can I get me one of these for my Monza project??
It tells you in the description , right next to the video.
what is the setup and compression ratio
no it's not the world record Judson massingill at School of Automotive machinist has eclipsed that and he did that over 10 years ago
the SAM engine did just under 1100
@Mr. Mix, the SAMTech engine was under 1100hp but that was over 5 years ago. Currently that exact engine makes 1106hp from a 435Ci, revving to 9,500 rpms. And it hasn't been tweaked in ~2 years.
I'm guessing 15:1
I will take 2 thanks ❤
What's the build consist of?
Is there any spraying or any power adders in this engine
No
Nice, what size carb is that?
So they only have 3k of usable power?
Do these heads have the dimpling on the intake ports?
\
sniper1334 Probably. Seems like a lot of high hp na engines are doing this. Less drag on the intake air as it enters the motor. Like a golf ball through the air
How much and where can I purchase?
What headers?
Single plane intake and one carb. What's funny is 10 yrs ago they assumed for 900-1000 that you needed a tunnel ram.
And based off what they were working with they were right😂 those old cars had poor compression and sloppy tolerances.
so is the carb causing postive pressure?
No, the intake runners...
no.. school of automotive machinist in houston have made more.. but never the less extremely impressed! Great job you guys!
So how do we get one.
The way that thing twists up.... it looks like it could break the dyno....
Sounds good. These engines run great once you install a carb and real intake on them.
Damn right brother
It's mostly the intake manifold lol, carb or FI they will make this power. SAMTECH made 1106 out of a 435ci with the same intake manifold, but fuel injected.
YES
Looked like it was going to rip its self off the Dyno
Single carb dam and it spun right up
What kind of engine is this & specs??
The most expensive you ever seen...
Mmmmmmmaaaaaaannnn that Sounds Angry....!!!
What is the displacement of this engine?
470-something
How is this making 1100hp all motor
HIGH compression and LOTS of rpms. I can't speak exactly for this engine because I don't know 100% what the specs are. But SAMTech pushed something like 15:1 compression and used C16 fuel, this allows them to spin a 435 cubic inch motor to 9,500 rpms. This one being a 457 and spinning less (8,500'ish? hard to tell) I would assume its still very close in compression and fuel used.
Probably 450cfm head flow too. With high compression 14:1
It's close to sucking that aluminium vent down the intake.
Build sheet?
8800 RPM holy shit
And still no simular designed straight shot intake for the big block chevy.
***AMAZING***2.5 hp per cubic inch from a pushrod V-8....
Naturally aspirated
@@STREETMACHINETV h÷
need a cam chain those cam belt ain't gonna last very long
Chains transmit crankshaft harmonics to the valve train but the belt does not!
How much would an engine like this cost? 40k$?
HOLY FUCKIN SMOKES, YEAH SHE BAD
What is an CID Type Head??
Ase Morton It a brand of head.
Sounds awesome. But something happened at the very end just before he throttled down.
Probably valve float, most all dyno pulls do the same if they pull it hard enough and long enough. When the valves float they start to roll over on the power curve at the end.
Now put a supercharger on it and watch parts fly
Ls next ???
Sweet ..!
explain how it works
+chalin P
Air, fuel and happy thoughts go in, exhaust, horsepower and angriness comes out
STREETMACHINETV torque reading so low?
it works because it revs to a very high rpm, horsepower is rpm x torque, if it can output a given amount of torque and sustain that amount, the higher the rpm the more hp you make... thats why old american engines always had high torque low hp example of big blocks making 380hp and 500lb ft of torque, they only rev to maybe 5000rpm, if they revved to 8000 rpm, which they can with the right valve train, they will make extreme hp numbers
Dyllidan ret so basically the lower the redline, the higher torque? and higher redline the higher hp? why is this
not necessarily, torque is made by the engine and shows its true strength, horsepower is torque divided by time, so horsepower is a mixture of torque and rpm=HP..... more torque = more hp, more rpm = more hp, more of both = a lot of HP, one way to make power is upping the engines size and strength (torque) in the case of a big block engine, but it may only rev to 5000 rpm, but because of its sheer strength still makes 400hp and 500 ft lbs of torque, another way is to take a weaker engine and make it work faster to produce hp, say a 3 liter v6 that makes 250 ft lbs of torque, but you may rev it to 8000 rpm and make 350hp, the real power comes in when you take a large high torque engine and get it to rev high like the smaller weaker engines, then you have a high base torque of say 500 ft lbs and 8000rpm peak at say 800 HP, the easiest way to think of it is with hammers, give a guy a 9 lb sledge hammer and he can swing it with a lot of force, maybe 30 times in a minute, give a guy a 2 lb ball peen and he can swing it with a lot less force but maybe 90 times a minute... the sledge makes more torque (strength) but the speed of the ball peen compensates for its lack of strength, the real key to power is getting a sledge hammer that can be swung as rapidly as a ball peen but still retaining its sledge levels of strength
457ci?
on 91 octane?
pretty sure it isnt on 91, maybe E85? or some f1 103 octane fuel, or just pure ethanol, idk
Godddddddddddddd No. It's likely pushing a compression ratio north of 14:1, I'd say at bare minimum it is 109+ if not 116 (C16)
Lmao no this is race fuel.
Good luck with 91 octane with 15:1 compression
Wow.
Too bad there was ZERO info...CID/ltrs, CR model heads, not even header, fuel used or carb size;-(
Samething I was wondering. Ifbthis power was on pump gas hell yeah its awesome. But on high octane race fuel keep it. Ill stick with force induction.
sounds like NASCAR
I want one
Whats the compression ratio?
Even at 20:1 there is no way in Hell it is putting that much power down all motor. Must be NO or just bullshit.
Rafael Lastra com lol ok.....
It's likely north of 14:1, I believe SAMTech's was 15:1 or higher I can't recall exactly. But it revs to ~9,500 and runs C16, not 100% sure what this one does.
Right at 17:1 CR...
On one cam ford. :)
And costing north of 30-50k

a nascar spec ls. wow.
0.145 hp per cc, amazing for such a large engine @7489cc. And such a simple looking intake, not even injected (I think?), or separate throttles per cylinder.
Cosworth DFV is 0.17 but under half the size so easier.
When your mainly WOT such as for a race engine, you cant beat good a good old fashion carburator.
@@Punk-Jw yes you can. EFI with ITBs beats any mechanical carb any day of the week.
@@spdcrzy Sure. Me and all the other top fuel dragsters must be doing it wrong 🤷♂️ 🙄🤦♂️ Come on bro... if there was a better way we'd be doing it..
@@Punk-Jw Top Fuel engines literally grenade themselves after every pass. And they're not naturally aspirated. That's not even comparing apples to oranges, it's comparing apples to nukes.
None of the highest-end racing orgs use carbs anymore when engine reliability is on the line. Hell, even NASCAR hasn't used carbs in the Cup series since 2012. If you want max power through the entire RPM range from an all motor build, EFI with ITB's is literally the only way to go. You can't beat physics and computing power with a single plane and a mechanical carb. There's just way too much variability.
@@spdcrzy nascar does not run wide open throttle start to finish. Nor road course cars, super cars ect. Pay attention to what I said. Natural aspiration or boost is irrelevant. Some guys on a tour often run an efi system because it saves on time and mistakes weighed against the small gain. If you build 2 identical engines, one with a efi and one with a properly tuned carb the carb will build more hp and tq under a load and faster than an efi. Look around here on UA-cam, there's dyno vids to prove it.
FAAAAAAAAAWK!!!!!!!!!😲😲😲😲😲😲
What are the specs?
