924 HP on a pump gas 540 is actually really impressive. Shows what a well built engine with a lightweight rod and piston and really good head flow is capable of.
It also goes to show that there is a big difference between a high performance NA engine and one meant for forced induction, considering a max effort NASCAR 6 liter engine can reach 900 unrestricted on 93. But that's what it was made for. An SMX built for NA would produce Pro Stock numbers. Especially since Steve used to do Pro Stock professionally.
@@benjamins9121 I'm sure this engine could easily do at least 1100hp n/a. Most pump gas 540 bbc are in the 750 to 850 range. Add some compression and max effort cam easy extra 100hp
@@benjamins9121 NHRA Pro stock? Nah.... SMX is the wrong configuration for Pro Stock, Pro stock is very short deck, big bore, short stroke. Also SMX does not meet pro stock rules in any way.
Love it!! Steve says to disregard the top HP number because that's a fluke because of how the dyno unloaded the engine. So he derates the run. Everyone else takes any number they can fudge and adds to it. He's the real deal!! Love the water-cooled engines, multifuel capabilities, 3 stages of injectors, nice setup.
Finally more people are starting to realize that water crossing through the head gasket is a design flaw. I have been wanting a water sealed block and water sealed cylinder head since I found out coolant went from block to head, so 13.
@Wouter Kellerman If there's no coolant flow across the head/blocked interface then it is absolutely critical that there is balanced flow from the coolant pump to the seperate cooling systems. In the early 1940s Rolls Royce was having serious cooling issues with their X-24 cylinder aero engine. They were using one coolant pump to provide coolant to each cylinder block/head (these engine used a one piece block with integral cylinder head). Problems with uneven coolant distribution led to major engine problems some of them causing losses of aircraft. The primary aircraft using the Vulture was the Avro Manchester which used two Vultures. This was redesigned with a new wing as the 4 engined Lancaster.
@@joshlewis5065 hundreds of millions of conventionally water jacketed engines in the world for over a hundred years and you think it's a flaw. You call a necessary component of longevity a flaw? That's stupid.
It is not stupid. If you don't need it, regular cross flow from block to head or head to block via the deck is great. But if you are trying to cram 60 psi or more into an engine, then you need to do things differently. This is a street strip race engine, not your average grocery getter.
That is a really cool engine Steve! I cant even imagine if you had 44 degrees from the initial load in, and an N/A cam that was bigger! This thing would rock! Just goes to show that your base engine before the boost, is totally legit.. Thanks for posting..
Love the way you think. Some people like to 10.5 cr. Then add boost not me I love shoving all that air in a big hole add plenty fuel boom make things happen. Great job SM. And crew have a happy new year’s.
I enjoy looking at engines in the combinations just as much as I do the car itself that it goes in. I think ultimately when we see a vehicle especially a custom vehicle or a race car. Our first thought that pops in our head what engine is in it how big it is how powerful it is what engine combination are we looking at as far as power adders. I think looking at these billet engines is like looking at a work of art and they don't have to be billet for me to admire it. I don't know maybe this is the gearhead in me. A lot of people say that custom cars is the paint job that makes the vehicle to me what makes the vehicle is the engine when you open that hood what is in that engine bay. It's like opening a treasure chest or opening a jewelry box full of diamonds to me it's the focal point of the vehicle.
Why do you think it will need 40 degrees? It doesn't have big domed pistons, so even with a big cam for n/a use and flat top pistons, the flame will more than likely be way too fast for a 40 degree timing. Looking at the heads and the design, if you raise the compression a bit for pump gas N/A, I doubt it will want much more than 34-35 degrees.
you know what would be fun here is putting a couple of led lights in the intake and wandering the camera lens around...maybe some smoke or a string couldn't do that with carbs.
Seems like a very smooth engine The idle is so quiet and smooth. Maybe because its in the other room? whats it sound like starting up when you are right next to it?
Gotta love it! Just think how much more power it would make with more compression and n/a cam I dont think a safe 1300 is out of the question! We kinda know what procharged and twin turbo setup's do, I'm not a nitrous guy at all but I would like to see one of these with around 572ci and a few kits with some ZOOMIES and see what happens when you throw one of Chuck Fords blowers and a big screw blower on a smx and spin the hell out of those blowers
Would you mind telling me a little about overlap for turbo usage. I don't understand using a lot of overlap for turbo usage. For street I'm thinking 0 or- overlap
Wadder in Wadder out, hot darn that's Flippen awesome this thing will haul asphalt....I'm sorry for my language... I just want to see Steve cuss once I awhile to prove he's not Mr. Rogers in disguise... lol😛
I’d love to put this in a daily driver and beat on it for 100,000 with regular maintenance, like a Toyota and see how it looks. It’s so over designed, it probably would look brand new. That’s one mean daily driver.
940 on motor with 10.5 compression!? The magic has to be those heads! You can take a 598 bbc with a badass set of brodix heads and the same 10.5 compression and still not make 940. Steve morris really figured this shit out.
Not really. He mentioned that those heads from a port standpoint are not that big. He spins a 540 to well over 8000, of course it will make power. Sure it has a "blower cam" and run pump fuel, but to do that, it's still one hell of a big lift high duration cam. The compression is not a big deal for that either. I think his philosophy is to get the rpm up with the smoothest cam possible and then do the rest with boost. If you went with big N/A 9 degree heads, and a super aggressive cam, even on 10.5 you'd make well over 1100 hp. The interesting part here is not that it makes 920 or what ever hp. The impressive part is that it runs as smoothly as it does while doing it.
Because it is ..? Name another car manufacturer that builds a 1,000 hp NA motor on pump gas that comes with a 2 year or 50k mile warranty? It has literally never been attempted before. A conventional BBC making four digits NA designed to last for years of racing at the track as well as beating the piss out of it on the street, isn't an awesome feat of engineering? No it's not a 5,000hp capable monster that we all know is the best drag and drive motor ever created, but for $30k you can buy a 632 from the same company that sells mini vans and that's not awesome? Come on maaaan!? 🤙
Not gonna lie I was expecting like 700 when he started saying it wasn’t built to be n/a and all that stuff then the fuckin thing pulls over 900.. lmao. Fuck I’d be happy

I laugh when people say "pushrod engines" are out dated.. From 1,000,000 mile taxis, to 10,000 HP top fuel dragsters, they work...
Steve your a pure champion!! That's some serious power out of a motor that's not intended to be NA and on street fuel . Amazing!!
Just SO DAMN AWESOME. Real marvel of experience went into making this !!!!!!!!! Very proud of you guys.
I am impressed with the high rpm you are able to get out of your SM engines and still have them be so reliable.
Love your TH-cam videos and Steve tech is even better, can't wait for the next one. Would be an awesome place to work.
Steve that motor is simply the best motor out. I want 2 one for my car and one too put in my living room too look at

Can’t wait to see what old Cleetus and mullet dose with a new SM big block in her. I see 6s with hardly any effort now.
Lost for word's, thanks for the info. We ran a blown Donaven alt years ago and we were always burning up pistons at 8500...
Thanks for sharing that. I've wanted to know what one made NA.
Will need the drive train that's bulletproof also Steve will have to recommend the components great looking engine
Very nice and cool motor !
I'd like to see Steve, Kevin (KSR) and Laz do a project.
I wish I could afford a 940 horse SMX n/a motor, let alone a boosted one.
The replacement for displacement is cubic money.
Would be interesting to see what you could do in a 289 cid N/A engine for aftermarket Cobra cars .
I think you took engine building to another level.My question to you is I have a 65 Mustang what can you do for me
I would like to see an experiment with that engine, N/A Cam, and 40 Deg timing on pump gas with the right tune and injectors.

Truly an engineering Marvel!
Can’t wait to run one Steve....
Beautiful engine
I want a career with you. Completely understand what you're doing
Lets car pool !
These engine would be awesome for a go fast boat with the cooling set up
But it will need a totally different cam.
Holy hell the SMX is a fucking beast!
you know what would be fun here is putting a couple of led lights in the intake and wandering the camera lens around...maybe some smoke or a string couldn't do that with carbs.
I think it's cool, love to have it in my Torino.
Plus another 2500 hp with boost.
God bless America. Yeah!
Yeah, I think that would tow a Drag Week trailer no problem.
Wow I need to win the lottery, that way you could build a engine for my boat. 😉😁😁
Steve you need to work out something with your boy Cleetus. He needs a nasty big block in Mullet just like this that he can run on pump gas.
Seems like a very smooth engine The idle is so quiet and smooth. Maybe because its in the other room? whats it sound like starting up when you are right next to it?
Very impressive

It's a 540. It will need a huge cam to make 1300 hp. That's just the nature of things.
At 70 psi on alcohol it would be adequate. Just your average 5,000 hp street engine.
Would you mind telling me a little about overlap for turbo usage. I don't understand using a lot of overlap for turbo usage. For street I'm thinking 0 or- overlap
Ever do any say 800hp dyno loads sustained to see how the temps hold? Wouldn't really matter for a car but wondering for a boat.

What I'm getting is woter is alot better than water when it comes to cooling.
Nono, not water. Steve's using "waddar" lol😀
How much can you run up the timing given the fact that it is built as a boosted motor (in this configuration) with a bit lower compression?
65rambler marlin , Build ! I maybe could cover the shipping on that engine! Lol
106hp/liter NA with pump gas and boost friendly compression? I’d buy that for a dollar.
$1 or you know $20k.

Why would he use a heli coil vs just tapping/threading the heads/block for the ports?
make Cleetus one of these bad boys!
All I want for Xmas
Are you controlling water temp with external t'stat ?
40* timing on 93 not set to kill wow. What she normaly take up top NA? Though I guess it's lower comp.
