It's why i tell people who got "LS ON THE BRAIN" that there is no need in it.... You see here a old school SBC built and boosted equally will make just as much... If you want the "LS" stuff for economy etc, you can get a computer system like Holley etc in the video and run LS electronic son a SBC..

@@sstevocamaro Not for factory serpentine type setups... The 87up ones. Plenty of people have them.. Yet they don't make a supercharger for them.. Procharger and Vortech does, that's it to my knowledge for centrifugal types anyways.
@@ICONBADGTA cost vs power ratio. When you see that dart block alone costs about 8 grand. Thats why people hype LS’s so much. Most people don’t have the knowledge or the money to build a rival sbc vs an ls. I love them both, depends on the application for me really.
@@ICONBADGTA hey man, I’ve seen so many videos lately of how well the small block Chevy still does. I just got myself a third gen (305 😢) Camaro and had the dream of LS swapping it because that’s what everyone said to do. After watching all this stuff and reading more it seems that building a mild SBC ~350hp would be just as good. It also seems like building a small block Chevy would be about 100 times easier and cheaper than trying to get the LS in with all of the fuel needs, wiring needs, bracketry, and tuning. Also, I probably wouldn’t need a brand new transmission with the SBC. Am I thinking clearly here?

I real like the LS for reliability…. I have watched you UA-camrs go two seasons on an LS without even a refresh with zero issues. Hell I think Billy the kid went through like 7 motors between his S10 and nova and Jake had the same LS is his falcon for years and was winning. That being said it all looks expensive 😂😂😂
The LS wasn't that bad. It's way cheaper than the SBC. If you want to see the building of it . Then check out muscle car custom garage. Awesome grassroots building and racing
I would be cool if the SBC in the car could grab outside air and having a ram effect. Maybe even a aluminum plate above the headers to even keep more heat off the supercharger. Thanks for the video!
My Dad and I love SBC engines, great video Steve. Can't wait to to see the SBC brodex your building for us, just finished up with his Wing last weekend, tons of Down force tested over 500lbs at 50mph

Ole 383 been around for 30+ years or more, still kicking but, I have always wanted the 3.625 stroke 4.030 bore, with 6.0" rod, should do great, the 377 has been kicking but since the 70s, along with this 383, old school kicking arss, love it!
I’ve had a ton of small blocks. Loved every one of them, especially the 300 hp 327 in my ‘63 Impala. Had it balanced and blueprinted - ran like a Swiss watch.
If you want to see the build of that LS, please check out the channel for part 1 and part 2 to get an idea. You don't have to spend the money in c&c ls3 heads. You can run stock ones to save money and a stock LS3 intake. And it will still make really good power.
Hi steve I am following you from Belgium ,Europe and a I am now minus validen at now with a wheelchair person butt i was before that busy like 30 years mechanic for trucks and heavy machinery and by hobby looking ad diesels to tickle them and I became at your site for turbo charging and yes man yo are for my as well a true man and speak really honest about these things thanks man yo are doing fantastic work 🎉🎉🎉🎉🎉
When you have a sharp edge on your inlet duct opening, the sharp edge makes your opening smaller due to the turbulence that sharp edge creates. Colder air is more dense, having more air molecules per volume, thus creating more reaction when ignited with fuel.
Hey Steve, you're gaining power from the bell because you have created a Venturi which causes there to be lower pressure at the inlet, speeding up the air coming in as well as creating the opportunity for more laminar or smoother inlet air flow. When it comes to the supercharger increase in horsepower between that and changing pulleys as you change pulleys you're going to have a linear increase in power per pound of boost until you reach the limits of the compressor. You'll notice that you gained more power per pound of boost with a comparable compressor on a turbo. Why? Because you don't have the parasitic loss from the transmission. As you change to smaller pulleys, you increase the parasitic loss along with it. When you gain boost from helping the air get into the blower or creating a cooler, denser air charge, you'll notice that the increase in boost yields more power per pound of boost by far partly because you're gaining boost without increasing parasitic losses.
@39:26.... It`s cool to seen purple spot moving inside the map while you play with your timeline inside the second window. Advice : Have you considerate to plug a second monitor on your laptop and use in extend mode? Like this you can have both of your windows maximized instead to be overlapped. It's common trick for programmer... You run your program in one screen and the other side you can see your code.
Old school tuning method when switch switch racecgas turn up the boost lean it out and add timing till it just melts the electrode....then back her down a touch.👍😂
In the late 60's 110 octane was available in California at Chevron as Custom White Pump. That included lead before the ban. The hottest engines were 12:1 N A
Great video fellas. The business is in good hands with Kyle. He's got a cool head. I really wish I could have you guys build me a SBC. I can't swing it but would if I could. 👍
I've only owned 1 turbo car in my lifetime and keep considering building a second one. My Dad was a big nitrous guy... Never liked that much. Back in the 80's I had to rebuild his engine a LOT! Today, I have 2 old school 460's that pump out between 300 (stock) and 500 (slightly modified) and both are plenty good with me. Just picked up a V6 F150 that's pumping out 300HP.... more than I'll ever need out of that truck. Maybe some day, I'll add a sushi slicer to it, but not right now... thanks for the comparison!
The additional 2 psi of boost also added more parasitic loss and you have reduced the vacuum in front of the compressor wheel so reducing the parasitic loss on the charger as it would be easier to spin. I think it's a combined result of an extra 1psi of boost and less parasitic loss giving 55hp vs 2 psi of boost and more parasitic loss giving 50hp. It's more the air coming in from the side or behind the compressor hitting the air coming in straight and causing massive turbulance. The bell acts like a nice smooth on ramp on to a highway rather than just being a T junction with a highway.
Nice analogy with the highway entrance, it also allows denser air getting some cooler air from areas away from the header. Even with the header covered its still probably well above ambient in that area.
The videos that you make with scene changes are just great. Will this one be better. Will dad's 383 beat the LS. The suspense is good. Love all the tech talk re air fuel ratio and timing too. Thanks. Rex in NZ.
Steve get a rubber elbow for the inlet size and aim it upwards and slips the over a piece of metal tube in the new inlet and then you’ll have the cool air. Plus way cheaper than header wrap
Great video. I would love for you to do a video on class legal turbos. There are a couple of wild things happening in our local series and I'd love to see you prove out displacement vs class legal turbo and make it make sense!
@@bigboreracing356 I sold my LS7 in 2016. If you look at my profile at the very bottom is an old video of it. 441ci 13.5:1 Rex Hutchinson built E85 built TR6060. Made well over 600whp naturally aspirated and ran bottom 10s in the mid 130s on a drag radial. Had I been able to run that car on a Northeast track like Atco or MIR it would’ve ran in the high 9s. Had I been willing to cut the hood and run a Holley HiRam it would’ve made significantly more power. I never had a problem with a N/A SBC.
12.5:1 NA motors could live on Chevron Custom White Pump in the late 60's. That was before the lead ban, at least in California. The next option was Aviation gas from the airport.
At 18:34 when the belt smokes against the coolant hose did the tensioner adjust that much difference to maintain tension? To understand serpentine drive belt systems does require learning at least one more language.
Alot of people dont understand boost is mearly a measurement of restriction, bell = better flow. so not necessarily more boost but easier flow of air into an engine which means more power.
I loathe serpentine belt driven blowers, the moment you go to pulley down the blower to make some boost you know upper RPM slippage is just around the corner. At least this kit has a well designed guide/tensioner setup to maximize the belt wrap around the blower pulley.
Throwing a procharger on my sbc would make my (current) dream combo. Some day, I'll either swap the pistons out of mine and slap an F2 on it, or if I win the lotto, have SME build something ridiculous 🇺🇲✊️
I think there's a opening here for a new video. Maybe you should somehow capture the air in a program that shows how that Bell makes a big difference visually speaking
hey steve, could it be a tech tip video where you show the difference with radius inlet and no radius, maybe show it with some smoke or something? would be cool to see
That's not just efficiency. You're not only increasing the boost you're changing the air density. That's why the horsepower levels change regardless of the boost level.
F1A-94 likes to spin well over the max rating to make best power. The efficiency spot you are talking about is just starting to be tickled at 74k rpm. If you aren't going to overspin, an F1A-94 isn't a great blower choice, as they really want RPM. On serpentine setups allowing for a little belt slip, we pulley them for 80k-82k for max power. It'll make 1400whp+ through a manual LS on a hub dyno like yours. That's with a flex fuel friendly compression ratio. The 94 will live a good while at that rpm but definitely not as long as it will at 74k. Fine for anything that isn't constant rpm like a boat though. The P1-X, D1-X, F1A-94, and F1X all want to be spun hard. The older impeller designs not so much.
Steve, one axis, two axes. Axises is not a word. ;) Instead of breathing out of a staw, what about breathing out of a funnel? Air can be compressed, so putting a big radius inlet at the big end of a funnel where more cold and dense air exist might be a solution.
if only there were giant hose clamps to hold the composite bell on the charger inlet. (edit. lol spoke too soon, shortly after clamp appears) wonder how a velocity stack and larger bell end would work. (not practical on vehicles though)
All of my buddy’s Always trash talk my sbc! But my gm604 has been so reliable and I beat the daylights out of it in my s10. I know 400 hp is garbage to real racing… but I’m working towards 1000
Interesting video I am a social person would that inlet bell work on a carburetor to suck in more air with a 671 supercharger just wondering 🤔 but very cool video...keep living the dream ✨️
Next year build. What high revving, wide torque v8 engine would you put in Euro drifter? (internals and turbos) Have to be in 1500 to 2000hp range.Going to be in BMW f22/23 coupe chassis.
@KingJT80 if you are a competent tuner or have a competent tuner, holding down 1200whp (manual or locked auto) on an LS is a non-issue. At that level, tuning or an unrelated mechanical failure is pretty much the only reason for it knocking a gasket out. People who have trouble are the ones piling too much power in at low RPM.
@@andrewwilliamson3513 or the lesser amount of head bolts. this is why people move to the different heads on LS for the clamp force. SBCs actually have a slight advantage here
Very different builds. Budget LS with a 84mm Torqstorm vs. a high dollar Gen 1 SBC with a 94mm Procharger. Quite a bit of difference in cubic dollars. Still fun to see what they can do.
@@taptoretry7335 Not even close. LS still running stock crank, factory block, factory lifters, factory heads with a $1K CNC port job, probably factory rockers. ZERO chance that the cost to build these two engines is REMOTELY close to one another. I build engines. I'm well aware of the cost differences. The gen 1 probably has more in the block and heads than the whole gen 3 build.
@@BigMikesGarage the block maybe but not the heads so much. you dont need some trick kick ass head to do what theyre doing here. but yeah an aluminum block is pricey def more than any factory LS but its also making a bit more power and can be leaned on much harder
@@KingJT80 The Brodix heads on that gen 1 are $3K new. There are no factory GM gen 1 heads that flow anywhere near as good as a factory gen 3 head. I never said the gen 1 wasn't a nice, quality piece. My point was that they are comparing apples and oranges. A high dollar, high quality parts gen 1 build vs a budget built gen 3 engine. The gen 1 is certainly a more capable build.

@@bigboreracing356 I sold my LS7 in 2016. If you look at my profile at the very bottom is an old video of it. 441ci 13.5:1 Rex Hutchinson built E85 built TR6060. Made well over 600whp naturally aspirated and ran bottom 10s in the mid 130s on a drag radial. Had I been able to run that car on a Northeast track like Atco or MIR it would’ve ran in the high 9s. Had I been willing to cut the hood and run a Holley HiRam it would’ve made significantly more power. I never had a problem with a N/A SBC.
Cool episode of building horsepower.
Gotta add, cute thumb nail paint. 👌
12.5:1 NA motors could live on Chevron Custom White Pump in the late 60's. That was before the lead ban, at least in California. The next option was Aviation gas from the airport.
At 18:34 when the belt smokes against the coolant hose did the tensioner adjust that much difference to maintain tension?
To understand serpentine drive belt systems does require learning at least one more language.
There was just too much slop in the belt. It stopped the belt slivage on the blower but the tensioner had to move so far that it hit the radiator hose
Alot of people dont understand boost is mearly a measurement of restriction, bell = better flow. so not necessarily more boost but easier flow of air into an engine which means more power.
air travels faster when you eliminate shear angles. velocity stacks eliminate shear angle, and change its sound tone.
I loathe serpentine belt driven blowers, the moment you go to pulley down the blower to make some boost you know upper RPM slippage is just around the corner. At least this kit has a well designed guide/tensioner setup to maximize the belt wrap around the blower pulley.
Wonderful vid and information. Again
The air is having cavitation problems like water has around propellers . Its a lot easier to see that problem in water .
Love your content! Would like to say i prefer Kyle's style of brief discution of the computor data.
Tanks professor. Great class today!
Throwing a procharger on my sbc would make my (current) dream combo. Some day, I'll either swap the pistons out of mine and slap an F2 on it, or if I win the lotto, have SME build something ridiculous 🇺🇲✊️
You make informative videos. You answer most topics in a timely manner. extremely thought provoking. Thank you
I think there's a opening here for a new video. Maybe you should somehow capture the air in a program that shows how that Bell makes a big difference visually speaking
This video has just doubled my excitement for my Your Dyno setup showing up this week. Can't wait to get my dyno going, it's been down way too long.
Was steve trying for the no-bell prise ?
NOOOOOOOOOOOOOOOO
;-p
6:40 Wow that was quiet AF for 859hp!!! 😮
I learnt alot from this. Great video Steve and Kyle.
I'm seriously overwhelmed, all I hear is bla bla bla, boost, power air flow, bla bla bla
Right on guys!! Caught a funny screenshot by complete accident...at 0:52 sec...wow. Who's calling chicken..who's got it..!! 🐔🤣
long live the 383- God's engine. LOL
Have you done a video on reading plugs? I am interested on what you see on plugs after pulls.
Should we start a GFM for Them..? I mean they only got ONE stool...😅😅
Outstanding content!
hey steve, could it be a tech tip video where you show the difference with radius inlet and no radius, maybe show it with some smoke or something? would be cool to see
Put that SBC on Q16 and i bet you pick up 50hp
Great job guys!
24:00 it's called "shaping the charge"
That's not just efficiency. You're not only increasing the boost you're changing the air density. That's why the horsepower levels change regardless of the boost level.
Love your videos. regular TV is for suckers!!!!!
Can’t lie, I was just looking at the guys arms the the whole time😂
@@Mattscalf thanks 😂
As Steve might say, he has "Billy bad boy arms"
💪💪 Boss
Steve you have just become a hero for every Chevy orange bleeding SBC guy in the world 😂
F1A-94 likes to spin well over the max rating to make best power. The efficiency spot you are talking about is just starting to be tickled at 74k rpm. If you aren't going to overspin, an F1A-94 isn't a great blower choice, as they really want RPM. On serpentine setups allowing for a little belt slip, we pulley them for 80k-82k for max power. It'll make 1400whp+ through a manual LS on a hub dyno like yours. That's with a flex fuel friendly compression ratio. The 94 will live a good while at that rpm but definitely not as long as it will at 74k. Fine for anything that isn't constant rpm like a boat though. The P1-X, D1-X, F1A-94, and F1X all want to be spun hard. The older impeller designs not so much.
With low compression, why not try VP105?
Be interested to see what issues there would be on the twin opposed turbos you ran the other week both sucking in the same area 12inches apart 👍
Thanks for all the great information, I need more timing!
Steve, one axis, two axes. Axises is not a word. ;) Instead of breathing out of a staw, what about breathing out of a funnel? Air can be compressed, so putting a big radius inlet at the big end of a funnel where more cold and dense air exist might be a solution.
Axes is the plural of axis.
@@joecook3223one is singular, two is plural, isn't it? Axises is not a neologism.
@@dyoutubechannel8218 sorry i had a case of the stupid and didn't read your comment properly. Just act like I was never here
Great content thanks for sharing
SBC, FTW hard to believe they came out with them in 1955.
I’ve had a bunch of them. Always liked the 300 hp 327s the best.
Small block are my favorite they can rev to the moon with the correct cam
A Shaw Strength and McFarland Fabrication t-shirt?! Those guys know the deal!!
Thank you sir. I was curious if anybody would know that it's a Shaw t-shirt. Good eyes
if only there were giant hose clamps to hold the composite bell on the charger inlet. (edit. lol spoke too soon, shortly after clamp appears)
wonder how a velocity stack and larger bell end would work. (not practical on vehicles though)
All of my buddy’s Always trash talk my sbc! But my gm604 has been so reliable and I beat the daylights out of it in my s10. I know 400 hp is garbage to real racing… but I’m working towards 1000
Anyone who trash-talks SBCs shouldn’t be in the hobby.
Interesting video I am a social person would that inlet bell work on a carburetor to suck in more air with a 671 supercharger just wondering 🤔 but very cool video...keep living the dream ✨️
Next year build. What high revving, wide torque v8 engine would you put in Euro drifter? (internals and turbos) Have to be in 1500 to 2000hp range.Going to be in BMW f22/23 coupe chassis.
The trick is keeping head gaskets in the LS when you get around 1000-1200hp.
No trick .
@@Im_Old_Gregg it's more like 1200whp+, or 1500bhp for most street engines. Race car guys are holding down 1600whp++ with stock casting 4 bolt heads.
@@andrewwilliamson3513 one of those situations of just because you can, doesn't mean you should
@KingJT80 if you are a competent tuner or have a competent tuner, holding down 1200whp (manual or locked auto) on an LS is a non-issue. At that level, tuning or an unrelated mechanical failure is pretty much the only reason for it knocking a gasket out. People who have trouble are the ones piling too much power in at low RPM.
@@andrewwilliamson3513 or the lesser amount of head bolts. this is why people move to the different heads on LS for the clamp force. SBCs actually have a slight advantage here
Very different builds. Budget LS with a 84mm Torqstorm vs. a high dollar Gen 1 SBC with a 94mm Procharger. Quite a bit of difference in cubic dollars. Still fun to see what they can do.
You definitely have not priced out the two. The price point is almost identical besides the blocks…
@@taptoretry7335 Not even close. LS still running stock crank, factory block, factory lifters, factory heads with a $1K CNC port job, probably factory rockers. ZERO chance that the cost to build these two engines is REMOTELY close to one another. I build engines. I'm well aware of the cost differences. The gen 1 probably has more in the block and heads than the whole gen 3 build.
@@BigMikesGarage the block maybe but not the heads so much. you dont need some trick kick ass head to do what theyre doing here. but yeah an aluminum block is pricey def more than any factory LS
but its also making a bit more power and can be leaned on much harder
@@BigMikesGarage you don’t build anything
@@KingJT80 The Brodix heads on that gen 1 are $3K new. There are no factory GM gen 1 heads that flow anywhere near as good as a factory gen 3 head. I never said the gen 1 wasn't a nice, quality piece. My point was that they are comparing apples and oranges. A high dollar, high quality parts gen 1 build vs a budget built gen 3 engine. The gen 1 is certainly a more capable build.
