- Quite the coincidence… The same time I start to build a Gen1 SBC 400 Karl Ellwein is also building a 400 SBC. They only difference is this old school gem is an O.E. block and made to drive anywhere. How much power will it make? Well you just got to watch the video to find out!

Update on the engine. After a month of driving the car it runs amazing. Still trying to put all the power to the ground as it spins the tires with ease. I have a set of Hoosier DOT legal bias ply tires I am about to try on it. If that doesn't get her to stick I may need to look at putting Cal-tracs on her. At 60 mph if I down shift to 3rd and floor it she lights up the tires. Crazy.. The throttle response is great. Had to go with a high dollar dual disc clutch to handle the torque and HP. In hot August weather it never got over 180 degrees. Its the best performing small block I have ever owned or driven. Super pleased with it.
Update. Still spins tires bad with the Hoosiers. Have added Caltracs and a taller gear ratio. Will see how it goes.
I was impressed with the Hoosier DR2 Drag radials after trying a couple others.
They hooked the best for me in a 2900lb car. I'm sure your running a little more hp than my stroker put out though.
@port nut Engine is in a 67 Camaro. 4 speed car with 3.73 gears.
I'll take a SBC 406 over a LS engine anytime!!!!
Best bang-for-the-buck 406 small block. I had a 64 Nova station wagon with a mild 406 with 373 gears, 3100 car for 21 yrs. I now have a ZR1 which I enjoy, but I think the Nova was more fun,stealthy sleeper!
@@howardbedford6075 nice.my c3 has a 406 with 390 gears and I can blow away chargers mustangs and new camaros NA. Love it. Skip White internal balanced 11/1
@@bbtruckin3112 i agree
@@bbtruckin3112 yes!!! I had a stock 1975 400 in a 1970 Impala Custom Coupe and I loved that power! I can only imagine the feeling of this worked 400!🤜🏿🤛🏿
Agreed beast of a engine
That's impressive torque for a 406-407 I remember years ago when Chevy came out with their 502 performance crate engine putting out 550 torque so this 400 small block doing about the same torque is very very impressive, props👍👍
Great video those AFR are worth the money
400 small block is a great motor. Makes lots of torque
400 sbc is a great all around street engine.✌️😎
Pro tip: DCR Dynamic Compression Ratio determines engine octane requirements not the SCR Static Compression Ratio.
Select the wrong camshaft for your compression and it can easily exceed 91-93 octane pump gas.
My 4.8 LS has SCR 9.72-1 and exceeds the max DCR for pump gas due to the intake valve closing a hair too soon. JD
Right you are. Its not that "compression ratio" is a bad communication. We all picture the same thing on hearing it: bdc vs tdc volume. But... compression implies work, and since there's an open system until some degrees past bdc and the piston is up the bore, I sometimes wish we all just said "volume ratio", but... not happening any time soon. Meantime, the number really just tells us roughly how early or late intake closure is - IF the builder was mindful of dcr limits.

I know your post is 2+ years old, but it caught my attention when I stumbled across this video today, and I will say you are 100% correct!
I actually ran the dynamic compression numbers based on the information they gave in the video and used the Wallace calculators and averaged the d/c for advertised and @.050 and came up with 171.40 psi of cylinder compression. The 93 octane should be able to support that just fine.
Well thought out combination-
I can definitely see why this engine made the kind of torque and horsepower that it did.
I’m currently building something similar and these are the kind of numbers that I hope to make with my 400 sbc.
I’m going to try and screen shot my dyno sheet from my 11:1 400
I’d really love to know the specs on everything used for this build I know the heads are AFR 195cc but I’d love to know much more!🙏🏾 ty
I will love for more information on this motor
Or can u send me your email for more details
Well shit. You beat my 400 sbc.
That thing pulls hard!
I have my original 400 sb in my 71 chevelle 🤘🏻
Damn that thing is a brute, more torque than a lot of pump gas big blocks I’ve seen. 👍🏻
It was purpose designed for torque & responsiveness for the street. I think Karl nailed it.
@@wreckanchor
Agreed 👍🏻
Had a SBC discussion with the guys at my local Carquest the other day. They were all in a "383". Then they asked my input. I politely said why do want a 383 when you can build a 406, 500+ torque/HP on pump gas is not that hard. I even mentioned some AFR 195's, similar compression, and similar cam ran here. It's a no brainer in my opinion and this video proves my point. They seemed to agree after our short discussion. I will show them this video.
Karl, I know this is a little late, but would it be possible to see the entire dyno graph for this engine??
Yes I second that comment! I'll take my old 406 over anything today! Ls maybe unless I had access to a LSX cast iron block? BUT mine with 12.25:1 comp would Love 38 total advance all day long!
If I worked at a shop that had a dyno the boss would have a helluva time making me go home!😁
Well, that was a refreshing way to start the morning! Viagra? Psh!
Talk about fantastic street engine ! Great and informative video as well
Hard to find.. 400sb
This came up on my feed today ..
I've been running a 406 in my '69 Chevelle since '98.
Pat Musi built, driven to Boston, Mooresville NC, Wildwood NJ and Ocean City MD many, many times, still runs great, makes tons of torque and never had any major issues. Definitely made the right choice when I chose to have this built.
What kind of transmission are you running
@@mrmurdock2u247 th350 with a gear vendor unit.
Solid street engine
Karl is the man us lt1 guys are proud to have him.
good stuff great numbers for a small cam .. great engine for the street
Anyway 667hp/590tq
What parts did you use? Awesome!
Dart SHP 4.125”
Eagle 4340 3.75”
Ross 2 valve flat top
6.125” Scat 4340
Mike Jones solid roller
Afr 210 heads
Crower 1.6 shaft rocker
Mamba lifter
11:1
HVH hand ported by me
AED 850
If you don't mind i'm curious what cam you used in this build? Also what heads, my engine is not far from yours and i'm just trying to compare how we're making power differently. My engine is primarily for street use with 10.85 to 1, some trips to the track anticipated.
@@waynetessier3058 Your asking about Philips engine or the one in this video?
@@wreckanchor ; I was asking regarding Phillips engine. I would be very happy with your engine build as my full roller 383 is very similar with 200 cc eddy Etec heads, if I were to do it again I would trade my heads for the AFR 195's. The reason I was asking about Phillips engine is my 10.7 to 1 399ci. 1st. gen is putting out 641 hp. and 560 ft lbs. on 89 pump gas.
I love dyno room time! used to be my favorite part of being an engine builder/rebuilder. Got to work on some nice dyno room projects. great time.
Nice to see the afr 195 heads will support that kind of power.
Subscribed. Had no idea the LTx icon builder had a YT channel. Can’t wait to dig in…
Have my eyes on a 400 sbc.
If we can make a deal, it's going in an 84 Camaro.
Gonna be rowdy
Love this video I only build SB 400s with a custom 282 grind. Sounds and runs so good.
Nice bro! Now just add some laughing gas 💪🏻
These are my specialty 😂 Ls is just junk lol 😂
Nice I built the same motor. Only I used 220 CNC ported flotek heads .622 lift and 10.98/1 compression internal balanced with all forged internals 292 cam. I never dynoed it so this gives me a good guess that I'm 550 plus. Ty!
Hey Sean it's John from tiktok and people think sbc are a thing of the past because they don't have any fucking clue what they're talking about lol I'll take my sbc over a LS any day
@@jonathanlawson4667 hell yeah. I want to build me a 18° headed big cube sbc someday.
Sounds like a sweet build.
@chriswells1440 still building it. In ptimer finally
Only 1 wasp was harmed in the making of this film ... 🤣🤣🤣
Nice build 👍🏽 thanks for sharing this video with us
What is the torque curve down low as I am replacing a 350 vortec and was thinking to use a 400 block for torque-I’m also not opposed to a few hundred extra horsepower as well
My engine is similar but with Edelbrock pro-flo 4 and I'm at 443TQ at 2500. I peak at 517 at 4500 and end at 442 at 5800. Its a nice flat load of torque. Torque all the time. LOL. I did hit 501hp at 5600.
How about a budget 400 build? Something like a stock shortblock with a hydraulic flat tappet cam and say fuelly heads and such.Something your average working man can afford.Not a $10.000 or more custom drag engine.
That's not a 10k motor for sure. I did not built it but it is a stock block.
I had a 400 sbc with flat top pistons and GM Vortec heads, flat tappet hyd cam and the same intake manifold and it made 423 hp @ 5500 rpm and 520 ft pounds of torque. The cam is a fairly mild comp cams 280H. The 400 sbc is a torque monster and you dont need to rev it high to get that power. Avg man can build this engine
Would like see the run down of parts used. That's big block 454 hp/tq numbers for a street engine
what crank/rods/were in the engine, internal or what balanced,, solid cam, or hyd, what block .old junkyard 400 or a aftermarket dart
Forged Calies crank, Compstar forged H beam rods, Forged Mahle pistons, balanced rotating assembly, GM block bored .030 over, Hyd roller cam.
It would be interesting to switch to a tall singl eplane intake, and see what numbers it comes up with (?)
Wow what a little screamer! Fantastic job on the combination..You guys rock..
Sure like to have a engine in my 91 2500 for towing my 28 ' race car trailer, I bet this would get the job done to and from the track ✅
If you can't build power from a sbc you can't build engines.people who can't build always buy
The wasp just wanted to get a look at the power and torque curves...
If you do the math, you will see the so called 400 is actually 401 cubic inches. Just like the math on a 350 Pontiac is 354 cubic inches.
I have a 400 block, any advice on the best heads ? I would like to put the engine in a truck , any advice on keeping the engine kool and helping longevity? the truck has 4:56 gears Thanks
The old timers are starting to let go of some of 400 blocks they’ve been hoarding for years. I recently picked up a nice 30 over 509 casting.
I’ve always told several friends that the 400 small block is hard to beat. Flat tops and a solid lift cam with decent heads and you got a runner!
My buddy has one of these in his 67 Camaro with turbo 350 and it has no traction at all on the street,even with drag radials. The thing is that the hyd cam kit to run a roller in an older sbc is 1400 bucks. That is more than I paid for my very good running 6.0 and 4lL80e. A much bigger than stock cam and some valve springs are about all it will take to get close to that 500 hp for way less than half of what it cost to build a 406.
Back in the day I cured traction issues on my similarly powered 67 Camaro by putting a set of 275/60/15 drag radials on stock 15x7 rally wheels, bolt in sub frame connectors and South Side Machine lift bars. A pair of Calvert/ Lakewood 90/10 front drag shocks would also help.
I love those old holley intakes. They're great street intakes
They are the best dual plane I think. Especialy when you use a 1 inch spacer with them and a bigger carb than you think you need. lol
@@wreckanchor You'll have to feather foot your Camaro now with this low end torque.
@@EllweinEngines I know. I am wondering if the tires will hold it. Should have the car back in a week will let you know how it runs.
What's the part number on the intake? I'm in the process of a similar build of a 406 but was thinking of a Victor Jr.Dont know if I should go a duel plane or open plane..Can't believe the HP your sbc produces..Great combination guys!!
How about a torquey 400 build that will work with a TBI and be able to pass smog. Not all of us need an engine that will rev to 7k, just need better pulling power for our trucks
Dude those are great numbers!
Can’t wait till my 60 over 400 is complete.

I built a 406ci for my 86 squarebody with 10:1cr,Promaxx 200cc aluminum heads,a 480/480 lift with 110* cam (small cam /had a vortec topend before got heads) -12cc dish 4VR pistons with 5.7 rods,performed air gap intake,Holley dual line pumper 750, oil valley plugged off,long tubes headers,running a 10” 3800 street/strip stall converter …wanting 500hp+ …straight beast on the roads!! Gonna chassis Dyno this summer and fiqure out RWHP so I know what motor is around hp
I got a video of motor running on my page
You can't say "engine masters" on your channel? Mighty strange, mighty strange.
Would y’all please share the specs for this build please.
I built a similar motor,stock 400 block (509) with those same AFR 195 heads. Chris Straub hydraulic roller cam .547 INT .510 EXH , Eagle crank and rods 6 inch, edelbrock RPM air gap intake, holly 750 dp. It’s in my 65 chevelle. Car goes like hell. In the process of installing and edelbrock pro flow 4 right now. Hopefully it runs the same or better. Great build guys thanks for the video.
I have a 406 with a pro-flo 4. The engine is not installed in car yet (sitting on engine stand) but has been on the dyno. 501.1hp @ 5600 and 517 hp @ 4500. I think there is more there. My engine has a slightly smaller cam and running 1.5 rockers vs 1.6 like in this build. Same AFR heads. Full forged assembly. My compression is 10.7 We didn't play around with it a lot so I think it needs a little more tuning. Going to use the chassis dyno once I get it installed. The engine builder said it was a breeze to set up. He normally uses Holley FI but liked the Edelbrock ease of insulation. 406 torque curve is flat and pretty. The cam idles nice. Should be a great engine for my '89 IROC.
That much lift with only 10.3.1 and 195s. leaving easy power gains on the table there with a few engine parts choices
what the fuck do you know? you know nothing… those heads keep increasing in flow past .550”-600” lift. idiot.
Nice build! What is the music starting at 1:29?
Wow that's awesome 👍👍
407? Always thought real gear heads rounded down, =406
Yeah. lol
When I build my 400 and stuck in a 4 speed manual K5 1984 No one believed me when i said i don't need nitrous. She is going back together this spring. And doing alot more this time.
@wreckanchor I know this video was posted two and a half years ago, but I wish I could tell what intake manifold is on it. I can't quite read what is cast into it.
I forget myself but I would put a RPM air gap on a motor like that.
I need 3 of those engines right now
You can get 500+ HP with 400 cubes, any mid 230s @.050 cam and 9.75 compression on 89 octane. I've done it, smedings done it, blueprint done it etc...
Love the dual plane and 550 ft lbs!
Yep. lol bad ass little intake.
This thing is Meaty! I bet in something lightish 3500 or less at that it would scare most people to death to drive! I would do a 70 Nova with a stick shift! 355 gear. Of course that's a window shopper build.
What’s the internals, I’m building a 406 sbc. I’m using stock crank, flat top pistons, and an edelbrock performer rpm intake. What cylinder heads and cam should I run? Daily driver so needs to be street able but have some power to it
On pull number 5, why do you think the power was bouncing around from 5500-6000 rpm? Valve float maybe?
Why would you not take it up on a timing more it was gaining horsepower I think that motor is good for like 42° initial timing I think it would have put out more power and you did not see what RPM you were revving the engine to to acquire that horsepower for me I need to know the RPMs and the torque curve at the precise RPMs otherwise I would not be interested in further washing your channel
wish i still had my mighty mouse 327/375 hp w/202fi heads and a ramjet fuelinjection unit after tweeking/tunig 425 hp.rat killer!!!!
I've been snagging up 400's for a while now. Currently I have 6. 5 are untouched and still stock bores. I built one 406. LOVE IT!
Watching this, I think I know what direction the next one will take. 😁
What AFR heads and what Holley intake is that and what carburetor?
195cc and 850 xp I am not sure about the intake but its nothing special.
Looks to be Holley Street Dominator 300-36. It’s discontinued. Equivalent to the Edelbrock Performer Rpm
@@TPVPRO The intake is a Holley 300-36. Best dual plane intake ever made for the SBC in my opinion. Close copy of the 69 z28 Winters intake. Has the biggest runners and plenum volume of all the aftermarket dual plane intakes that I am aware of. I have them on a few cars and they always perform well. I typically add a 1 inch spacer. They out perform the Edelbrock AIr Gaps and performers by a noticable difference.
@@kristjanstefansson2765Correct. Best dual plane sbc intake IMHO.
Boneshaker I was running the Edelbrock air gap on my 67 L30 327 but I wanted a vintage look as it's in my 57 Gasser. So I replaced it with that 69 Z28 manifold you mentioned (eBay .. not cheap) and it seems to run as strong or stronger!
Do you think the loose rockers are a result of lifters failing to stay pumped up? Are they roller lifters? I am having issues with my 385 Lt1, Gen2, rockers.
I didnt think you where going to make any hp/Tq at 6000 rpms the those tiny heads on a sbc 400 engine afr 195 heads are excellent when put on a sbc 350 or smaller engine they hit a choke point in the cylinder hezd at the push rod area
Holy Christ, that damper!!!!
Engine tuckers?
A slightly larger cam and a set of 220 AFR's would make this thing a demon!!
That big damper was expensive. lol
And a single plane.
Already had a 406 with 220 afr's. This engine was built specifically for torque and street responsivness.
Get some stud girdles on that beast.could have went a lil higher on compression
Does this motor have a hydrolic camshaft ?
Yes
We use 98 BP petrol ⛽ in australia why do you.all.use 91 or 93
have an old 400 sbc in my garage and some vortex head what do you think
Use a stethoscope in the dyno room and every sound you investigate will be clear, clear, clear. Great ears on those gentlemen.
What intake manifold are you guys using? Nice build
Awesome engine! Music is maddd corny 🌽!!🤣
I built a 421 sbc and was also running the AFR aluminum 227 heads!! Dart block, fully forged internals, and full roller set up!! Mine definitely needed more air so we installed a 1” carb spacer and was able to gain another 30 HP!!! I was able to run it on a dyno to get everything broke in before installing into my vehicle!! We was just shy of hitting 700HP but the torque numbers were also amazing across the whole board!!! Definitely one of my best builds for sure!!!
My old man used to build 421 back in early 90s for late model dirt cars made over 700hp would rev to 9k
Um not so sure about the loose rocker that could have caused a lot of problems
400 the red haired stepchild. love it
At what RPM? combustion chamber volume?..valve size? flat or pop ups? compression ratio?..early or late exhaust opening and how long(degrees)?..thanks 45 G town Texas
All that is discussed in the video if you listen close. has 10to 1 comp ratio. 2.05 intake valves AFR heads, Forged Calies crank, Compstar forged H beam rods, Forged Mahle pistons, balanced rotating assembly, GM block bored .030 over, Hyd roller cam.
400sb one chevys over looked engines
hi AFR street or Competition heads . part no. ?? 2.05 or 2.08 valve. small chamber so must use a dish piston ... 64cc , 401, Flat top =11.3 cr
Carby size , carb spacer , step headers , maybe the inlet manifold ? all these would give 20-25xtra HP
seen 395 [stroker 350] with 230/236 weiand 7530 1 3/4 primaries do 495 hp
AFR PART #: 1040 2.05 valves, 65cc chamber, 850 cfm Holley, 1 inch spacer. Dual plane Holley 300-36 intake. Dynatech Headers SBC 1-5/8-1-3/4 Stainless With 3″ Reducer. Car has a custom bent 3 inch exhaust front to back.
Between his silly gloves and his not even knowing the universally-accepted displacement of a 4.155 bore sbc he’s ridiculous. If he’d put some better heads on he’d have seen some power.
Was purpose built with the 195 AFR heads for street torque and responsiveness. I decided on the heads not the builder, who is amaazing by the way. I already have the same engine with AFR 210 heads built for another project.
Wat are the headers called again?
The wasp project!
What cam
Starts at 0:53
What are the cam specs? Awesome build!!👍👍👍
Gross Lift: .548/.548 but with a 1.6 rocker the lift was .584 / .584 Duration @ .050: 238/246 110 lobe sep.
Why didn’t y’all show us what you did to get that much HP
What do you want to know? 406 cubic inch factory GM 400 block. Calies forged crank, forged rods, and pistons. Just over 10to1 compression, hydraulic roller cam. AFR 195 heads, Holley 300-36 intake, Holley 850 carb. I think a huge part of this engines performance is due to the efforts of the engine builder Karl Ellwein. Search his videos here on youtube and you will see how super particular he is in everything he builds. Everything he builds seems to over achieve power wise. I dove 5 hours each way just to have this man build this engine for me. Would do it again in a minute.
would it be better with a single plane and a 750?
More HP at higher rpm but less torque i would think. 750 isnt enough for it. This dyno run it has a 850 xp on it.
Great work!!!!
Any details on your heads your willing to share? I’m building a 406 but I’m Undecided on what heads to use since I’m building a streetcar
Not my setup but it's a AFR race ready 195cc SBC head. You for sure go 210 that's what is on my setup
ua-cam.com/video/EOvNM_q0mgI/v-deo.html
Get the head just before the ones you have to run offset rocker arms for them. Can't remember but I think they are 220's any horsepower you loose below 3500 you will find it plus some at 6500-6800
Good show #!!!
Where did you get the heads from?
Summit Racing part number 1040 AFR's. 2.05 intake valves, angle plug, 65cc chamber.
