Real World Numbers! Dyno 400 vs. Dyno 440
ฝัง
- เผยแพร่เมื่อ 16 มิ.ย. 2024
- I have built and tested two excellent street big block mopar engines on my channel. I figured this would be the perfect opportunity to compare these two engines and their performances. Both engines were tested on the same dyno at Kuntz and Company, in Arkadelphia Arkansas.
Both engines were machined by @edsmachine93 in Rogers Arkansas.

The engine specs are quickly listed and described in this video, and both are shown in the many build videos of each.

The numbers speak for themselves. Thanks Joe.
That’s the truth!
I like both builds Joe.
I know where the potential is in both engines.
The 448 is a solid flat curve torque potential for a big B Body like the charger for which it was intended.
The picture you showed of the E Street heads was an unmodified chamber.
Heads were heavily reworked.
The 440 with the TrickFlow 240's was limited by the intake choice and carb size.
Just my opinion.
However, at the end of the day, both engines performed better than other top shop similar builds.
I think both engines are good.
And certainly not the first and last I ever machined.
Work in progress and building a better mouse trap.
And have to remember, reliability and performance combined.
Neither engines were drag race engines.
Were for street cars and the occasional strip competition.
Most Mopar fans would love to have either engine in their cars and trucks.
Thanks for sharing.
Have a good evening.👍
Thanks Ed. There’s a lot to be said and was proved by both these builds. The big consideration is that these are nice street engines. Wait until they see a race build!
nice comparison! Shows there are opportunities laying under many hoods! Speaking as a realist and not as a fan..... I will say, I like all 3 engines. But if I was going to build some HP, like North of 800 hp, the gen III block may be stronger as cast than the other 2 in my opinion. And also shows that it takes some decent heads, cam, and pistons in a BB to run with a Scat Pack 6.4 .......
Thanks Tim! I need to double check on the prices of the swap computer and harness kits for the Gen 3. It’s definitely getting easier, but everything is gaining expense 💰
@@JustMoparJoebe nice to be able to get a distributor and carburetor with single plug heads for the Gen tree Hemi so it would not need a computer to get it running
Both engines are great... You are top notch brother
Thanks Andy! Getting better all the time!
Good content... both B and RB motors are great and the D100 is going to be a nice truck with the B motor in it.... can't wait to see more on the truck...thanks..🔧🔧👍
Can't wait! I’m days away from having the new rockers on and valves lashed
Both are impressive engines. Great numbers! Love the old iron.
You did a great job on both engines and you should be proud. Both are impressive. I'd love to have either one.
Thank you very much!
Both engines are great. I’m a little partial to the 440! Great content Joe.
Thanks buddy! It is a stump
Puller that can move a charger!
That's kinda funny because since my first car (a 72CHARGER) I always dreamed of a warmed up 440 and recently I have gravitated to the 400 because of the potential and I used to think that the 400 was a weak engine with no potential
Great stuff Joe ! I am a hands down 400 old school guy. However my next project will be an A body with a supper snappy 360.
Take care, Phil
Sounds great!
You’re the man Joe💪! That look on Jamie’s face riding in your Barracuda is the best 😂👏👏. For me-I like the 440…I like the way it sounds the best 🎶
Thanks Ryan!
For me, there is nothing like a warmed over 440 on the street. Both engines are great though. You proved that building engines with parts that compliment each other is the ticket to power and dependability. Keep it coming, Joe!
Agree lots of folks think that cheap,fast,reliable is possible but there delusional.
@@apocolypse11 I don't think anything in our hobby is cheap. Nothing. We can save money many times by doing things ourselves but the project still ends up costing more than we imagined. 🤕
Thank you very much!
Wow, great power out of both.
Joe great job. I’ll take the low deck 400 every time.
Lots of potential! I’d love to do them apples to apples
Thanks for posting these tests Joe
Thanks brother
I'm always a old school guy. I will always take the old iron over any modern engine. So it's either the 400 or the 440 over the modern 392 hemi for me. That goes for any mfr.
Nice Joe.
I like the 400 👍🏻
Good little combo
Thanks Buddy
This guy builds 400hp in his house without even trying, next video fast joe makes 1500hp with actual effort.
Old iron in a old Mopar! Both engines very impressive! I would be happy with either. But love cubic inches.
Hey Joe, nice haircut !
Haha! Thanks brother
Hey there Joe, I'm sticking with the old iron 440, but I would go with B1 Heads, but that's just my dream 😊
That’d be awesome!
Cool comparison! Back in the late 70's early 80's I really disliked the 400's was used to the power of 440's and 383's and the 400's were throw away engines! I scrapped 3 that I can remember that were good engines! If we'd only knew what the future held back then!👍
They’re sweet!
Super Interesting !!
Thank you! Cheers!
In a nutshell it looks like you did outstanding. I’m sure a bunch of us would have no problem with you building an engine for us and proud to say who built it. Says a lot about how you represent your abilities!! Ps hope you enjoyed one hell of a Fathers Day!
Thanks Stan! It was a good one ☝🏻
Thanks For the lesson Professor Joe!
Thanks Big Mike!
Two of my favorite engines. But, the 400 to me is superior. The things you can do with it are amazing. Bigger bore, ligther, etc etc.... Drop a 440 crank in it and you have 451 cubic inches. I can go on about the numerous builds but I wont. Also yes, 18 inch collecter extension is a must... I love a stroked 318 also. Many cheap 318s available and boy what fun you can have.
I do love the low deck for in my A body!
Think I like the 406 myself, I have heard that the 400 B block has a stronger bottom end than the 440 RB block so there is room for more power in case you want to make it a stroker and get the displacement bigger and then have an engine capable of more power than the 440RB block can handle and still be a daily driver without fear of block failure in the main bearing area plus have a little more room under the hood, just my opinion of course, anyways I think you may have got Jamie addicted to drag racing and that is not a bad thing, and of course thanks for sharing all the information you have gained, it's really helpful for those of us who don't have time and money for all the R and D good luck at the track Mopar Joe
Thanks Dina! I’ll get to race heads up with this truck in October
I'm telling you right now Joe, both engines would be stellar in my 2005 Dodge Ram 1500. Although, I am fascinated by how much hp and tq you can get out of a 400 block with the right goodies. The 400 block, especially the smog blocks of mid to late 70s are stronger. I wish i had known this when i was a young buck. Guys were pulling those engines out and putting in 440s. Not a bad idea of course but one could keep the original 400 and modify it into a monster. Great comparison son!
Thanks Mike! Definitely more to come on the 400
Awesome comparison Joe! I do like the Gen 3 Hemis but for me it's big block all the way! 🏁
Thanks Tony! Someday I’ll dip back in to the Gen 3 stuff. It’s inevitable if we are alive long enough
Those Sconefield headers look like the real deal ,,, !
It was nice of them to make up a pair for my dyno runs. The operator said, “you’re the only one that’ll probably ever bring a big block Mopar in here.”
Good vid cheers
Thanks 👍
Looks like they are both good solid builds
Thanks brother
Hi Joe! They both came out great.
Thanks Clint! They would move your hotrod along quickly!
@@JustMoparJoe No doubt!
Love the 440’s had a few way back when. But the 406 would probably fit in my old A body a lot easier. Good job on those engines Joe. 👍
got a 400 in my 70 dart. nowhere near as hot a the one in this vid, but it still revs like a 340, but makes awesome tq and hp.
Thanks brother!
Great scientific comparison Joe!
Thanks Buddy!
Great video! Both are damn good builds,if i had those 2 engines sittin in my garage to choose from for my car for what i do with it right now,I would choose the 448....the more torque i can get to get my heavy ass car movin off the line the better lol😂
Torque is king and Mopar is the kingdom!
The 440 is my favorite engine, but the uniqueness of your 400 and its inherent block integrity really impress me, especially in an A body street car. Great job on both. Joe !
Thanks Bob!
Like you mentioned, it breaks down to what its for really. Those 400's have a large and cheap set of stroker kit options where the 440s have about half that and a smidgen more expensive (because everything else is interchange ie heads cams etc). So to me it breaks down to what it goes in... small engine bay = 400 but if you've got the space like a D100 ^cough cough^ then totally rock a 440!
Love the comparison, I knew they had a lot of difference in overall but not THAT much. You know my style, I love my low rpm muscle... I wanted to ask you to run a factory dual-plane on the test to really see how much it shifts all them horsetorque numbers to the low end. Everyone knows the general theory on that but I have a soft spot for complete daily driver oriented builds.
That would have been cool! Maybe next time
I would love to build a 400 but I really like the 440s because of the choices you get on parts there are a lot more options with the RB.
The 440 has shined for many years! But there’s lots of good advantages to the 400 block. It fits really well in to an a body 🫡
You did great with both builds, my friend said 400 was best for the money. Never had either so i can't comment. Great content Joe.
Thanks 👍Jeff!
I know nothing about modern stuff, so I would choose the stock 400 4 barrel I drove when I first got my driver's license. It was in the LeBaron we had at the time. So 406 4 me!!😊
Sounds like a plan!
@@JustMoparJoe I said LeBaron, I meant Chrysler New Yorker.
Both are excellent builds with care taken at each step. Drop either one in a daily driver and go to the strip once in a while. Dependable, performance, driver, racer. Both are winners!
Thanks Brad! They were both fun build and would be awesome in a street rig
Nice job Joe in a A body I would take the 406 all day long because of clearance issues but in my 67 coronet I would like the 448 or in my 86 ram both of your builds are awesome getting closer to my 470 low deck going in my 69 valiant 4 speed too many projects for a 67 old man to keep up with thanks Joe
Right on! Thanks Ray, and good luck 🍀
470 low deck in a 69 Valiant, what brand of tires do you use, might need to buy some stock in that tire company
Info is always good Joe . Old iron is best 😀👍🏻🇦🇺.
I’m pretty partial to the old stuff. Thanks buddy
440 of course,in a B body, room issues in the smaller A body's no so much,
Back in the late early 60/70 I had a 440 in my corrnet 500 , convertible, heavy
and was able with ,line bore 10/10 crank,30 over flat tops, Isky cam, hooker wheel well headers some port work,dual point Mallory ,this combo would put me ,no brain racer in to tye 13 teens, Automatic transmission.
No idea what the rear was, bought the car used, from the dealers personal collection.
The car came with 426 hemi with bad luck ,the story was ,that warranty covered ,two motors.
The dealership serviced highway patrol units up to 100,000 miles then pulled them.
My Cornett 500 received a rebuilt 440.
Yep it was a bad ass ride for me to own at 18.
Thanks for sharing! That’s awesome mopar history!
Just found your channel and I have dreamed of doing your exact build. A 400 in a pickup. I might have to use my Dakota instead. I have a 67 Dart with plans of a 440 “motor home engine”
@@almaylin464 awesome! You’re gonna like my next video 🫡
Personally, I like the 400 block over the 440 block.
Lighter.bigger bore and better webbing
I’m there with you 🫡
What I know is I still want you to build my 74 400 like the 406 for my 1974 Charger.....that's what I know 💯😎
You got it!
If fitment is an issue I will take the 400 low deck. If fitment is no problem the 440 rules the roost. They can keep the Gen 3. I prefer the nostalgia appearance.
Absolutely!
Nice video! All it takes to make a little more then the 440 is stroke the 400 to a 451. Best of both worlds! Either way I love both these engines. I had a 406 in my dart and it just ran great overall. Went 11.42@117 on pump 93. 95% street driven. If it was race only I would of had more cam compression etc in it
I’d love to turn this one up someday!
440 all the way every day. But your 400 is impressive as well and if I was dropping it in an A body the low deck is the way to go. Especially if its lighter than a small block.
Thanks Jonny!
I'm more impressed by the torque output of the 406 with it's 3.375 stroke! The first mild 400 I've ever seen that made well over 500 ft;lbs. I bet it would be nasty with Trick Flow 240's, Track Heat intake, 12:5.1 compression, 7000 rpm solid roller and a T56 Magnum!
I’d love to build that someday and see what happens! I’d always rather do more with less, than less with more!
Lunch Break!!
🥪
Old school all the way Joe
440 any day
I'd rather have a gen 1 392. Not fast by comparison, but way up there on the cool meter. 😊 Anyway great info video. Hard to beat a BB Mopar. I'd like to see what you could do with a 361...well really a 350. But unobtainium.
That’d be cool! See just what happens
Hi Joe, another excellent video. I would like to know if the Trick Flow 270 heads are better than the ported 240 heads? And what needs to be done to improve oil flow in the Block 400 B and 360 LA using roller lifters?
270’s definitely outflow the 240’s. Both come as CNC ported on the inside. I didn’t do any block modifications for the roller lifters. These are considered retro-fit, to be used with the stock block. I will have a 360 with roller lifters soon to show any block modifications needed the LA setup.
I think the 400 with dual quads tunnel ram for me theres just something about cutting a hole in the hood for clearence that works for me
It’s really slick. I know there was more left in that engine as well.
Did you do anything to the Edelbrock e street heads to run the roller cam? This is the best build on a 400 I have seen.
Thanks brother. We just changed springs, retainers, and locks. They’re currently in my 512 with some stout solid roller springs.
I'd like to see the 406 with the TF-240's and more compression - it still overachieved as you ran it though
Thanks brother! ☝🏻
I 'd take the 406 day or night, but no complaints taking the 448 if you forced it on me. Great job building both engines at home Mopar Joe.
Thanks Mark!
Good video. My engine is a RB at 580 cu. What I can say is in a all out race engine the 400 block has a slite edge. The rotating ass. can be built much lighter. with all other parts the same. I was in the 6.1 range with Victor heads. It should be faster if I ever manage to get it back running. It come back from a Pro builder with only 50 pounds oil. I'm old and have a bad back so I'm slow to tear into it. Oh, and header extensions made me a full tenth faster.
Thanks Mike! That’s a big displacement for a stock block for sure
@@JustMoparJoe It's not a stock block. I have a block made by Muscle Motors. Same block as a old world motors block. I've got a 4.530 bore. The block is 70 pounds more Steal than a stock block. It was 840hp on the Dyno. But like I said when I got it back from my builder it only has 50 pounds oil. (not usable there)
@@MikeOCOnnor-jn4ic you’ll get to see the Mega block in my dads barracuda soon. Short block came built from them
A little prejudice but the 406 for me 😎 Because that’s what I’m running
Thanks brother!
Always loved 440's, still have one now - but the 400 is not one I've ever owned, despite it being
considered the best of the B-engines - one just never came into life here.
All things being equal, I'll stick with the 440. Easier to find, easier to find parts for - and easier
for it to generate the grunt we all like on the street.
Great comparison Joe. Thanks for all the efforts.
- Ed on the Ridge
Thanks Ed! I have to agree 👍🏼
I thought the 400 was easy easier to find? Must have been before Mopar Joe let everyone know how good they are!
My gen 3 392 stock bottom end makes 585hp and 580tq. People are getting upwards of 630hp on sbe 392s. Im not a purest be any means. I enjoyed your video!
Thanks brother. I’d love to catch my old 406 up to modern times with some great headflow. I don’t have the headflow to match the gen 3 by any means. I know the right cam will also make them in to new animals! Anything to offset the LS guys!
Can you share the specs on that 392? Cam, compression, intake. I bought a new BGE 392 block, H beam rods, just scored a 392 intake.
@@ragingbull3406 stock compression, stock heads,stock rods, stock pistons, custom grind cam by sdpc. The shop has my cam card, but its very similar to the Texas speed stage 3 na cam. Johnson hydraulic short travel roller lifters, ported intake by mmx, and bbk 90mm throttle body. Stainless Works 2in long tube headers with high flow cats.
I myself would take the 440.
It’s the strong dog
Both were great but that smog motor making 535 hp was a wow.
Love the 400!
Mopars largest factory bore and a strong block for adding a stroker kit or a blower,or why not a stroker kit and a blower just for the why nots of it
The choice kind of depends on what you are aiming for. I think the limit on a stock block 440 is about 650 horsepower realistically and about 6,500 RPM. I know you can do more and I have done it with nitrous. Above those numbers you better have concrete filled block stud girdle and possibly 4 bolt main caps and that's if you wanted to live any length of time. Above 750 horsepower you better just buy an aftermarket block
I’ve recently heard that in many forums. I’m certain I’ll be spraying my 512 to beyond 750 horse this year. Transmission is upgraded finally and rearend should be good to go
Always heard the 400 is the strongest big block Mopar made even though it is a low deck
Sadly, you didn't test the best heads overall, the Trick Flow 240, or 170 heads 😢
The 440 in this video had Trickflow 240’s on it. I think a 170 is a small block ford head.
Good numbers nothing wrong with that you're getting more than 1hp per cube the 400 will have a shorter deck height both are good engine
Thanks Grand!
I have one of those 1969 Charger R/T SE's ? Alas, mine's all stock/original/unrebuilt/unrestored and still in fine original condition factory X9 Black, V88 Stripe Delete..... even the damn exhaust is still factory original so I can't dare touch it's 440 beyond a stock rewinde one day.
Very nice BB's both.... either would put a smile on the face of even the most ardent HotRod fella.
That sounds awesome!
Dream car, would almost be scared to get it scratched, so it probably wouldn't be driven much, except the temptation would be excruciating
@@dinadaughtry8993 I live rural, so I drive it LOTS !
What kind of pistons are you running in that 400? I've been looking for mine but everything I find seems to be bigger than stock.
These are KB hypereutectic. They are .030” over
I have one if each of these in my garage. For a quick street car, say a 66 Satellite, which would you choose to build?
I’d probably go 440 in a b body. Fits right in!
I like em all. But those hemis get nasty with boost!
It’s very true. They have to be the LS fighters of today
If they only made Off the Shelf 400 cubic inch 3.31 stroke forged steel crankshafts, but 3.75 is also nicer crank in a 400
I will have to try it someday!
What about the 383 crank get it balanced with some decent H beam rods and forged pistons, what would be wrong with that?
Like I said earlier, a 451 would be the one to test
I’d love to have one. I know it’s on my bucket list
@@JustMoparJoe mine too. My 74 Duster is getting either a 340 build, which I’ve had the block for 30 years, or a 360-> 408 build. I have access to a 451 but would have to change the 904 to a 727 and change the driveshaft again. Already narrowed a 8 3/4” C body rear for the Duster with super stock rear springs.
There is no replacement for displacement. It's a fact but both do exactly what they were built for but it comes down to dollars spent. As for heads indy is the best I have ever run. Edelbrock are junk in my book and won't sell them or put them on a lawnmower 😂 I like this video it's very informative and gives people a idea on a build path. Price of the builds would have been good too. Bang for the buck.❤
Rooster, I know you’re fairly new to the channel. I have a video comparing the 400 build price to that of a stroker design. Check that out if you get a chance.
Must have forgot about the oil filter stuff
No sir! Keeping it loaded for ya soon
No desire to deal with gen3 ailments... Dropped valve seats, fragged timing chains, flat cam and lifters, etc. Give me an old B/RB any day.
I’ll take Joe’s 512 for the win.
I think it wins😂
Uh, did anyone mention building a 444? 383 block with 400 crank and good heads and intake? Plus it should be lighter than 440 since we’re talking B versus RB block.
Hey Rick! Welcome to the channel. 383’s and 400’s had the same size stroke. The cranks would certainly interchange, with the 383 having the better forged (internally balanced) version of the two. Doing the swap wouldn’t gain any cubic inches. Maybe you’re thinking about cutting down a 440 crank and sticking it in a 383 block. At .030 over, 440 source calls that kit a 438 cubic inch. I’d like to build one for the fun of it someday.
I will take the 440 big block over any of the 392
If you had the trickflows on that 400 i bet you could match that hp number of that 440 quite easily.
I’d love to have tried them. Maybe someday I can go with some 270’s, a big cam, and much higher compression!
And then add the header extensions and it will best it for sure.
What heads you have now on the 406?
Is that a 360 block??? Joe.
its a big block mopar 400.
@Johnny right now I have stealth heads that I did some light port work on
That 406 is begging for a turbo.... If and when that time happens!
That would be awesome! I may need to upgrade that cast crank for that 😁
@@JustMoparJoe think those cast cranks are a little stronger than we might give em credit for, same with the 400 block itself! Anyway, keep pumpin out the videos, keeps me and I'm sure alot others motivated
@@frankycriner9890 mine loved the 150 shot at the track about 10 times in a row!
240 tf would make thiat 400 wakeup! Torque will never beat the 440
I definitely think it would take some more revs and cam to beat the 440, but the 240’s seem to be the better choice. Is it worth an extra $1,000?
Your not using the best heads👎
I’m showing you what was purchased and used. You’ll need to go watch Hemi channels like Michael Yielding to see the best heads used.
