That insta power initially is what made 383 roadrunners king of stop light racing
I would challenge you in a Pontiac or a Buick
@@64fairlane305 You would be looking at some Mopar tail lights.
Rich kid
@@rodan2852 Ihad road runners I was there they were not impressive.
This motorhome 440 needs a turbocharger.
For reals
As I would agree. But on my 72 there aint really room for 1 but a supercharger fits.
It really needs a massive supercharger and tuneable efi with that compression ratio,those heads and cam..
The stock Mopar with that mild cam was actually pretty impressive . Would be perfect for a low and slow cruiser , that much torque right at the start of the pull it would light up some tires good off a stop light 👍
I would love to see you guys do the difference between a 426 hemi and a 426 wedge. Actually been pretty curious about power between the two
I just watched Nick's Garage make 401hp from a Mopar 383 pickup truck engine.
With that compression it’s screaming for a big ol turbo
Or a huge blower...
Right could push quite a bit of boost at that thing with that low of compression!
"And it's 7.4:1 compression and there's nothing you can do with that "
*18lbs of boost giggling*
I love how Dulcich and Freiburger geek out over the Mopar 383 during the dyno pull. It's so genuine and real.
Love 383s.... All my Chargers were 383 cars and they never dissappointed me!!
@@wheels-n-tires1846 Ok, you changed my mind. The 383 hunt begins!!
@@improvisewitme they really are great engines!! And while the 383 is great, dont discount the 400...theyre plentiful and easier to find. Ignore the bad rep they got from being 70s smog motors!! They respond to the internal mods amd bolt-ons the same way, plus the few extra cubes can't hurt!!! Also, if youre building an A-body, they fit much nicer!! Ive got a 400 and trans stashed away now for a future project!!
i raced 383's and 440's both,i quit racing the 440 longer stroke engine in favor of the rod stroke ratio 383,i buzzed my 383's to 7200 often using isky cams and quality parts,now that i'm old i've got a dead stock 383 magnum in my 1969 d100 with a np435 truck trans,and 3.23 suregrip,only change to the mag is the carb,i'm like freiburger i like the tq carb for gas mileage,i'm getting around 17-19 at 1800 rpm and all the power i could ever want,bigger tires were necessary,383's 3 million made, parts galore
@@wheels-n-tires1846 Don't forget, the 400 is the strongest BB Chrysler ever made. Extra webbing, I believe in the crankshaft area.
this drives me crazy and never gets answered. Is it Dole-check or Dull-sitch. David has been using both in the same sentence for decades.
His actual last name is Dulcich, and is pronounced the latter.
Dulcich...a good Croatian boy.
He calls him dulcheck because his old mentor could not pronounce it correctly, and that is just what he called him.
@@large_n_widetm2116 that makes sense. I do the same to a co-worker (calling him by someone else’s wrong version of his name)
@@lukepokrajac1057 don't tell the Serbs....
How about getting an old 400 Mopar and putting in a 440 crank? I’d love to see that.
The 440 just had too little compression to do anything. But super charging would help off-set that issue!!
Right?? That CR just screams "blower motor"!!!
Yeah, but those stock cast pistons wouldn’t be able to handle much… which being youd want to tear it down and gap the rings for boost and all anyway (I would at a minimum throw in bearings, rings, new oil pump, and clean and check everything out in an engine that’s going to be beat on, boosted, sprayed, etc.. and with any pistons, stock, aftermarket, or otherwise, you’ll want to gap the rings for boost) then you may as well spend a couple hundred bucks and get a set of the forged speed pro (trw) stock replacement pistons, which are the same weight as the stock pistons, so you don’t have to worry about the balance or anything like that, and then with the forged pistons, forged rods (which all mopars have forged rods from the factory unlike the other brands) you’ll be able to live with a bit more boost..
The only thing nowadays with the stock 440 crank in a 400 block is that by time you spend the money in the machine work you can get an aftermarket stroker crank.. and then also with using the stock crank, and then buying your pistons, rods, bearings, rings, and the balance job you are looking at the rotating assembly costing more than a stroker kit that’s already balanced (which I would still have the balance and all checked to make sure that it’s good to go)
@@chriswest5360 true... Of course youre right about the rimg gaps and some fresh bearings etc. Sometimes low buck is the only way though... Eons ago I built a 440 for my 68 Dart, but no way could i afford new pistons. So after work I milled .065 off the 452s I had laying around. Did spend $13 for the MP porting template, and lotsa hours, but ended up with compression and decent flow for basically nothing. The Dart became my daily for years, and eventually broke into the 11.50s. Of course, being a fleet mechanic for a wood mill with a decent machine shop comes in handy...!!!
I’d sell my spleen to get you guys to work on my 440.
It needs help…bad. 😩
Keep your spleen!!! Those things can be built pretty easy n cheap!!! Last 440 I had took my 68 Dart into the mid-11s with stock bottom end, milled and MP template ported 452s, cam, intake and headers. Had about $3k into the whole car... Ok it was 10yrs ago but still...!!!
Built by Steve a 2 in the morning, still beats anything I could achieve.
Sign the RPM ACT petition EVERYONE!.
This needs a pin
Why? It is not going to do what you think it will.
@@SophiaAphrodite You are the first to poo poo the move in this direction. Why Bogard?
Signing a petition isn’t activism.
Hot Rod Flash Mob on Washington D.C. on a Friday afternoon would get some attention. Signatures won’t amount to much.
That's what I had in my 77 W200 crew cab. Same cam and I absolutely loved it and it rattled windows everywhere I went!
8:55 383 Mopar hit a wall at 5400- drop-off was not smooth. Valve float, ignition, rev limiter, or intentionally handicapped, because it just couldn't win, could it?!
I still regret selling my air grabber 1971 GTX 30 years ago........ $1,500 bucks 🤧
😣
I feel ya
You did very good. The stock 440hp musclecar motor was rated at 375 gross hp. The 440 Six Pack was rated at 390 gross hp
The Chrysler would have won if you reversed the pistons.
lol i’ve seen this multiple times from tony and david said it doesn’t work but it was in multiple books from chrysler hotrodding. it doesn’t show up on a dyno but there is a performance gain although small it works if you already have the motor apart
😂😂😂
Left to right or just turn around
@@randee7772 left to right is the easiest. Otherwise remove the piston off the rods and turn around. Stock GM rods have a small oil squirt hole between the rod and the cap. The squirt holes must point upwards towards the camshaft for lobe lubrication.
@@randee7772 Left to right is the easiest way.
"I chose this thing because of the SPECS!"
It would have been interesting to walk that engine up in Compression Ratio and dyno it for each increase
A "Compression" dyno session was done on a 440 and it was found that every point of compression was roughly 15-20hp. Three more points of compression on the 440 could have increased it's output by 45-60hp.
You guys need to build a Mopar for NHRA Stock. Must retain original cam lift, CR, intake/carb, valve size, head casting, stroke, rod length, for HP claimed, and maximum .070 over bore. A lot of Mopar combinations will run one second, or more under their indexes. A good 1970 340 Duster/Demon fits in E/SA and will run 10.60's! Cool video.
The horse power is in the block it needs to be 0 decked, line bored to get the bores centered and straight then, you get a light weight rotating assembly and main girdle if you want 650 horsepower in a dependable street car, or no girdle if you don't go over 550 horsepower anyway getting the block decked and line bored to center up the pistons and bring them to the top of the deck will pay off big time
A competitive NHRA engine is a very serious and expensive endeavor regardless of being classified as "stock".
When I saw the thermoquad I got real excited.
And then... on went the double pumper.
❤❤❤❤❤
notice the compression starts at 7.5 to 1 and gradually goes down as the video plays!
I think the 7.5 was either a guess or maybe factory stated which were never real accurate. As they went on they actually measure to determine what it was. The replacement head gaskets were also thicker. I didn't go back and actually watch it again but I think I'm close to what went on.
Well you used to 350 Chevy but the 400 crank for a 383 stroker won't you actually use the real equivalent of the same small block of a 318 making a 392 stroker isn't that more matched up with the same 10 cubic inch more than a 383 big block board over a few thousands isn't that more equal oh that's right or is it the same old story Chevrolet don't like getting beat by Mopar
I LOVE ENGINE MASTERS!!!! I LEARN SO MUCH!!!
❤❤❤❤❤
Awsome show, thanks guys.👍
Mopar/cheap...do not belong in the same sentence...you need to refinance your house to buy anything for especially the older ones
@Art Brookey I'm always flat broke or on a super tight budget and a 68 Satellite Roadrunner clone has been my daily driver for over a decade. I have about $2K and about 400 HP in my current 360 and the car weighs about 1000 pounds less than a new Charger or Challenger and completely blows them away at stoplights. You can build a good Mopar on a budget but it takes a lot more thought than a GM.
and you need to throw the catalog at a Chevy or Ford to match a MOPAR, so which is *actually* cheaper?
@@Impactjunky Where? I live in the Midwest and people want $5000 for a Volare wagon.
@@rocketsurgeon11 Not true. the similar 302 I am building for my Ranger would crush the 318 I had for my Satellite. The bolt on horsepower is insanely cheap compared to a Mopar.
@@SophiaAphrodite and how many parts are you BUYING for that 302? Oh. The *factory* 318 will SPANK a similar year 302. Mod for mod, the 318 straight KILLS a 302.
That's a lot better stock than I would have thought
That's because they were doing a "Gross HP" dyno run. If you add all the front end accessories like Power Steering pump, Air Conditioning compressor, Water Pump, Fan, and the Alternator, the horsepower would have been much closer to what the engine was rated at originally. Mid to high 200hp range.
@@topenddeanthe 383 came with standard 330hp
ThermoQuad !! 😁😁👍👍
This was my favorite carburetor back in the 1980s for my 1972 Duster 340 and also my 1969 Roadrunner 383... I understand carburetors and like working on them so I could make this perform as good or better than anything else.
Mine too!!!! Love the tunability and potential of a classic early TQ!!!!👍👍
I did same. Love thermoquads! Had a few of them. Took the best from each made one great one. Rebuild kit from Nabco. Larger jets. Learned to set up flawless. Ran like a top on my street/strip 440! Had 750 Holley, wouldn't run right would get hot. Thermoquad wasted the Holley. I let that carb go with that engine when I sold it. Big mistake! Now Holley makes a thermoquad reissue. Cool
Worst cam series ever! Anything but thumper...
Chevy has 10 less cubes, smaller valves, shorter intake runners. Not too shabby.
I guess that's why it took 200 more RPM and slightly more time to make the same amount of power.
There you go Steve, good job on the cam segment, we want to hear more Mr. D. Thanks guys peace.
But when it comes to reputation. The Mopar motor wins alot more on the tracks as Chevy though. Especially with drag racing.
You've no clue about dirt track racing. I spent decades watching almost every car being a Chevy.
Woah it's almost like a big block will out perform a small block haha
I am glad y’all have done motor home 440 test with different heads I want to see Indy or b1 heads on 440 bored 30 over to 446
My dads favorite engine was the 383 Magnum. He was beating 440's and even Chevy 454's on the street because of it's low end torque.
Exactly!
Having driven both, my first reaction to the 383 was "Where's the torque?"
Your statement has zero mathematics behind it. There's alot of people out there that have built total junk and tried to race it. Doesn't say anything about the quality of the engine in good hands.
Luv your guys vids,so informative and excellently explained and video editing,cheers,best wishes to all,from,Auckland,New Zealand.
850 dp on a kero burning 360? Yeah right!
383 is NOT a small block. And as was pointed out has a LOT more advantage. So even with the same capacity hardly fair!
The Chevy 383 is as it is a stroked 350.
@@SophiaAphrodite Bored and stroked.
we need engine masters episodes on youtube
I’m wondering why he didn’t mill the heads for a little more compression?
Haha... That's what I did when i couldnt afford new pistons...took .065 off the 452s and it woke right up LOL!!!🤣
They did...to make it fair they matched the Chevy.
A set of heads would be great on the motorhome engine
Can someone tell how to find out this exact build spec on the 383 Mopar
I hope you all are recording Steve. That knowledge is paramount for our sport survival.
I’m surprised the Mopar outpower the Chevy and the reason I’m surprised is because the Chevy engine has a lighter rotating assembly.
Too bad the motor home didn’t have its stock heads for a base line.I thought original compression 8.2 ish 77/78 ish.I thought it was only the HP (police)that only had 7.6ish
Love these guys ,very entertaining
Probably the best jobs ever
Motor trend You Tube got you famous. Real Talk. I Enjoy Thank you
famous is relative, I knew of these guys back in the 90s when they were writers/editor(s) for various car magazines
can't believe people don't seem to know that freiburger was editor of Hot Rod Magazine and other magazines, and before that he was a writer at those magazines... for many years before Roadkill or RUclips or people having Internet access at home was even a thing. he's been in the automotive media industry since he got out of college... I don't know as much about steve but I know he's been at it for quite a long time as well.
not that it matters,I just think it's funny when people think these guys popped out of nowhere and became sucessful all because of RUclips.
Freiburger has been doing this for well over 20 years. He's not new to the game. Dulcich has been around almost the same amount of time.
I had a motorhome with the 440 in it. It was a gas hog and a dog. My brother's 454 motorhome made 100 more HP with the same torque, and got better mileage.
The Mopar my lord she was singing
I LOVE IT!!!! I LOVE LEARNING ABOUT MOPAR MOTORS!!!! GREAT VIDEO AND A GREAT BUILD. THANKS FOR SHARING!!!!
I can see that being a scream for a hot rod for cruising and just enjoying the ride
God I love a mopar and a street cruiser with a little punch engine.
First the engine is a motor home 440 then at the end they said it was a 383 Mopar… wth 🙏🏻
They tested 2 motors; a 440 from a motorhome and a 383 Magnum. You must've skipped through the video.
Just throw a 426 Hemi in it and call it did.. What's 25k amongst friends...

When are you going to do a old school 383 chevy stroker VS. Chevy 6.0L LS and both engines had roller camshaft roller lifters roller rocker arms
The stock 1968-69 440 magnum was rated at 375 HP
compression......cam 0degrees advance.........hipo heads........fix this
or your. going NO. WHERE on 440
Great job... But why did you take a 383 chevy stroker motor ... !! chevy never made a 383 motor.. and run it again a true mopar 383 motor..
Anyone else getting Harrison Ford vibes from this guy?
7.2 compression ?? the low performance motorhome 440's were around 9.0 so somethings wrong here .
I had a b Mopar and a small block Chevy apart at the same time I swear them Mopar heads sure look a lot like the small block Chevy
Or is it the other way around? 🤔
@@thespicemelange.1 they sort of look similar and some of their Construction it's one way or the other lol other than rocker bar and rocker arm water in the intake the ports look the same they have the same spark plug
Chevy copied mopar

440 longer connecting rods ? .125 longer or maybe .145 longer based on cost.
Woah. A youtube vid from them.
Freiburger and Dulcich we need dyno test of the 426 hemi vs 454 big block chevy
I think we already know who would win that battle
There's a reason NASCAR banned 426 Hemis. Usually because they were walking right past 454's.
Funny everyone wants to see 426 hemi’s no one runs them on the street, must me a reason for that! I had a Super Bee with a 383 back in the early 80’s. Went looking for a hemi, even mopar guys were telling me you would be better of with a 440, 383, you name it. They would say really you don’t want a hemi. Found out how expensive mopar parts were. Sold my Super Bee and got a 68 Camaro. Wanted a 10 second street car and knew I would never get there on my budget in a mopar.
@@moparty3875 true story, i beat them regularly, have a nice day Slopar!
@@TwentytenS4B8 NASCAR never banned 426 Hemi's. They required any engine being run to actually be a production engine. Mopar stopped making the 426 at the end of the 71 model year so they started using the 440. Now any engine over 305 c.i. was banned for use in the aerocars like the Superbird, Daytona and Talledaga Fords. That is why they dropped them in 1971. But the Hemi was never specifically banned in NASCAR.
Guys, when Dulcich made the cam install to 101 degrees to close the intake valve sooner, was he taking into consideration the fact that the cam that was chosen would not produce power unless the 440 you are running was at 9.5:1, the lowest the cam could run and still make power? Get that out...just wondering.
That's only one degree advanced from spec. The specs on that cam are very similar to the Hughes Whiplash cams that are designed especially for low compression engines. In fact, they don't recommend over 8.9:1 on pump gas! There must be something with that tight lobe separation angle and long duration, but the science completely eludes me.
So when it went from a 4:40 mobile home motor to a 383 HP motor you guys don't make any sense
Nice.. change multiple things at once so you don't know what part effected what. Great methodology.
I say skip the middle man and take that dead weight straight to the salvage yard.
Old school is still cool.
I made $$ as a teenager doing tune ups and I rebuilt hundreds of carbs in the heat of west Phoenix. Thermal Quads warped and cracked, if over tightened lots of carburetor main bodies would warp, Quadrajets and Carter AFBs included. As time passed lots of base plates that required separators got lost and heat risers rusted shut so intakes filled with carbon that was hard as steel. A big block with a properly jetted Thermal Quad made tons of torque and buckets of horse power. Holly's just dried up and crapped the bed in the heat, more than one car caught fire thanks to Holly double pumpers.
What about a longer connecting rod on the Mopar to increase compression
@@brandonrobishaw7606
I saw a comment recently suggesting an offset wrist pin bushing to place the piston higher in the bore. If suitable length connecting rods were available, or offset bushings possible, why aren't they being used?
I did not know you had Robert Duvall look alike working for you
Did you put the pistons upsidedown, backwards and inside out to get an extra .0045 horsepower?
@mopar one It's funny because at least one old Mopar performance tech book told you to turn the pistons around backwards.
@@Impactjunky yup
ANY ADVANCE ON THE CAM CUTS HORSES.....YOU GET
TORQUE.......
He starts the video calling it a 440 then says it's a 383?
Now give the Mopar the timing it wants. Eat that chevy!
Mopar 383= 3.38 stroke.
