CHECK OUT THIS VIDEO WHERE I COMPARED THE STOCK EXHUAST MANIFOLDS TO 1 7/8-INCH, LONG-TUBE HEADERS ON A 360 DODGE MAGNUM. I ALSO TESTED THE EFFECT OF ADDING NX NITROUS TO THE JUNKYARD 360 MOTOR. HOW MUCH POWER WERE THE HEADERS WORTH ON THE STOCK MOTOR? HOW MICH NITROUS DID I ADD? CHECK OUT THE FULL TEST RESULTS.
Pretty impressive torque numbers for a beaten up junkyard engine. Magnums love bigger cams, go for it!
The only thing that could make this better, would be to get the next size up cam with the modded kegger. Reason why would be that's what most of us have.
The pull with the headers sound SO much better then the wind noise the stock manifolds made. I have a 95 5.9 and a 90 spirit with the 2.5T1 but that is slightly modified so these episodes are helping me all at once. Thank you for everything richard you give your viewer's so much influence and it's greatly appreciated🇺🇲
I agree 100%
He is like a ghost, I never even knew he had responded, but not surprised in the least bit, this podcast has more viewer interaction then anything else I have seen👊🏻🇺🇲
Loving this Magnum series Richard!
Those had to be the worst looking exhaust manifolds I've seen since I pulled a 392 Hemi out of an old Imperial. They were big in the front getting smaller towards the flange. With that said they actually didn't work that bad. I figured there would be at least a 20hp gain with the headers. Can't wait for part 3!
I really enjoy The Other Guy serious. I love the LS and turbos, but you can only do so many things to them. It's good to see something different.
Definitely what I figured. This is the dyno graph I pictured from my dakota RT. Love to see heads cam. That stock cam is a dud for any real power
It is ridiculously small and you can't make any real power without changing it. Mine noses over so hard at 5,000rpm it feels like I am dragging an anchor.
Finally someone to give us a more detailed overview of the 5.9 magnum.
I'd love to see you run VRPs in a kegger on here (utawesome performance sells them, and they also sell a 108mm monoblade throttle body for the magnum).
Watching closely as I have one to build right now! Looks like the long tubes are the first step. Thanks Richard!
Awesome to see some magnum love. Please keep the engine injected. That’s the main reason mostof us swap this motor in. With the injection system they are smooth running and super reliable. I would love to see cam, intake, heads etc. upgraded while keeping it injected. Thanks fir the great content.
I click “like” before I even start watching Richard’s videos now.
'what we like to hear
I had an 84 Ramcharger that came with a 360 LA engine with an A727 and a NP208 transfer case and it always ran great (even with the Thermoquad), but if I drove it for more than 30 minutes it would vapor lock and just die until I would pour some gas into the carb. I got sick and tired of screwing around with it so I swapped in a 360 Magnum with the same A727 and NP305. I integrated the stock wiring harness with the Magnum harness and ran it off of the stock ECU and it ran great, sounded great, and made good power surprisingly. The LA only had 64k miles on it, so I sold it to a buddy who built it for his old D100.
The 1992-1993 Magnum cast-iron exhaust manifolds have a larger collector flange diameter and combined with the 2¼" Y-pipe into 3" exhaust is a tough setup to beat. My Engine Quest Iron Lightning heads love it and it looks stock.
2.25” Y pipe to 3” exhaust seems totally pointless lol. That Y pipe I can almost guarantee is choking a 360 CID V8 unless it literally has no cam and junk heads.
Just realized you also said “cast iron manifolds”. So yes, you are indeed down on exhaust flow anyway well before you get to the 2.25” Y anyway so the Y pipe isn’t actually an issue right now; first problem is the manifolds. If you were to go to a long tube header then the y pipe would be your restriction at that point. Depending on your cam profile/compression and specs of your EQ heads, I’d venture to bet you’d pick up no less than 30 HP right now by throwing on a set of longtubes and going to either a full 3” Y pipe/exhaust or better yet 2.5”-3” dual system from the headers back. If it’s a high compression motor with a lot of cam, more like 50 HP from those aforementioned exhaust improvements. Just saying 😀
Here's the part that you failed to recognize here. The 1994-2001 magnum manifolds have smaller port's and a 1⅞" discharge with 2" Y-pipe into a 2¼" exhaust. Testing over the past 20 years in my 1993 D 250 5.2l automatic vs my 1996 1500 5.2l automatic shows a big increase in flow with the 1993 manifolds and corisponding Y-pipe with the chassis dyno showing 387hp at the rear wheels and still getting 20.94 mpg on the highway. When people are running their mouth about factory exhaust manifolds they are talking about the 1994-2001 units because they don't even know that the 1992-1993 exhaust manifolds are different. They are mistaken because they think that they are all the same and they are not.
50 hp?
My 92 Dak has 2 1/2 outlets and I swapped yrs ago to a set of Hooker Pacesetters and saw about 1 tenth difference at the track. FlowPorting like the F.A.S.T. Class cars might be something to try, for that factory look.😉
I wanna see a modded barrel intake manifold on the dyno
Why, they are garbage. They have zero redeeming qualities. If you're a mopar guy it is litterally the biggest problem with the magnum motor
Go watch Thomas Beyer on you tube. He did his own port work an what not an picked up 15hp an 20 lbft. Very worth it
I love the content! And with three small block Mopar builds in the near future the info is invaluable! But damn, the stock music clip over the work montage is ear-splitting with that out-of-time *ding ding ding* over and over.
Richard is the man and the best engine dynamometer scientists on UA-cam and nick being the best as well
This is the test I've been waiting for as I'm readying a stock 5.9 for my Dart Sport. Starting with a carb setup on a Edelbrock 7577 dual plane air gap. 288hp is 40 more than the stock number. And torque is impressive too! This also shows what a good tune will do for a Magnum or any motor for that matter. Thank you for doing this Richard!!!
My friend had a 2003 Dakota R/T that we ran nitrous on...sometimes a 250hp shot lol....it was a beast from 0-80mph
It kept burning up the cats and the dealership said "this is the last time we are replacing the cats...stop running nitrous or we are voiding the warranty"...lmao he sold it with 82k miles on it and it never had any mechanical issues other that the cats...very reliable truck.
@@jorge-eh7qp I'm surprised they didn't take the warranty away the first time 😂
They sure are a brick over 100! I ran mine at the track when I first got it. It felt like a 13 second truck in 1st gear, a 14 second truck in 2nd gear, and a 15 second truck or slower once it hit third. 15 flat at 89mph. :(
@@CarsandCats They Really were A DISAPPOINTMENT.😞My 92 Short wheelbase 318 Dak.Was Faster, with just a Homemade Coldair, Pacesetter Headers, 4deg.advance,&3.55s,With Drag Radials. I got 14.67@92 mph in Cool Air(65°?) At ALABAMA Intl.Dragway Yrs ago.😉
@@CarsandCats my stock 93 ram feels a hell of alot faster than that.
Nice to see Mopar Love.
Enjoying this series. Thanks.
An m1 or rpm intake should wake it up a lot compared to the kegger. Cams always help. Mopar heads have always been restrictive, if they weren’t they wouldn’t have had come out with the (W style) race heads.
Love it
When people say you cant do much with them modern 360s then you just rev up yours and tune their big mouths out.
Love the Magnum videos. You will pick up a ton with a camshaft. As I'm sure you're aware, the stock Magnum cam is teeny tiny. I think it's well under 200* duration at .050. I've sprayed 250 through Nitrous Outlet Stinger on my stock 5.9 many times, with a carb, good fuel, proper timing, good plugs, etc. It's no LS, but for something you can pull out of the junkyard and toss in, it's fantastic HP/$$, especially in Mopar world.
stock 5.9 cam is like 192 @.050, .400 lift, 113 lsa. 5.2 cam is actually bigger. its like 194 duration, .432 lift, 113 lsa.
@@frigglebiscuit7484 Yeah, tiny. Given the flow of the Magnum heads, it seems silly that they were so conservative on lift.
I put a small Lunati 20200715 hydraulic roller camshaft in. 213/219, 112, .485/.485 in and it was worth a ton on the chassis dyno and took the rpm range up to 5500-ish. Makes just shy of 300 rwhp with headers, 4bbl, 904, etc. You could go bigger but with a tight nitrous converter and tons of street miles it works and sounds great. It's certainly no LS, but it gets down on 250, especially considering it's a $450 mopar engine, and it's only had the valve covers and intake off since it came out of the yard. Of course, I did kill one figuring out the n20, and it goes through a timing chain every year and a half or so....
Do a cam swap
Magnum motors are notorious for small cams
This👆🏻👆🏻👆🏻👆🏻, it’s begging for a cam!
Likely a peanut cam like the Chev TBI engines of that time.
@@rotaxtwin 192 duration, .400 lift. yup, its a broomstick.
Yes richard thanks i have a 360 magnum making it to a 408 soon
I’m still waiting on a two barrel on a kegger intake I’m excited to see how it works
Also Loving the Magnum videos
Perfect timing since I just bought a 74 mini Winnie with a 360 I’m going to be modifying soon
I have so much stuff laying around for that engine. Great platform for sure. Early ones pre 96 had more compression and a better camshaft.
Usually you spray Junkyard engines just to make sure the rings are seating
it helps re seat them
😁👍👍
Great to see the magnum results. Thank you. If you have time it would be interesting to see if the old "keg mods" really did anything.
I just got done with part 1! Good timing!
Great test Richard! That thing is gonna love the GT45!!!
I would like to see a comparison with mid length headers vs stock vs long tube. Lots of cars cant get long tubes to fit so it would be helpful to see if the mid length are worth the cost.
Building a 360 for a 2000 ram 4x4 and by necessity had to buy EQ heads due to multiple cores being cracked at exhaust seat. Looking forward to future tests! Thanks Richard!
Awesome, looking forward on test results with a 4bbl and a GT45
THE VERMONSTER thanks you I'm a huge Mopar fan also this gives me a blue print to copy so I can build a 360 your awesome Pal
300hp on the money! Hey, Dulcich and Frieburger could smack those primary tubes, with hammers, a bit and probably pull a few more HP out of it! LOL.
Turn the pistons around!
Eh, you can get more power from stickers. Lol
NO! Just NO!🤔
I hope you do the "Kegger Mod" before you swap intakes . Ive done that mod on my 5.9 and it feels like something that works....
Glad you mentioned this
I just replaced the belly pan and didn't mod it because I plan on swapping intakes later. How did it work out for you?
Agreed. When i replaced the belly pan I did the mod as well. Now I have an idea what a set of flowing exhaust and headers may add, perhaps even more with the kegger mod.
So what would you classify tri-y headers as, shorty or long tube? Something else? Mopar Performance headers for magnum engines were tri-y’s with exit flange at or below oil pan gasket height.
long tubes
Would love to see a turbo setup with the kegger intake
Hell yeah, I second that! Also would like to see a VRP kegger too.
Blown plenum gaskets galore 😂
I wish the 360magnum had a more modern efi intake manifold selection , since the m1 is out of production and is priced like holley hi ram, really dying to hook up my holley terminator x to my 360 magnum in a d250 but intake manifold selection kinda leaves me on the fence. Awesome tests Richard!
Hi
@@junkyardboost8372 whats up dude
Magnum exhaust manifolds are a good upgrade over 360 LA manifolds
92-93 Dakota V8 manifolds flow more than later versions, long tubes are Great but Expensive. I'm looking forward to this and the RichOmnini.👍👍
Strong torque from a stocker. Can't wait to see how the top end tests do.
Very cool. When are you planning on flipping the pistons backwards?
Man I don't know how I missed this one, very cool video thank you for doing it. I have a 360 magnum that is carburated I am trying to budget race. I just bought my first nitrous kit, looking to spray 150 shot through it. Wish me luck LOL
I love this. Stuff every LA guy should know, grab a free junk magnum and run circles around almost any older small block and it’s almost 100% bolt in. Cam swap is huge, but can also give a guy a mechanical fuel pump eccentric if he’s insistent.
I’ve always done a Chinese dual plane/carb swap but now that’s changing with so many tune possibilities that didn’t previously exist.
Remember when a stock magnum had to get a cold air, exhaust, cam, headers and a mopar computer for a 50hp gain!!!??? Crazy
Keep this series going
Please build this engine up naturally aspirated please!!!! Do a cam and heads possibly? Definitely at least a cam and intake
It would be really nice to see someone dig into the valve lift losses you see on Magnums because of the goofy pushrod vs. lifter angle, and the myth vs. reality on the Magnum lift limits due to the valve guide bosses.
Good suggestion!! I'm curious too! I may be wrong, but I think that goofy lifter angle was a remnant design of the Poly engine block.
Could you please not put a carb set up on there? I'm not hating, I just want you to push the stock set up with cam, springs, and boost. Mostly because of your gonna buy this engine, it already comes with this stuff. Not a spendy intake, carb, and then ignition management too. Thanks
So what sort of power can you put through a stock Mopar engine? The magnum will have a cast crank, 2 bolt mains, pretty basic rods and cast pistons. Stick a pair of turbo's on this with some extra ring gap and see what happens.
Always love the other guys stuff!
Interesting gains for not that much money. I'm enjoying this series, even if I prefer the LS.
Why not stick with the factory style efi try the mopar M1 intake or Hughes Airgap which is what I run on my 98 ram 1500 curious of what its running vs stock kegger
I'd like to see all bolt on roller rockers and modified barrel intake on a 5.9 Magnum
Bring on part 5… the piston swap! J/k dude this is a great test project. Any chance you can find a tunnel ram for this test? Did they even make a tunnel ram for the magnums?
I would like to see the dyno results from the kegger mod with vrp plates and throttle body mod (shave the top and port the top of the bores). Last year i did the kegger mod with the vrp plates. I am really happy with the results! Dropped the 0 to 60 time by a full second. I posted a video showing what was done, including before and after 0 to 60 runs. I haven't done the throttle body mod yet. Plan to do this soon.
Would like to see what the cheap eBay headers do. I think they hurt power but I'd like to see how much. I'm taking mine off and modifying some long tubes to fit in my Dakota RT then back to the Dyno.
What abought duel plan,after maket efi(holly,fitech,etc,)turbo?
You gotta do cams man these engines got tiny cams dude
Live it......real world results as always Richard .....UDAMAN lol
Richard - Will you do a XE250 and XE268 cam equivalent roller like the XR258HR-12 and XR268HR-10 cam like you did in your LA build (Dodge Trades Man) so we can see a direct comparison between the LA and Magnum motors cam for cam? Thanks Bruce from NZ
Possibly!
I love that fogger system!
Check out utasome performance. Marty is doing some really cool stuff with the 360, mostly torque focused using reworked stock intakes and single pattern tight lsa cams. Some impressive torque numbers and decent power.
I used the plenum plates, and It definitely worked. No silicone, just overnight cured jb weld.
Great to see a Mopar motor a lot of people still use daily. Unlike a carbed 340/360/440. It would be great to see a modded kegger. Or at least remain fuel injected with stock electronics and fuel system. I know peak numbers make better videos. But who's going to pull their kegger intake and replace with a carb on their daily Ram?
Pull it and have the Runners Milled and add the Aluminum Plate.HUGHES ENGINE STUFF.👍👍
I can't wait to see how much boost that keg can take before it splits!
Nice. But i have ran the NX 41 jet on my 3.9 Magnum V6. Currently running the NX 35 jet in it. It has (so far) been taking it like a pornstar.
🤣😆🤣😆🤣😆🤣😆🤣
i have an 02 dodge ram 1500 with the 360 and I'm not sure if long tube headers are available for my application. this series will help me allot with this build.
The only ones i know of are pacesetter and they do not fit well in a 4x4
@@mikekeeler2566 my truck is 2wd. Pacesetters are thin and have terrible coating. have you heard of them rusting through or failing? i would consider being them up if i went with them.
@@PANTYEATR1 i had a set few years back, they real decent quality with welds and tubing was 16ga like almost any header out there. And the flanges where decent thickness aswell. The thing i didn't like was price, and yes the coating is just for shipping but they did offer ceramic coated ones. And they want you to use the off road y pipe they make. My problem tho was clearence with the drivers side collector interfering with the yoke on the front driveshaft right where the primaries where welded to the collector. I tried to clearance it in that spot but no go. Seems i got one that was crooked or something
@@mikekeeler2566 your truck is a 4wd correct? i currently have shorty stainless steel headers and i made a mandrel bent 2.5" Y-pipe that goes into a 3" cat-back. i may have to check pacesetter out. it's been a while since i used their products...
@@PANTYEATR1 yeah it was, i removed the front drive shaft to run them... kinda made the truck useless that way. lol no longer have the truck, but when i did have the pacesetters, i had true duals 2.5" to some thrush chambered mufflers to rear axle dump.
I would like to see the difference between the early magnum exhaust manifolds with the larger outlets vs the later ones vs short headers vs long headers.
4 hole injectors are a good upgrade😊
I'd love to see a header comparison Richard 😏
Summit headers are cheap 😁
Hint, hint, nudge, nudge....
Personally I blame squirrels
Realy exited about this series! I have the 2002 5.9L and i know we get tiny cams stock
Do you have any issues with fresh air contamination having the O2 sensor so close to the exhaust outlet?
at low speeds -yes
just for s&g, 1/4" stroker crank, +.030, 10-10.5 flat tops, ported heads and a six pack for induction...u pick decent cam....i wanna see what it does na
Mopar guys go big with the crank. Sbm has a 9.6(?) " deck and stock 6.123 rods. Stock 360 has a 3.58 crank and 4" crank drops in usually with no grinding with stock rods. They also have a cam high in the block keeping it away from the rods.
by chance i came across a man that had Xheads at the Mopar Nationals in Columbus Ohio. these heads never been worked on. friend has a machine shop, and he ports them for me. long story short. i only got 383hp but the torque was 460. i have the 360 in a 79 step-side. i love that lil engine. its like the timex and energizer bunny all rolled into one. id like to get a set of aluminum heads
Those heads will support a decent amount of horsepower, if you're a little generous with the cam kit and don't hold back on the carburetion.
MAGNUM 360!!!
Any idea how much gain I’d see without the the Holley engine management?
the nitrous adds to whatever is there-the gains would be the same
Huges F1 air gap puts up great numbers for a kegger replacement.
Richard - What is your full advance at, I thought I heard you say 22 degrees in the last video? Thanks Bruce from NZ
total timing was 27 degrees (na)-we retarded it 4 degrees for nitrous
@@richardholdener1727 I am running the EQ heads, i am at 34 degrees total, all in by about 1800rpm, 209/217 cam, with a 600 Holley, should I knock it back to 27? It was detonating at 36 on I think approx your 87 gas it's hard to compare MON vs RON octane ratings 🤔 thanks Bruce from NZ
@@brucew13 how do you know it was knocking at 36°? Having all the timing in before 2000rpm with that small of a camshaft is sketchy to me. Most guys dont have all the centrifugal advance in until 2800-3000rpm. If youre only backed off two degrees youre probably still getting knock and dont know it, even if you arent consistently your only one bad tank of fuel or a hot day in traffic until you will start to get knock again. You might not have that much timing, some of the mopars have inconsistent placement of the timing indicator.
If you have somewhere to do some pulls that you can record the data it will make this easier. Set up on a road where you can do a pull in without shifting the trans from like 20-60mph and get the time. Bump the timing down 2° and repeat and see if it picks up or lays down. Its really hard to get precise enough data to do anything if youre only using the vehicle speedometer and a stopwatch but its possible.
Our 87 octane is Mon+Ron/2. Thats usually RON 91. We have some superpremium fuels here but Richard is handicapped in California with R+M/2 91, roughly equivalent to RON 95.
what if the shorty headers are cericoated to help increase the exaust flow and improving exaust scavenging down low? I have my shorty headers cericoated inside and out to help increase exaust flow out of the chamber and I have noticed a good gain in low end tq. The engine is stock otherwise except a tune.
shorty headers offer no scavenging effect (the primary length is too short)-they might add flow
@@richardholdener1727 well thats a bummer. I thought by increasing the exaust velocity would help combat the lack of exaust scavenging without having to run long tube headers. but I can at least use the headers for the twin turbo build I will be doing later on.
I love when he does the good old mopar motors . Everything is ls bla bla
Nice! Great vids. Can you do a 345 hemi?
Richard....I bet the Holley HP management system is better by 40 HP...then the stock dodge jtec ecm?
Also....there was a previous comment on the 1992-93 exhaust manifolds....it is true the early stock exhaust manifold itself flowed better....they were bigger....but dodge installed more restrictive...or smaller stock manifolds along with smaller diameter y pipe to the cat....the reason for this detuning....was to cool down the exhaust to cat so it scrubbed NOx emissions to favorable levels....it was cooler....
Not gm, nice 👍
Richard do you plan on spraying it again with a carb and a plate? I’d like to see that. 👍🏻
I'm sure we will
@@richardholdener1727
Can’t wait. 👍🏻
I wish you would have sprayed nitrous first through the manifolds. Than the headers. To show the torque increase cause I have always like nitrous for the torque.
Sorry not a complaint just an opinion. Thank you for the info Richard .
nitrous adds power regardless of which exhaust you run
