JUNKYARD DODGE 5.9L MAGNUM VS JUNKYARD 5.7L HEMI-WHO MAKES MORE DYNO TESTED TORQUE? 

Magnums are some of the greatest sounding V8's ever created.

The magnum was made to pull and that low end torque is exactly what a 6000lb. truck needs. Probably the biggest benefit to having a magnum is the longevity. You cannot kill that engine. I've had mine on the rev limiter excessively and it just don't care.

Keep in mind when reading comments, most people with 5.9s have never had one setup without a stock efi/tbi setup. A 5.9 with correctly matched cam, carb, and good ignition timing setup, is unreal. Talk about some throttle response that you could put a gap on many an efi hemi off the line....

The 5.9l magnum engine responds very well to a cam swap. When I worked at Dodge back in 01, we put headers and a mopar performance cam in one, and that thing was a beast compared to stock.

Continue with the magnum line would like to see an 8.0 on the dyno

I've owned a 318 and 360 truck. I'm on my second hemi. The Hemi is def a much smoother better running engine, but that 360 did have a ton of torque. Pulled the boat with no problem at all. All good engines! 318 in the Dakota was nice also

This format with actual dyno runs and figures is perfect! 👍

i love my hemi but it will never ever have the throttle reaction and sound than my old 5.9 magnum used to have. the magnum used to rock the truck side to side when i revved it, absolute beast of a motor.

Both engines if well maintained will give you many many miles of reliability, i have an 03 ram 2500 with a 5.7 and its been one of the best truck i could ask for. Has never let me down, 210k on it now and still going strong. 5.9 is a great motor too.

I LOVE the sound of that Hemi on the dyno. Pure noise!

I own both, a 5.9 Ram single cab and a 5.7 Ram single cab pre eagle 5.7, trust me the 5.7 Hemi is way faster.

Those Magnum engines are plentiful and so easy to work on. Would like to see what porting the heads, better intake manifold and better cam would do. Basically just make it comparable to the Gen 3 Hemi and see what it does numbers wise.

I'm liking this now so it will already be there when I return to watch the full video! Great matchup!

I'm a huge fan of the magnum 5.2 and 5.9 they feel fantastic in the low end, and when you rip them hard they just seem to say "YES YES GIVE ME MORE! THIS IS SO EASY!" While the Hemi just feels like it's screaming and going to come apart any second.

Richard, you are confusing us old guys when you say "early hemi" when talking about a Gen 3. Would love to see a comparison though... 354 vs 5.7, 392 vs 392.. would be neat.

I love the intro music, please dont ever change

With the late model hemi I see more electronics and moving parts. The old magnum is a solid choice for simplicities sake. And they make heads for 360's or you could port your own.

Thanks for the Mopar content!!!

Hey Richard! started a drinking game off of how many times you say magnum or hemi. I hope it gets some more views for you. thank you for taking the time to look at Chrysler products. Its super hard to find videos on people having dyno backed numbers for anything mopar related. Its greatly appreciated!

Hi Richard. interesting video as always. I would be very interested to see a with catalyst vs w/o catalyst test on one of your motors.

I loved the bottom end grunt of my Magnum for towing.......that's where the power is useful.

I dig your enthusiasm dude. Nice vid👍

Awesome 👍 job guys keep up the great work and Builds 🤙😎💪

I had the 5.2 in my 1996 Grand Cherokee with 155,000 miles, ran 100% and was still tight as a drum, just 12 MPG city though, however long term reliability in MY opinion was excellent

Got a 360LA in my Cuda, absolutely love it.

Happy Sunday Richard!!!🔥🔥⚙️⚙️🛠🛠

Love the channel!

If you replace the choked down stock components on the 360 it actually makes decent power

Just put new heads on my 5.9L 02’ Dodge Ram 1500, went strong for 217k miles until I got a misfire, which turned out to be a 90% compression loss due to the head being cracked between the intake and exhaust valves. Lucky I had access to a 318, which run the same heads. Great truck though.

Great comparison!

Great comparison! I've got a Magnum and a 4th gen Hemi so very interesting to see the results. My Magnum is a 408ci so it's a little different having better aluminum heads too. Keep up the great work, always entertaining and informative.

I'm just happy to see a stock magnum make 300h.p.

I have a 5.9 magnum in a rock krawler and I love the torque, I use the holley sniper on it over the keg style intake, o have the hyper spark and was wondering what timing you used, I have a 727 with a 2500 stall converter and a reverse manual valve body. Just trying to figure out best tunning on it for a currently stock motor other then holley sniper and ignition, shorty headers to a 2.5" exhaust to a single resonator, and a airgap intake!

Thanks for sharing, very interesting

I'd like to see a head test of the 6.1 SRT8 heads vs the 09 newer 5.7 heads as far as flow and chamber/runner specs. How do they compare?

We want to see more magnum tests .. Also alot of guys swear by doing the keggar mod to the stock keg intake on the Magnum motors by cutting the runners on the inside of the intake for better flow. And they swear by it. So can you do a keggar mod test to see if it's true and makes more power please!?

I modded my 3.9 a fair bit. Ported heads, intake an TB. 1.7 roller rockers and shorty headers along with a Superchips tuner and electric fan. 4 hole injectors help a lot too

had a Cordoba with 360 mag and it moved well with holly 4 bl and headers /exhaust ..nice comparison

Had to turn up the volume to hear the 5.9 on the dyno, then had my ears blown out by the "hemi". Thanks for that.

Hey Richard, really enjoy your channel. Not sure if you are familiar with Utawesome Performance. He specializes in Magnums. He says stock eliminator Magnum 360's can make 500+ ft lbs. He has beer keg mod solutions (volume reducing plates are supposed to be good for 1" or 2" of vacuum at idle.) Apparently the keggers have 18" runners. I'm definitely interested in any low-end torque testing you may do. Thanks!

I have a 5.9 magnum with an airgap intake, a 650 brawler carb in a 91 rcsb dakota. It has GOBS OF torque to move that littls truck!

Can you do late model 5.7 Hemi heads on an early 3rd gen Hemi? I hear it takes some work to get it together but would love to see how it would work. Maybe even a comparison between that and a 6.4 hemi

do a magnum build to see how much you would have invest to surpass the hemi's

I’ll watch the video tommorow but I’m assuming the 5.9 makes more bottom end torque. Having owned both, the 5.9 tows way better than the 5.7. The Hemi wants to turn a bunch of rpm and won’t stay in overdrive. The 5.9 has no issues lugging around low rpm

Hello Richard!!! I have an issue. I own an 04 quad cab Dakota 2wd with the 4.7 v8. Everything now a days is for the Hemi, and that is nice and all but not everyone has the cash for all involved with the hemi. People say junkyard hemi swap and all, that is cheaper, etc, etc, but at the end of the day it is way more expensive because it is unknown the condition of the motors at the pick and pulls here and it would be a step backwards to have to do a rebuild at the same time. So I have the infamous 4.7 v8. Got it from the yard too and it was running perfect. Didi new timing chains, water pump and HO cams that I had from the previous engine that took a dump. So I want to have a basic set up for the street. Mind you this is not a race truck. It is something to have for cruise nights and shows with the wife and kids to enjoy and once in a blue moon step on it to hear that turbo spool up a little. Don't need tons of power, just something to have fun with. I have been thinking of basing my calculations of off the Ford 4.6 2v, and the 4.8 LS engines to kind of base everything out. Given my engine makes around 200/235hp with this cams I was thinking that with the gt45 from ebay it should have similar results and jump my power to around 380 ish on about 6 to 9 lbs of boost. So if there is any advise you could send my way I would really be grateful.

Love to see the 6.4l truck engine

I heard from a mechanic that vvt hemi's have a problem with excessively wearing out camshafts. He told me that trucks with 50,000 miles have come in with camshafts that look like they have 250k.

Show us early 5.7 Hemi with adapters and Eagle 5.7 intake... pls pls :)

Love my 2018 5.7!!!

Which wiring harness do you recommend for a 2006 Hemi swap since there are so many options?

Try swapping the Magnum heads for R/T Aluminum heads and going up .1 on the rockers. Question: Could you retrofit the simple Hemi VCT to the Magnum?

Hey Richard I have just about everything to put together an Olds 455, I’ll make you a seriously good deal if you feature it here!

Are those shorty headers on that hemi? Lol, liked and subscribed. Nice work Richard!

The 360 was a beast definitely love the hemi though.

I have a Dakota 5.9 r/t. It will scald tires at 45mph. But not much after 80mph. Damn good motor for torque and burnouts

The magnum head design just isn't meant for good flow. That being said, it is also probably why so many are still on the road. Just not enough power to break, and difficult to make a lot more power that kept most from pushing them as hard as other platforms. I still own 2 and believe they are some of the most durable, cheap and easy to work on engines ever made. Both of mine are over 250k miles.

Something you cant do other than put engine quest heads on the magnum or port it is cut the runners on the barrel up 1 inch from the end of the runner on the inside (to get a larger gap for air to flow from the plenum plate) and smooth the entry of the runner then smooth the entry of the throttle body. Then you can reduce the barrel volume by welding in a custom bent plate at the level of the runners. You would want to extend the ports for the hoses that connect to the throttle body and plenum down past the plate.

I like the 5.9 had one in a 2001 ram 1500 definitely has some decent get up an go

very interesting. please compare 350 and 5.3 chevyTHANKS!!

I'd like to see a comparison of a dodge 8.0 v10 vs. Ford 6.8 v10.

Oh yeah the hemi manifolds sure do flow 😂😂😂😂

Seems like you should have put the truck 392 hemi in the test. We used to have the gas options between the 5.2 and 5.9. Now we have the 5.7 and 6.4.

Curious what heads flow more: new hemi versus new godzilla. The canted valve godzilla heads flow a ton as well.

Please do some more tests with the magnum motor do small modifications to see howlittle modifications make big power on the Magnum and throw a turbo on it why don't you maybe do a turbo vs supercharger on the Magnum

So much is made of the length of the kegger manifold runners. I would like to see the difference in length between the kegger and the hemi kegger. It is the same style manifold so I just thought I would throw that in.

Literally had to replay it and make my wife listen to the hemi 😂😂😂😂😂😂😂😂😂

what vehicle was the 2006 hemi out of? a ram should have aluminum valve covers. plastic should be out of a charger or the likes? cars also had multi displacement where ram had a delete.

Ought to try getting a UTP450 cam for that magnum. I’m curious what that cam can do with the long tube headers for torque…

The 360, all day long.

My brother has a 360 magnum in a 2000 Durango. It's not a bad engine. It does everything he's ever needed it to do. Towing a 6000 lb boat. Getting to work when it's snowing and some moderately long road trips. It doesn't get great gas mileage though. I'm guessing that it probably gets 17mpg freeway and 11 around town. If gas wasn't so damn expensive,I would consider buying an older Durango. I think it's a pretty solid SUV. Probably why it gets bad gas mileage...it's really heavy compared with many other SUVS. Dang thing weighs about 6000 lbs. Another thing is that it has so many skid plates under it,you'd probably never even know if it had an oil leak or not. LOL

I have a 01 ram 3/4 ton with almost 300,000 miles on it I've only done a water pump once and a basic tune up every 5 yrs hell I barely change the oil in it and I wouldn't hesitate to drive it across country old rusty but trusty

I believe the car intake on the newer 5.7 hemi is not variable intake. The 6.4 intake is variable. Not sure why the newer car 5.7 isn't a variable intake? One of the big mods is to put a 6.4 variable intake onto the newer 5.7.

I have both but I prefer the 5.9 magnum. The Hemi feels more like a car engine and I'm not a fan of that.

Most people pulling loads will want the power to arrive before 4,000 rpm. So that magnum will be the best option for them. Probably less expensive to purchase as well.

Are you still planning on doing the piston bank to bank swap to see if it does anything on the 360 magnum?

What year was the magnum because the earlier year pre 97 ones had higher lb fuel injectors 24lb compared to later year ones at 20lbs due to emissions wondering if the early ones made more power than the new ones

I still drive my 01 ram with a magnum. The body has seen better days but you cant kill that motor.

Tip for tap, spend the extra money and buy the better goods already thrown together on the 1st gen hemi or take the extra money youd spend on the hemi and put it into parts for the magnum and make the same if not slightly more power running mostly factory parts. All about the preference and what a person budget will allow for. Bigger budget person can go for a hemi, smaller well can go for a magnum. Real question is, wtf come up with Hemi Magnum or magnum hemi etc for the 1st gen hemi decal? There 2 differnt things 🤣

Since I have an LY6, I couldn’t help but go back to your 6.0 cam video to compare. Granted the 6.0 has 6-ish more cubic inches than the 5.9 (or around 18 more than the 5.7), but with the LQ4 non-VVT cam it makes 467 lb-ft and 443 hp. It’s too bad we don’t have the LY6 with the VVT intact to see what it does. I’m not running VVT anymore either, but I’d still like to see the results. There are VVT aftermarket cams out there but no results nor tuning info. Richard??

GREAT VIDEO. HOW CAN U MOD THE KEG INTAKE. REALLY WANNA KEEP MY RT DAKOTA A 5.9. ALSO WHATS THE BEST AFTERMARKET HEADS WOULD YOU RECOMMEND. THANKS!

Really appreciate your content and the channel, once again I'm asking you to test the L-31 Vortec 5.7 with the stock injection with MPFI upgrade please?? I know you have done that with that engine carburetor installed instead of the stock injection, so many of us 55 year olds..... that don't need a LS swap, but want to make what we have run...... Much respect, 👍

Have you done testing on the gen 4 hemi with the awful truck manifolds vs longtubes?

Restoring a 64 Dodge (Ram) D200 Truck. It will have a 408 Magnum small block. Building it for torque. Shooting for a minimum of 500 plus LB FT of torque and 425 HP. There are some nice aftermarket heads for these engines that really wake them up.

I would like to know just how much power could be gotten from a gen 4 5.7 hemi. You should do a Big Bang with one.

Question. I have a 96 magnum 5.9 l It don't have a tachometer and I'm just curious is there a rev limiter? If so when or what is the redline. Like when will it start to cut power? I've always shifted off sound I try to shift basically as early as I can to get the best mpg, best I've gotten is about 12.5 mpg, but if I need more power I guess I'm just trying to figure out how much can I push it. If I were to wire a 3rd party tach what would be the highest rpm I should/could go?

Richard, I think you have all the dyno runs to compare stock 5.7 hemi, Ford Coyote, and LS (LT?). I'd like to see them all on the same graph.

The Hemi would easily match the Magnum at in torque below 3000 rpm if a longer runner intake and shorter duration cam were used. The Hemi would exceed by far if they really wanted to optimize for low rpm torque because the combustion chamber with the dual spark plugs can make MSBT with less advance. Low rpm torque doesn't depend much on peak head flow because intake tract velocities are so low, good cylinder filling is assured. It's more a function of when the intake valve is closed to trap maximum charge before the piston pushes it back into the port.

The ignition system on the hemi will break down long before the magnum

Richard this thumbnail is fighting words!

dont forget old SAE j607 correction factor (what most shops call "standard" correction) vs the newer j1349 correction factor

honestly give me a 5.9 magnum id trust it in the long run vs the hemi

Richard. Great video. I'm curious about the difference in spool times. The Magnum does well down low. What do you think?

Nice job Richard! Any chance you could do "other guy's motor" episode...the toyota 5.7 in tundras. Curious how an overhead cam 4 valve compares to the pushrods. Thx again.

Richard, I have heard the +2008 3rd gen 4.7L engines were detuned from the factory to put a larger power gap between them a the 3rd gen 5.7L hemi. They should be plentiful in the junk If you have some free dyno time.

How about a 3rd gen hemi with 4th gen heads? Would be an interesting build.

Richard: I dont have a video of the Hemi so *proceeds to do a slightly high pitched voice impression of a B18 Honda* 🤣

Would have liked a comparison between the the 2002 5.9L vs the 2003 HEMI as in 2003 the HEMI replaced the 5.9L. I bought my 2003 Ram 1500 Lone Star 4 door automatic brand new with 11 miles on it. Still have it and has 112,500 miles now. My buddy had bought a 2002 Dakota Quad cab Sport with the 5.9L automatic and all I can tell you is I put bus lenghts on him with my heavier truck. I also whipped up on the Single cab Dakota R/T 5.9L trucks. I use to mess with Camaros all the time. The Chevy SS trucks were only quicker from a DIG because they were all wheel drive as my tires just went up in Chitch n Chong. I raced a Chevy SS on the highway and was pulling on him but for some odd reason Dodge put a 105 speed limiter on my truck. I beg to differ the 5.9L pulls better than the HEMI with a load.

Magnum looks good4a Granny-Gear if you got that purposed 4x4

So can you run aftermarket efi on the magnum? Would love to do that to my 5.9 jeep

Right on
