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.
idk, i blew a piston into 3 pieces
exactly, my magnum refuses to die. i ran it goin 115 at redline with no fucking oil for a week straight and guess what happened. nothing. tore down the motor to the block and there's basically nothing new wrong with jt
@@spudkedir5314 I'd be ashamed to tell the world I ran my engine a week with no oil in it. That's not good.... That's why there is a dipstick.
dunno what happened to mine but mine had a shit ton of metal in the oil when I bought it. no matter how you look at it, the gen 3 hemi is just better in literally every aspect.
It literally sucked the oil out the bottom of the plenum 😂 the redline is so low I'm not surprised.
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....
I agree. Even the 5.2 wakes up fairly well even with the stock cam with a good intake and carb and headers. My 5.2 was a dog in a dodge dakota. I pulled it and swapped EFI for a Edelbrock RPM and 600AFB carb, long tube headers and a stock mopar electronic ignition with distributor. Ignition around 18 initial and 34 total and this thing will lay rubber for a block and chirp the tires into second in a 3800LB 70s dodge truck.
@@alpha13dylan I myself want to do this but I'm concerned about the transmission. It's a 46re and I have concerns about it shifting right
Swear to God my 02 ram sport was like this. Bitch had insane takeoff speed for being a pirate ship. Love the old silver bullet. I’ve drive my grandfathers 2017 Laramie and yes it’s way faster but red light to red light it was very close. Trash on gas tho
Magnum is super easy to make 400hp with a proper setup
@@neon0501 850 thermoquad and airgap on my 5.9 , night and day difference
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.
Factory cam on the 5.2 and 5.9 magnum are absolutely tiny with no lift. Cam swap is without a doubt a solid power adder for the magnum engines.
@@92clintonr The factory 5.2 cam in manual trans models was more aggressive with more overlap, timing, and a tad more lift than 5.2 autos, or any 5.9 Mag. Even so, I agree, they are all tiny. Dodge really didn't have the technology to get the dirty Mag's (lol) thru emissions w/o adding more cats and an AIR pump, something they didn't want to do, if they pumped up the compression and went with a bigger stick. Plus, they wanted these things to idle smoothly at about 650 rpm and still run PB and a/c without any trouble.
@@adamtrombino106
No sir the manual trans did not have a different cam. Ive owned 6 Dakota's all V8 5 of them manual 1 auto and tore into every single one of the engines. The camshafts are the same across the board. The only notable differences in 5.2 engines are 92 Dakota's. They have larger manifolds and exhaust diameter for a whopping 5 extra hp. After that they are identical power wise regardless of trans. Dakota/Durango RT 5.9 360 have a different cam than the regular 5.9 for another, you guessed it, 5 whole HP.
They really like the stroker crank. I was getting 436hp to the floor with my 99 408
@@92clintonr the heads and the stock intake choke it down also
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.
This format with actual dyno runs and figures is perfect! 👍
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
Continue with the magnum line would like to see an 8.0 on the dyno
I have a 96 2500 with the 8.0 and its a monster of an engine, Im with you on wanting to see a dyno.
Absolutely Love the Old Iron Blocks Still waiting to find A 2003 V10 XD
I have a 98 2500 with a v10 has 198k and still runs strong. And I also have a 14 2500 with a 6.4 and I feel the 98 still feels better low end tq. But the newer truck of course is night and day towing lol
@@mattdavis7260 that's Would Be 420 foot Pounds At 2000 Rpms If I remember correctly Lol They can Do a Burn out Of the line and still while You drive Lol
@@WTank109 definitely tq monsters
I LOVE the sound of that Hemi on the dyno. Pure noise!
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.
Iv done it myself.. suggest that you go get one lol all I'm gonna say
The funny thing is the real trick with what you’re asking of the 5.9 is the manifold coincidentally. For fuel injection its basically Hughes Air Gap or M1 2 or 4bbl unless you swap from a Magnum to an LA head. You can go that route but you have a lot more work to keep the balance of power and day to day reliability like you’ll have with a later gen Hemi.
Basically Mopar dropped everything for the Magnum as soon as the 3rd gen Hemi hit the scene so its damn near impossible to find a decent FI manifold for it as it came from the factory.
@@DrBIeed nothing that an Edelbrock manifold and Summit efi can't handle, and you have a programmable system.
@@BuzzLOLOL My 360 magnum has 440k on it. Still olds 150 compression in each cylinder.
Those are good arguments for the magnum, however given the same upgrades.... The hemi would still be victorious!!! It's just a better design, I like the magnum, but the 5.7 Just breathes better, and there is no getting around that fact. Yes a ported and cammed 5.9 would step up the game, but a ported cammed hemi would still kill it.
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 luv my 08 Ram 2500 4/4 Hemi pulls everything I need with Ease' 122,000 miles on it.
Thanks for the Mopar content!!!
I loved the bottom end grunt of my Magnum for towing.......that's where the power is useful.
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.
My friend has an 06 quad cab Hemi, and it does not like to tow his boat at all! He also has an 02 1500 club cab with a very worn 5.9. He swears the old truck will tow the doors off the newer PU, and that what he uses to haul his boat.
@@adamtrombino106 Not comparable to what you are saying, but my 06 Daytona Charger with the 5.7 Hemi just screams and takes all i give at it. First car, so it gets thrashed, 4 years i've had it, i just do oil changes with decent oil frequent, she still CAN get the advertized fuel rating on the highway and goes fairly well for having 2.82 gearing maybe 2.62 but i think 2.82 rear end gearing. I've been in one of those trucks and man yeah they just love life. Whatever works really is what is best
@@BuzzLOLOL Not gonna really argue there lol. For sure some issues, its not on every engine for sure by any means and seems to affect a small minority, problem being its not a cheap repair. Nothing against the Magnums i even like em quite a bit, just around here anything that has or had one, is far gone, and i'm not in a state to be swapping powertrains into different cars lol.
@@adamtrombino106because it has low end torque band hemi is up high so it’s got to scream literally to have the same torture as the 5.9 does at under 4k rpm
I love the intro music, please dont ever change
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.
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.
he is referring too the hemi's made before 2009 also known as the pre eagle hemi's
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.
Many people simply lock out the VVT and runners when building them, the heads are great epically the 6.4 heads
If you replace the choked down stock components on the 360 it actually makes decent power
What do mean by choked down
@@JJ-de8hg heads cam intake
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
You're absolutely correct! Great motor, poor mileage.
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.
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.

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!
I'm in
And that ladies and gentlemen is how you get alcohol poisoning😂😂😂
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.
What cam are you running in the 408? Assuming the 408 is in your Satellite? Prob using a more HP oriented cam than TQ cam…

@@MrCriminalmischief It pains me to say the new Durango is better. The 1972 Satellite gets the classic car attention and is still a blast to drive but the Durango R/T wins overall.

Happy Sunday Richard!!!🔥🔥⚙️⚙️🛠🛠
I'm liking this now so it will already be there when I return to watch the full video! Great matchup!
I’ve had built hemis, they were fun. Especially my 6.1 SRT8, and my 5.7 wasn’t too far behind that. I’m looking forward to trying my hand at a 5.9 Dakota. Has a 1500 with the 5.9 with almost 600k miles on it when I traded it in for the 17 hemi. Supposedly people are making 1000 hp 5.9 magnums and I never knew about it.
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
I'm just happy to see a stock magnum make 300h.p.
That’s all you need to cruise around and do burn outs
I don’t care cause I can let my magnum motor idle and not have to worry about me starving the cam shaft, or lifters for oil you can’t let a hemi idle for long periods of time
Awesome 👍 job guys keep up the great work and Builds 🤙😎💪
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.
we tested a modified Kegger
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
Rpm doesn’t affect all engines the same and the 5.7 will always get better mpg anyway
@@samsonreynolds3728 my 5.7 got 7.8-8.2 towing 8000lbs. I’ve never had a 5.9 do that bad
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!?
You should check out Utawsome performance, Marty is a 5.9 wizard
Oh yeah the hemi manifolds sure do flow 😂😂😂😂
Love my 2018 5.7!!!
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!
And it's a beast
Thanks and your truck is too! Are you still planning on going back to an auto? I need to put a better cam in my 5.9. I know that'll really help
I'd like to have one built to have as a backup, want a stupid loose converter and a transbrake so I can really launch it hard
@@logangaddy4917 The right Hughes cam and a small carb makes them launch really hard on the stock converter. My combo has a 3.55 gear and a really tight stock converter that wouldn't let my 273 break loose at all but after swapping to the cammed carb swapped Magnum the same gear and converter combo launches super hard. I bought a 3K RPM converter for the swap but it was bad new in the box and Jegs wouldn't help me cause I was just outside the return date. I've always wondered how it would have ran with that converter and some even bigger stickier tires. (already running almost a foot of rubber on each side.)
I went from a 360 magnum to a 5.7 hemi in my second gen ram. Also a 46re to 6 speed manual, love the truck but it has zero traction. Eventually Id like to go back to an auto with a transbrake for racing
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.
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.
@@BuzzLOLOL how can you have too many vehicles? That’s like having too much air, too much happiness, too many women. There’s never enough lol
Making power isn't just about flow and cfm, as chrysler engineers knew. Port velocity plays a huge part in making power, along with many other variables. Magnum heads, along with swirl port LA heads could support 450hp stock, no modification with the correct cam....
Charle Servano channel “probably miss spelled last name “, got 270 cfm from the intake ports on the magnum
Curious what heads flow more: new hemi versus new godzilla. The canted valve godzilla heads flow a ton as well.
I have heard the 5.7 and 6.1 heads are around 300 cfm at .600 lift and the 6.4 Apache will flow 340 cfm at .600 lift. I believe the stock Godzilla heads flow 320 CFM at similar lift but the 7.3 sports a 50 cubic inch advantage over the 6.1/6.4, and a hundred inch advantage over the 5.7. The Godzilla has 10 huge bolts per head for massive boost potential.
@@jamesgeorge4874 can we get comparison numbers for the 6.2 SOHC? Since we're obviously talking truck motors here we can't forget THE HD ford gas motor for the last 10 years? Maybe numbers for the 6.8 3valve triton too but I'm more interested in the 6.2 cammer
Love to see the 6.4l truck engine
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
I still drive my 01 ram with a magnum. The body has seen better days but you cant kill that motor.
I have the Magnum in my Dakota. It does good work at 3k but is a bit of a pooch higher or lower. It's surprisingly peaky, but with the peak in the wrong place to make motion. People are surprised to hear that my Miata out-drags the R/T. I've considered a Hemi swap, but the compatibility problems are a bear and usually involve turning the truck into a 1971 Duster that's not allowed into Oregon, or sticking a Holley iPad in the dash. I'm very confident I can match the performance with a built Magnum on stock (but tuned) EFI. And, mother of God, that 46RE auto has to go. Life is too short to put a Slurpee machine between the motor and the wheels.
I'd like to see a comparison of a dodge 8.0 v10 vs. Ford 6.8 v10.
That's a good idea! Someone needs to try that!
No comparison. Those 8.0v10 dodge motors were torque monsters. They would tow as good as a mild tuned Cummins truck back in the 90’s.
Dualing unloved "other guys" V10s? Count me in!
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.
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.
Currently have a 360 la motor with magnum heads making 450hp 500 ftlbs 👍

Appreciate it!
Hello Mr Holdener! I asked you a few moths back for pointers on installing a 6.1 hemi top end and cam on an 03-08 5.7. I was wondering if whether after a decade has past would the results be better than back in the day. I mean people, especially the truck guys have dialed in these combos eons ago ( cam timing, and ignition.) and all the ifo is out there.
Well in my hunt for parts, I came across a 6.1 hemi. After wheeling and dealing. I asked the seller to pull the heads, and sell those for himself. What I ended up with was a 6.1 short block for $1500, that includes shipping. It spins well, and the lifters look good. I think I got a okay deal. But, I do need to do a deep dive to be certain. Except, Unfortunately I can't test to see if you can do a good build on a 5.7 using only factory parts. This is okay, since out in the middle of coal country, tuners are far, and few in between. So building an SRT8 clone car is a safer bet. Thanks for your reply.
why would the results be any different if the parts are the same?
@@richardholdener1727 So I'm generally talking about the at home build. The recipe book seems written. As I read forum posts from back than, 1st people installed parts, and than had the tuner do his thing. Later people started advancing the cam 4-6 degrees, and it seemed like everybody followed suit the result seem generally good for heavy vehicles. Other people began to use heat insulators on the aluminum intake, at the same time specialty CNC porting became widely available. Today, I think it's MMX that's making a computer box to allow the use of the variable runner intakes on older cars.
It just seems you could score a wrecking yard motor, and do a build with just swap meet factory parts with less hiccups, and get pretty good results due to the fact that the pioneers laid the ground work.
Do you remember when mopar would sell paper templates so you could port their cylinder heads?
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
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 drive a 2000 Durango rt daily, it gets 11.5 combined mpg. Thing is a monster towing especially for a smaller truck, and it’s pretty quick against other trucks and old mustangs
Great comparison!
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.
If you're going to add the 6.4L truck Hemi he may as well also add the 8L Magnum since both are 3/4-1 ton engines
@@lb9gta307 True, that would be a cool comparison to see.
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.
Forgot to mention the part were the 5.9L is generally a much more reliable engine than the 5.7L Hemi. 5.7's love to eat camshafts and lifters.
My only Experiance is with my 97 ram 360.
440k miles and the thing runs like a dime. still makes an impressive 150 dry compression in all cylinders. Love my motor.
Only the mds equipped engines eat cams , but the problem can be solved by disabling the mds system . gm's ls engine has the same problem .
@@HowardJrFord Non MDS equipped 5.7's have the problem too. The problem is lack of lube going to the roller lifters and camshaft.
The MDS lifters specifically is kind of another issue along with the MDS system but this problem had been persistent even in 2004 engines. The LS and the AFM system was a different problem also involving the valvetrain, however yes both AFM and MDS are trash, thank the EPA for that bs.
The 5.9 Magnums are more reliable. Some might say...unbreakable....provided you religiously change oil and maintain proper. Which some people do not do....Now if they just didnt have that pesky belt squeak and chirp. Although mine does not anymore probably because it only has about alittle less than 20 thousand miles on it rebuilt.....I believe was attributed to power steering pump pully.
@@jonathanfreedom1st I have a 98 Dodge Ram Van 5.9 with 200k miles , oil has been changed a 100x owned since new
that’s another thing I often wondered why did dodge use the 6.2 instead of the 6.4 for their hellcats and demons? I’ve only seen the 6.4 in the trucks.
I’ve got a question for you, and I don’t know if anybody’s ever asked us airflow comparison on heads what flows more the eagle heads LS heads or the coyote heads? I wonder if you would happen to have any of those stats
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
Literally had to replay it and make my wife listen to the hemi 😂😂😂😂😂😂😂😂😂
honestly give me a 5.9 magnum id trust it in the long run vs the hemi
Love the channel!
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.
So a super new design compared to the magnum would do better? Shocking lol
what does MSBT mean?
@@evanc6110 Minimum Spark advance for Best Torque
The Hemi is just a better design.
Cam a hemi vs a 5.9 cammed, and the hemi will still win!!!
Thanks for sharing, very interesting
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 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.
The 360 was a beast definitely love the hemi though.
How about a 3rd gen hemi with 4th gen heads? Would be an interesting build.
agreed
I like the 5.9 had one in a 2001 ram 1500 definitely has some decent get up an go
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 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!

@@richardholdener1727 Hey Richard. For whatever reason, after much searching, I haven't been able to find the Kegger mods video. Could you please provide a link or the specific name of the video? Thanks!
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
one thing not in this test is fuel mileage...the hemi almost doubles the mileage of the thirsty 360 and with almost $5 gas that's kinda important these days
True, but a lot of that is due to much better transmissions too. The old 4 speed auto that the 5.9s were stuck with were not only huge power sappers, but very inefficient. Even the 5 speed auto with double OD was better.
@@BuzzLOLOL I want to install a ZF 550 nm 8 speed in my ol truck , but they say it needs s engine controller to talk to, They left so much $$ on the table not making one! there transmission is ? 40 % better than a a550
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.
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 🤣
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…
I ran that cam and honestly other than a sweet sound,I really couldn't feel any major difference although I never put it on a Dyno to actually compare
@@joewithhart157 I was using my 5.9 frequently for towing, and occasionally in steep grade snow/ice/gravel when I was looking into them. Never pulled the trigger on the cam though.
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.
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 dont have a video of the Hemi so *proceeds to do a slightly high pitched voice impression of a B18 Honda* 🤣
I have videos of Hemi-but I'll stull do the noise
Show us early 5.7 Hemi with adapters and Eagle 5.7 intake... pls pls :)
The ignition system on the hemi will break down long before the magnum
very interesting. please compare 350 and 5.3 chevyTHANKS!!
“”Battle of the V10’s !!!””
What an epic battle to discover what these behemoths have and are capable of. Turbo or supercharged!! Yikes!!! Ported or aftermarket heads? Timing and tuning. Watch out!!!
Ram vs Ford vs Viper vs Srt
had a Cordoba with 360 mag and it moved well with holly 4 bl and headers /exhaust ..nice comparison
dont forget old SAE j607 correction factor (what most shops call "standard" correction) vs the newer j1349 correction factor
that doesn't matter when we are testing them in the same manner on the dyno (or the rated power outputs)
@@richardholdener1727 it does if youre comparing them to OEM advertises numbers
my 5.9 ram 03 has 244k miles original with engine. still runs good no smoke unless when revving it high but this trucks aren't meant to floor it. lol
The 360, all day long.
I be racing them hemi guys errday lol
@@mariozavala93 and Losing.
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.
Magnum engines respond extremely well with a simple cam swap it's a night and day difference
absolutely, my 360 LA with a custom ground cam and ported iron heads gained over 200hp from the factory. I love me some small block Mopar!!!
The 360 was originally released as a more efficient motor (for the time) and is extremely choked down. A few bolt on parts like a better intake manifold, better heads and exhaust and a mild cam and you can easily get around 330hp out of it
@@jeepstertj556 I have a 81 Block 360 that has a custom ground cam, late 70s high compression non smog heads off a diplomat cop car that have been ported, an edelbrock rpm air gap intake topped with a quickfuel 750 and some long tube headers and it makes a bit over 400hp to the crank. 360s respond super well to upgrades. Didn't cost me an arm and a leg either and she's a 6500rpm screamer
@@jaymoe5.7 I did my 99 360mag into a 408 stroker back in 2001. I was getting 436 to the floor. I was in tech school at the time so I did most of the work myself
@@jeepstertj556 that's awesome man! I'm in the process of turning my 360 which has been bored into a 372 into a 408 stroker (would actually be a 420 stroker with the .60 overbore haha) and getting some aluminum heads and a 150 shot plate kit for it too. I'm shooting for 550 on motor
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?
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.
DETUNED?
@@richardholdener1727 detuned may be the wrong term. A good bit of power was left on the table either do to emissions, reliability, or marketing on the 3rd gen 4.7L. There are OBD2 tuners out there claiming 40-50hp and +50ft*lbs gains, I know those are best overall gains not peak but I bet it's still a noticeable improvement. For comparison, the same companies are claiming 10 - 15hp gains on the 3rd gen hemi.
Who needs a magnum or a hemi when you can get a cummins
I’ve seen more 5.7 hemi blown up with under 100k than any other truck engine no matter what brand
Think you will ever do a video on a 8.0 magnum video
I'VE ONLY EVER SEEN 1
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.
the gen 3 big bang video is up
@@richardholdener1727 gen 4 has better heads and vvt should make more power at all levels right.
So in summary , an eagle headed hemi will put up similar numbers to a 426 street hemi
a stock 426 street hemi probably makes more than 426 hp
Are those shorty headers on that hemi? Lol, liked and subscribed. Nice work Richard!
stock 6.1L SRT8 exhaust manifolds
Those stock 6.1 manifolds are basicly shorty headers being a welded individual tube design.
i have a 318 and 360 fuel inyected i like them a lot, more of 300k miles and they run like new
