I'm luvin this Dodge Magnum series!!!!!
Right, getting ready to build a new Magnum for my Durango
Such a overlooked motor for sure I've got almost all small block Mopar so it's interesting to see how much they'll do 😂
ME TOO
Most Non-LA 360’s are fuel injected, I realize this was a crate motor. It would be nice to see these additions with FI.
Is like to see a stock 360 magnum with a cam upgrade , and not one with a aftermarket intake and carb , try with the kegger and fuel injection.. some of us out here ain't trying to race our trucks .
A modified Kegger and throttle body with Tri-Y headers is a huge jump in torque. Port the throat, guide bosses and pushrod pinch and a 5.2 will surprise you, even with the stock cam and 9:1 compression. An SCT Tune is a must.
The 480 lift single pattern has long been in my opinion the ideal 360 cam. Gobs of torque, beautiful inclining power curve, mild cams are the ones that give you decades off reliability. Love it. Can wait to put a .480 lift single pattern cam in my 360 LA
Love this series. The magnum is dirt cheap power for Dodges and is a really resilient engine package.
Richard I'd love to see you take a v10 dodge magnum vs the Ford v10 triton, them do cam and head work to them and turbos amd see what they will take
That would be a fun one. Never heard a hot v10 Ford before. Only the viper motors.
Same here!
lot more HP than I thought it would be... impressive gains for no bigger a bumpstick than that is!
Loving this series Richard! Would love to see what the Magnum would do with a bigger cam and a good high rise dual-plane intake!
So glad that you're doing the five nine Magnum I love this channel thanks for your support
I just bought this same profile in a 112 LSA for a 377 stroker SBC I’m building for my C20. Wanted something nice and fat in the midrange with plenty of torque, but that would idle well, be reasonably efficient, and not piss off the neighbors too badly at 4:00AM when I leave for work. I feel like this is gonna be a great combo, thanks for the vid and idle clip!
Thanks for doing this i have a 5.9 in my van that i dont use for van things anymore, gonna drop it and have some fun and i know the motor has so much more potential
Yeah MORE MOPAR MAGNUM TEST!!!!!!
Just got a 2000 dakota r/t love the series it's giving me tons of ideas to make the 360 faster.
I’m ready to hear the numbers!!!
Edit: wow, that mild Cam made some serious power😶
Still loving these Magnum videos!!! Thank you Richard!!!
I have several 360 magnum engines going into cars, thanks for this very informative video.
I'm loving this magnum series
Keep the great videos coming richard! Love'em
More please. This is awesome. Dakota rt. Owner here
Excellent video Richard. I’ve always thought that the MOPAR 360 was underrated, especially here in Australia.
Cheers & stay safe guys😊
You tell em Hamster!
I'm so happy the Magnum is finally getting some AFM love.
Thanks for the Mopar dyno runs.....I've always been interested in how the 340-360 would fair against the 327-350 Chiev and the 347-351 Fords. I've used Comp Cams a lot and like the gradations that the cams come in.....seems like I could always find some cam to fill the bill in terms of what I was building.
That cam would make for a great street driver in my 96 Ram SST. I've been considering that cam for sometime and expected that it would make those numbers. My motor is stock with headers, enhanced throttle body and modded kegger. I with the kegger port mods along with an improved belly pan from Hughes Engines for possible future blower plans. I did notice much easier breathing past 3k RPM. That cam, along with shaving the heads twenty thousandths for a compression increase should go nice! Or skip shaving the heads and instead add a centrifugal.
I love seeing these magnum making good power!
Thank you for the Dodge content!! These Mopar small blocks are often overlooked, but they are torque monsters. I have one in my Duster. Love it! So what would happen with even more cam? Also are those lift numbers taking in consideration that Magnums have 1.6:1 rocker arms from factory? Keeping in mind the LA engines were shaft mounted rockers at 1.5:1 ratio. Just wondering!
Nice test! Good to see the Mopar pick up 48 hp from a cam swap. 2.5 hp per degree of effective duration. Would it make another 20 hp if you added another 8 degrees duration?
Good stuff! I am liking the Magnum content!
They’re really a good little engine. There’s so much potential to them
this is good stuff!💪 this should kind help me figure out my can options for my 360 magnum 408 stroker engine.
Honestly, really impressed with the gains, especially with the stock heads. Really interested to see what it’ll do with heads and boost. Also interested to see how all this works with the efi and the Kegger manifold
DONE AND DONE
@@BuzzLOLOL a modded kegger intake would work on that combo. It worked on my all stock 360 with headers. I noticed a nice gain in the upper RPM even with the piss poor stock cam. The cam he tested is the cam that I was already considering. That's a nice power increase that I will very much like in my truck.
@@richardholdener1727 The gains are impressive, but we need to see what happens with the biggest mutha thumpr cam you can find. Us mopar fans need to know!
@@texasgladiator4757 it's ridiculously how often they upgraded a cam to only use a laughable small cam for being aftermarket. It's like people are scared to run a big cam.
@@TheBb6prelude people do big cam test all the time. The internet is FULL of those vids. It's good to see test like this for the smaller end of the spectrum. Daily driver/performance.
Great vids keep'em coming 👍🏾👍🏾👍🏾
I'd like to see how something around 224/230 or 230/234 would do with the same setup.
Richard, you are just unbelievable. Where do you take the time for all this awesome content?! Love it!
I would have loved to see what the cam change would do with the stock Dodge fuel injection/ beer keg !
And go up with a bigger cam !
You can tailor that a/f curve by changing emulsion bleed hole sizes in the metering blocks. It does take a lot of experimenting with sizes and placement to get it correct though so not easy.
How about a 380 hp Magnum cam vs from similar specs from Comp, Hughes, etc? MP Dual Plane vs Single Plane? I'd be surprised if Dulcich didn't have an RPM Air Gap for a Magnum also. As usual, very informative, but me being a greedy ol' Mopar guy would like to see what somebody would put one of these in a hot roddy type of Dart, Duster, etc. Thanks Richard!
Theres plenty of magnums going in those types. I have the 5.2 magnum fuel Injection in my 74 dart
Ok I have a few 5.9 magnums.. so a cam will take me to 350 hp. Basically... I have mopars M1 air gap. Mopar's performance computer.... their over the counter converter (2300). So clean up some stock heads... or get so good aluminum heads.. could easily hit 375 hp....oh wait there that freshened 408 short block.......400 hp. Is possible.... but I'll be hanging on to see the rest of this great professor brings out.... thanks Richard...
With aluminum heads, a cam, and manifolds, you'd probably be north of 500. Especially if you're running it all with a 408 stroker kit.
Good video, finally just a cam test and not cam heads and intake for people with big bucks , like to see this
Test on a Ford engine
Hey Richard , big fan .
Im building a 5.9 mag with 506 lift comp cam , mild porting and 0.027 head gaskets , dual plane and 750 cfm in a 3300 lb car .
when you have your camera on the screen like this, you should turn off auto focus. your camera is hunting for focus, hence the pulsating you're seeing in parts of the video. Love the stuff!!
I have always considered factory performance cams good enough for daily driving. This cam is still smaller then the daily driven cams available from chrysler. I would consider the 340 to also be a daily driven format in its day. And they have a bigger cam. I think this is even smaller then the little red express 360. (Ill double check). Point being. The 360 crate engines came with port layouts similar if not exactly the same as the "J" heads. A square hp/torque curve is what these power plants are know for and have been proven capable to me personally . 400hp/400 torque is the optimal daily numbers for the 360sb. The 224/228 .480 lift ta cam works perfect with the rest of the same components in this build.
Glad to see ya doin' some old school Mopar stuff again. Did you ever get back to the 292 Chevy, Slant 6, 455 Buick, and other Other Guys?
Love this magnum stuff
Iv got the 20-476-9 in my RT Dakota mine is making 288hp and 336tq at the tires idk how that compares to the engine Dyno. Enjoying the magnum content
With a 15% drivetrain loss your at about 330 at the crank
@@Matp345 that's probably about right
Great video! This is my power limiter at the moment..I've maxed out on tricks without going in there. These cams are expensive!
Oregon Cam Grinding will do a high performance regrind on your original cam core.
It would be awesome to see an "apples to apples" comparison between a Mopar 440 and a Mopar 451. See if all the 451 hype is worth it.
Mmm fruit
Bigger piston, bigger stroke, more stable cylinders. Better engine
for the price? no. in a physics sense? yes.
Skip the 451, put a 512 kit in it. You will never look back!
@Cj Bert Would be cool but I need something little better than 3 to 5 mpg. Yes I know get a Prius, these aren’t for mpg I know but that’ll break the bank
Hmmm.. happen to have that exact cam waiting to go in a 5.2 magnum. Getting new heads, that cam, duel plain intake, a holly 600, and mopar ignition. Maybe it will run pretty good lol
yes I want that for my 98 ram 5.2 lol where do you order your parts from for your build?
Yes you can tune that high rpm lean spot out. You have to change the emulsion tube.
Thanks Richard!
you should do some modified kegger tests
I like where that engine makes torque!
More than I was expecting. Now to find an old Valiant with a 3.55 8 3/4 rear and have some fun. Or better yet, put it in your Nova Richard, and you can get the bowtie and the Mopar guys all wound up! Maybe some blue oval guys too! There will be riots in the streets.
Not a dodge guy but I like that you are doing more than just Chevy stuff. In my area an older dodge truck is way cheaper than a Chevy and if you want a really cheap truck, its an option
That is a cool motor, love ir
Id like to see ported dual plain vs non .. I think i know what would happen but id love to see if im right .wonder if any how much low end would be lossed vs high end gained
Hey Rich, Love to see a 340 cam in a 318 with headers and 750 carb, thinking about doing this, want power and reliability...
You can tune that with a higher end carb. Air bleeds in the secondaries can fine tune the top end.
EVEN BLEEDS USUALLY ADDS FUEL EVERYWHERE
Really cool to see some real world numbers for this type of engine. I rebuilt an old LA 360 with some Magnum heads and a lunati roller cam (similar specs to the one in this video but a little more lift), RMP airgap intake and long tube headers. It runs really good, and it made tired old van much more fun to drive. I really wish I had gone with some higher compression pistons with a quench surface, but that will just have to wait for next time. I have another LA 360 block kicking around but I don't want to build it without having a car to drop it into ... and I don't want to buy another old car to play with until I buy a house... but i can't afford to buy a house..... LOL
I have a similar combo in my Ramcharger. M1, Edelbrock 650 off road carb, no spacer. Hughes 208/214 .512/.520 112lsa. Thorley Tri-Y headers. I’m going to try the spacer.
Hey Richard! I really enjoy the testing you do. I'd really like to see you build the 360 with 1968 340 heads, cam and manifolds to compare how the differences between the 340 & 360 short blocks affect power. I'd also be interested in seeing how much power a mopar 383 would have made if they made a 383 Max Wedge.
Maybe auto vs '68 340 4-Speed cam, AVS vs Thermoquad, too. Most of us mear mortals can't/won't pop for a 6 Pack setup.
@@hendo337 the "Hoover Motor" used W/2 heads so it punched way above it weight!
@@hendo337 you can't put a 360 crank into a 340
@@Welcometofacsistube i saw some main spacers to do so. dont know where though.
@@Welcometofacsistube yep, you cut the mains down.
I'd like to see this with a Fi Air gap intake manifold from Hughes!
I put one those on my 96 Dak. Besides being able to see the distributor again, I think it really woke my stock motor up. It rev's quicker and just wants to go. Just yanked out to replace with a 5.9 and bigger cam.
WOW, 50 hp increase is sure noticeable, cam designers now sure know their job! I remember when idiots took a stock GTO with a 400 and powerglide or 3 speed auto and throw an 850 Holley on expecting big increase and all they got was a BOGGGGGGGG.
That 360 would be a big improvement over an old stock 340 in a Dart or Demon
Is there something in my coffee, or is the screen focus actually pulsing?
How about showing us the comparison of ported iron heads using the old Mopar performance templates (you'll have to make your own) vs stock!?!
Hi Richard, I'm newbie to the website but I'm not new to the otto cycle engine My father taught me theory and principle way back in 67. Why don't you test old school stuff like putting the pistons in backwards to take advantage of major thrust friction reduction thru wristpin offset. Also the 484 284 purpleshaft cam works better with the stock heads.I really admire the way that you do the tests .Thank You and keep up the good work.
piston flip is planned
I’d really like to see how far you can go with the 360
the dodge magnums were a bit more than the cam. floating pins, windage tray, and valves. I will never forget the sound it made with a broken/missing wristpin snap ring
since you always say that the heads are the most important, i would like to see the headwork done first, then add the cam ans see what its really worth over stock
Hope you do a 8100 Vortec soon!
When you gonna fool with plopping W2 heads on a Magnum shortblock?
do you think a cam like this would have a similar effect on a stock non crate 5.9 out of a Dakota R/T without any kind of heads headers etc? if so that could be a decently cheap way to fix it falling over up top
I would love to see a performance test between regular,midgrade, premium, and e85 on a performance setup. If there's a video on it someone please link it.
hey i want see these 5.9 short block with another heads and another intake dude and a better cam.... cheers from venezuela.
as far as afr consistency Does it hurt to be over carbbed For instance twin carb tunnel ram compared to the right size single carburetor
Hey there love the videos,is this the same 5.9 like I have in my 01' Dakota R/T?
yes
I would like to have known engine vacuum at idle, stock vs Comp cam. Can it keep up with a brake booster, 3 consecutive full pedal pumps? I still swear by the MP purple shaft 430/450 cam for automatics that see daily use. This is the upgrade for the factory stock 340 cam from Mopar. It'll run p/b, steering, and a/c all day with as little as a 2000 stall converter. Still works great in engines with as little as 8.5 to 1.
When are we going to see the turbo Magnum build?
It would be very interesting to see what a fuel injection system like a Holley Sniper would do VS the carburetor. Would a more controlled AF ratio make more power? One would think so but while these throttle body systems may improve drivability, they do not seem to make a dramatic change to power, not compared to port injection systems anyway or surprisingly a carb.
@@BuzzLOLOL Yes, I agree and suspect this is why there does not seem be as big of a difference between the throttle body style fuel injection and carbs as one would expect. Still, it would be a interesting back to back test here I think.
Please do more cam testing on the 5.9 and other mods to make more power.
What about taking a stock and freshly rebuilt magnum and installing comp cams Xtreme Energy 20-745-9 cam? How much power am I gaining? It's in a 1995 dodge 2500 4wd club cab long bed. The engine has heads that flow a little more than stock and I'm running shorty headers too into a 3 inch straight pipe.
Were you able to run stock springs with this can camshaft, or did you have try use aftermarket? Thanks, and love this Magnum series!
this motor had spring upgrade
Does that cam work with fully stock lifters, retainers, and springs?
It would be awesome if you could run a Hughes cam in comparison. In my experience they make much better power over comp. Those cams are designed for mopar which comps are pretty much built of chevy.
all comp cams are built as chevy cams?
@@richardholdener1727 I was told their Chrysler cams are specced off chevy with the exception of the purple cams. I could be 100% wrong. This info came from the guys at Hughes.
Ok! GM 206 rotary upgrades and I’ll subscribe
Do a 380 Magnum and see what you can get over stock!!
You should do some 3800 series 2 testing
Do you have the fuel injection stuff to put back on?
I have a 2001 Ram with a 5.2 I want to build for boost with a single turbo, what's the combination?
G'day Richard. Does changing the power valve/s make a difference to the AF & BSFC curves? I can't remember if the PV is fed from the main jet or not. But I do remember Holley recommending "V" shaped wire being inserted into the metering block ports for PVs that are too rich. Or, does is the PV operating throughout the dyno run?
power valves are all open at wot
Can you change the air correctors or does it have rods.
Stock 360 Magnum has a 249/269 - .410/.417" lift. Smog cam. The 318 has a 251/264 - .432/.432" lift and worth putting in a 360 for decent torque increase!
wonder if there would be any difference
According to my Desktop Dyno, there would be a remarkable difference. The torque especially, showing modern day Hemi torque of 420lbs/ft torque but the power looks like it drops off after 4000rpm. I wish I could post a screenshot.@@richardholdener1727
So what all had to be done to the heads for the added lift?? I was always under the impression that the magnum heads had a similar scenario as the Chevy vortec heads when it came to added valve lift?? Factory install height of 1.7?
Nothing has to be done other than valve springs, i have a hughes engine steamroller cam with a .523/.533 lift.
What is the part number for the adapter to run an LA cam in a Dodge Magnum adapter does away with the fuel pump eccentric takes up the space do you know the part number
Imagine this engine with the TrickFlow W2 style aluminum head…. It would run all the way to 6k
here we go
I am having fun with these videos. Good experiments. I have one (excuse me if you have done already...) that is interesting. Cam timing. Reason for asking - my 30 year old 340 build seems to be getting weaker, and runs inconsistent on the top end. I did a quick test of rotating the engine forward, and back, and seeing about 15 degrees of timing chain slop. EricTheCarGuy says 7 degrees is bad in this type of teset. So, I'm wondering if you have done experiments like this by retarding or advancing the cam to either decide how to set it up, but maybe more importantly know what happens when a timing chain is stretched.
Love the content, but man I really wish it still had the factory injection on it. Any chance of it going back on for more testing?
lots of kegger testing coming
Yes! You’re the best!,
I just heard of a mod using Ford 1.72 roller rockers for a 302 can you give this a try for us?
I miss my 4.7L magnum V8 it was a beast 01 Durango with four wheel drive
How would this exact same cam preform in a 318 Magnum, its mild for a 360 but would it be more of a performance cam in a 318? Would the peak HP RPM be a bit higher in a 318 application?
