Hemi builder here.... throw some eagle heads on a pre eagle engine with a .40 thou head gasket and that same cam and you'll thank me later. Compression ratio jumps to 11 too!
Hi Dale..how are you mate .I'm Adrian.in Australia .got a couple of questions..I bought a 2006 gen 3..I'm putting it in a Ap6 valiant.split grille ..like a barracuda basically.Aussie version..anyway...how much do you know about the msd hemi 6 ignition module .and the fast ez efi system.and if familiar with them..would you recommend..or have similar products you'd recommend
I have a 2000 Jeep Grand Cherokee (WJ) that is my beloved project rig. I do not like the 4.7L V8's that came in those and I am _going_ to swap in a different V8. I'd like to keep it Mopar (too many LS swaps out there already). I was going to ask in the comments if the Eagle heads would swap but, you just clarified that for me. I'm also considering a 360 Magnum. A strong, low RPM idle and off idle torque are far more important to me than upper RPM horsepower. Do you think a stroked Magnum would be best for me? Or a Gen3 Hemi?
I just wanted to say, thank you. Now my head is spinning with ideas. SWEET! . . . do you have a channel or website? . . . greetings from Alaska.
@@RANDOMNATION907 Just swapping Edelbrock heads, and a small cam into a 360 can add a ton of power to them. There are couple mud rigs in my local offroad group with Edelbrock top ends on carbed 360s. They are beasts!! Plenty of low end and top end! Very simple old school setups
Wait so the eagle engine doesn’t come with eagle heads?
@@mannyalvarez6057 Of course they do. What are u talking about
When Steve Miller wrote his biggest hit song, “Fly Like an Eagle” He was thinking about the late-series third-gen Hemi.
True story.
Lol
Time keeps on slipping...slipping....
Here's the hilarious thing, they basically dogged the early 03 to 08 Hemi for not making power, YET in their Hellcat Hemi Power episode their 03 to 08 Hemi made almost 500 horsepower naturally aspirated before they slapped the procharger on.
I really don't know how they screwed this test up when Richard Holdener already did this test that they basically re-ran on the same dyno.
The answer here is get a 03-08 hemi block , 6.1 crank with eagle heads with the 6.4 intake manifold , you got a perfect 5.7 hemi to swap in a Miata
And don't forget a hellcat 6.2 blower 😉👍👍
@@jakey20022 they’re not really efficient, just get a whipple and be done with it
we've ran oem coils over 1,700 horsepower in a Jeep that went 8.0 @ 174mph in the 1/4
Yup msd coils on Hemi’s are a joke. Most modern msd is really
@@tomlin19 you know if they would be an upgrade for the 3.6l pentastar? I need new spark plugs
@@mails5054 from personal experience and Dyno testing. Stock coils and plugs work best. Coils are just going to be an unnecessary expense and they don't have the durability/longevity of the OEM. When shopping for plugs, if you're not using nitrous or a supercharger or turbocharger stick to OEM plugs. Even when guys run those modifications most of them stick to the same design and manufacturer plug that came out, they just have to use a cooler heat range. The engineers did their homework to make the most durable and consistent performing engine they could. Also in my experience, running an "upgraded" plug that's made out of a different material changes the resistance of the plug (usually decreasing it which means the coils have to work harder) causing intermittent drivability issues and premature coil failure. Don't fall for the gimmicky claims about ignition.
@@FreeRiderNeal ty, i have 0 plans to modify my engine because i run a snorkel. I'll stick with my oem coils when i get new plugs for my 3.6l
I can finally relate to one of your shows. Thanks for the working man’s engines.
Next needs to be the shoot out between the 392 and the 5.7 hemi to see if its worth the extra bucks!
You mean the 6.1 and 5.7. 392 is a brick
@BayBuilds427 nah, it's a great NA engine, the pistons and rods just don't like boost, besides, you can throw a 426 kit in one and make alllllll the boost you want
5.7l hemi
But best is 6.2l hemi
Unless you want helephant
Overall 392 trash vs 5.7 or 6.2 block
6.1 boosted
I had an 08 pre eagle engine with ported heads, long tubes, and a custom cam with the same lift you used and 214/222 duration at 112LSA+3° ground in that laid down 360hp @5500 and 360tq @4500. Bone stock the truck laid down 260hp@5000 and 275tq@4200. That's roughly a 100rwhp gain and if you do the back math to the engine that was rated at 345hp and 375tq, it's producing 477hp and 477tq. I think y'all probably chose the wrong cam and the carburetor was a poor choice vs the stock EFI and manifold. The answer is still unequivocally yes, the eagle engine is superior to the pre-eagle engine.
or spend a lil more go eagle and start at 320hp to the wheels and with those same mods you listed 400+hp to the wheels
I feel like you could of given life to the 03-08 hemi engine I've seen some people swap eagle heads and put a 6.1 intake and swapping out the lifters as well. For sure hands down the vvt hemi is way better performer. But I think for some of us who don't got all the money to run on swapping out all the wire harnesses and getting all the computers etc just to run the vvt hemi only speaking for 3rd gens I'd still stick with the previous 5.7 and do the head swap. With 6.1 intake. It be cool to swap an 8speed with the vvt in a 3rd gen but I think it's a lot of trouble and more money to do. But can be done though. I've seen a guy do it on a 3rd gen 2006 swapping in a 8speed trans.
4l80e swap all day
@@John-4649 what 😆 your talking about a transmission. I'm talking about an engine. Oh but I see your reasoning. True doing that swap alone gets them moving. The trans swap is cheaper and they can get built much beefer. Cheaper than building the 545rfe. Or doing the 8speed swap lol
@@mopardude707 I should’ve been more clear 😂 I was referring to the 8spd trans part of your comment! I’ve had to rebuild my 545rfe once already and I’m sure it’ll implode at some point soon. I’ve been researching the 4l80e swap and that’s definitely the way to go if you don’t want to spend an incredible amount of money on a sweet 8spd swap!
@@John-4649 yup I totally agree man 👍 I did understand you lol I was the one too that didn't read my own comment that I had mentioned about the trans part. But for reals. Cheaper solution tbh
@@mopardude707 lol I’m patiently waiting for my 545 to give up the ghost AGAIN before I jump on it
But on the pre-eagle hemi as long as you watch your temperature, they’re the most reliable, hemi, besides head gaskets here in there
Yep!... That is why I purchased a 2019 RAM 4x4 5.7L on purpose. The only things that I would change is to put headers on it, 6.2 oil pump on it. My tires are Wild Peak's and have not had any problems at all with them (Great in the snow)! I have about a 1.5 - 2" lift as well!
Don’t forget a 6.4 truck intake manifold, better then the 5.7 truck one.
6.4 manifold fits on it gives it a lot of help👍🏼
My 06 Magnum RT with just Borla exhaust and Diablo tuner ran neck and neck with my brothers stock 2012 Challenger RT. Surely my basic mods didn't add 100hp to my Magnum? So they aren't very far apart in a real world "installed in car" situation. Maybe your older 5.7 is a bit of a dud? Anyway, great video! Thanks giving the 5.7 Hemi some attention!!
The one thing i noticed in the dyno results was the 03-08 was, it had better torque under the peak than the eagle hemi. As the old saying goes, Torque moves you better, but HP sells better
@@crazylarryjr Im a big fan of the older version. They respond so well to mods. Especially a full exhaust and a tune
To fit either foolinjected engine to an early car is that you need at least the computer they come with. Then you have to wire it into the car. Expensive!
Using a Holley set up is more expensive and doubtfull any better on a stock engine.
My suggestion is use a carby 360 with good aftermarket heads, carb and ign. And it should bolt in.
The same with SBC V LS in a GM scenario. By the time you buy everything to fit the LS spend the same money on the SBC and it is as good. And fits the car!! The only adavantage is the weight of the alloy enegine,,, but people are not using them!!
The later efi engines are excellent in a car they belong too. Though it costs plenty to extract more power
I'd love to see the apache (392) just built stupid power N/A vs forced. I have a 2019 charger 392 ScatPack. "Allegedly" direct connect is bringing back the hellephant and will install it in vehicle without voiding warranty. And MMX has a 426 (hellcat/392 iron block). Of course I would be looking for a difference on build with VVT phaser lockouts and MDS delete (programmed out of an unlocked computer) vs what dodge would "allegedly" install.
Not that I could afford this, but just to see.
That's badass.. love the 6.4 engine
Great vid, running a still unused brand new 6.1, aftermarket Link ECU, and a few custom addons I feel good HP to be had out of her,
A couple hundred dollars for a 400hp 383tq engine......sounds like a win honestly.
you're telling me oil pan, coils(which arent necessary), intake and carb cost $3440? math dont add up.. if junkyard pre-eagle is $400??
But yeah just take eagle heads, 6.1 alum intake, and cam and put it on 03-08
I want to see the gen 3 car vs truck 5.7 I'm having to do the swap now from my wreaked 04 ram to my 06 charger RT
Nicks garage just did a stroked 318 thats put 400hp thatll smoke that o8 hemi
Yeah, until the mds solenoids round off a cam lob and cost you 4 grand in repairs the eagle engines are greeeaat....
I've got 2 cams to replace at work
All Hemi guys choose not to believe seized lifters are a thing. Even when it happens to them. Had 3 hemis and all had lifter failure.
@@user-qn6uz7wm1t It's a problem on MDS motor due to the solenoids cutting off oil to the lifters. Non MDS do not have the same issue. They are the same block, but the plugs in the non MDS flow oil to the lifters at all times.
@@carllmack2287 yes they do. A manual non MDS 5.7 will still have the same issue. Confirmed from my tuner that specializes in hemis
My 05 dropped a valve seat.
Did they upgrade the camshaft oiling so it does not eat camshafts?
I love the way my hemi sounds but I'm looking for it to sound like a pair of dds bouncing in my face that's were the cam upgrades come in
I think a lot of it is what are you using this engine for, I mean if you are building a truck to work with I think the carburetor one would be fine and not break the bank.
What about the 6.1l hemi out of a 2007 srt8 charger
I have one in my 68 Charger at the moment... basically just a stock engine. I am building a bigger play thing... 7.0L stroker with some boost.
@@BBCharger5spd that's awesome
Trying to put a 5.7 hemi in my 99 silverado
It would be easier to put one in a Dodge Dakota second gen
I have a 2010 challenger rt 5.7 manual so no vvt. Would it have the eagle heads on it?
What happens if you modernize an old 426 hemi aluminum heads and fuel injection I'd like to see that!
It makes a little more torque...that's it. You need an IR setup to advance a Gen2 hemi
The thing is hemi or gm or Ford , new school vs old school, it all about cost, small cost big cost, lol you can make 1000 plus go out of any of them lol I thought Is old school still cheaper and bit stronger engine do to the better mental
Anyone know if Dirt Everyday is making new content? I spend my hard earned money for the motor trend app and they don't have the common decent see to answer an email from a month ago.
I'd rather have a coyote or 4.6
Coyote, 4V 4.6, and LS/LT engines are much better choices. Couldn't pay me to drive any modern hemi car, they're junk.
@@mr.horsepower8125 I totally agree basically anything dodge except their cummins diesels which arent dodge
LS LT Coyote> Hemi
Old video, they don't have half price day anymore.
?? Dependability???
Lots in junk yard
Boosting that carb motor might be better dollar for power wise.
We need the return of engine másters here on UA-cam and the full episodes here pleaseee
I agree. Now that you can't watch it outside of the US
did he add in the cost and wait times for the EFI system to run it? also the best bang for the buck would be eagle head swap early hemi.
That's the path I'm taking. I have an 05 long block and harness and a set of eagle heads I picked up for a steal.
How much was the ECM, throttle pedal, harness etc to run the EFI engine??? You're leaving some of the most expensive pieces of a EFI Hemi swap out of the equation. The ECM and the tuning "De-Bugging" after the fact are not cheap as far as I am aware.
6.1 is king of NA hemis…. Prove me wrong
Only problem with that engine is the valve issue
No the 392 is they have more stroker/bore options.. 6.1 is the king of boosting its the only hemi that’s forged from the factory besides these new hellcat blocks
@@Nunya-js6cy The 6.1 and 392 both have forged cranks; and hyperutectic pistons.
I have a 2017 6.4 Crate motor with the stock intake on a Holley Terminator X computer - ported heads, upgraded cam, upgraded lifters + springs... put out 615HP @ 6700 and 553 Tq @ 4600. Folks, do not underestimate the stock intake! The torque curve is extremely linear with the short / long runner hybrid design.
yes! 318 build please! hopefully a magnum
The Eagle Headed Hemi is still underrated imo. It's the perfect swap if you want to improve an old 6-cylinder Challenger/Charger/Barracuda/Valiant while keeping it in the Dodge family. 470-500hp is more than enough for a chassis of that age (might even need some additional bracing), and it will sound and look the part.
Sound?. Yes
Look? No
@@Welcometofacsistube, that's true, but the 426 Hemi was the only beautiful engine from Dodge of that era. The 440 six-pack looked decent as well, but their smaller displacement engines just weren't that visually attractive. 😬
@@flyingphoenix113 disagree
and Im I can come see if I can get a ride to you
The eagle 5.7 only made 385hp so it would need some extra parts to make them scat pack numbers
Thanks for doing this comparison, it was super interesting, I thought it would be a lot closer than that! I remember when I got my Challenger R/T back in 09 I went to a car show with a friend who bought a 07 Charger R/T and he was complaining that his 5.7 felt kind of slow all I could remember thinking was "man what are you talking about this engine is a lot of fun!". This comparison just shows how many differences between the 2 engines there really are! Now having done a cam swap/headers and 3" exhaust to my eagle 5.7 I've got to say it's 10 times more fun than it was back then. Great engine, great comparison, thanks for the video!
I know I am responding to an old post but..
Remember his Charger had 2.82 rear axle ratio..I had a 09 Challenger RT 6 speed with 3.92 gears,plus the transmission gear ratio was lower for the 6 speed making it very quick off the line..The new 8 speed has a 4.71 first gear making it the best for performance! Albeit 2015 and up..i had a Charger Daytona with the 3.06 gears and had a little more hp than the regular RT,my Challenger was a daily from 09-16 with 185,000 trouble free miles..My nephew bought it from me(stole it lol) he ran it to over 200,000..He sold it for a new Journey RT awd for the wife as they had a kid,hey they were 22 at the time.
Yep throw on some eagle or 6.1 heads, flow is nearly identical, slight edge on the intake for the eagle and slight edge on the exhaust for the 6.1 heads and both raise the compression on the early motor with no VVT to worry about and the block and rotating difference are negligible. If your planning to stroke one really makes no difference besides the eagle version is now easier to get aftermarket parts for. I'm in the process of getting parts for a 396ci stroker pre eagle with ported 6.1 heads with claimed 370cfm on the intake side with compression in the 10.5 - 11.0 range with 237/251/113/+3.5 camshaft and a ported 6.1 intake.
I disagree, yes the 2003-2008 is down on power, but it's far far cheaper. Sitting stock, it makes better torque earlier, swap in a set of Edelbrock heads and the 03-08. you might pick up 50 of the lost 100 HP. If you get the 03-08 with computer, wiring and everything for 400-1,000 dollars, do the same cam with Edelbrock heads and a proper oilpan, this could be a solid streeter in a midsized to early small car such as a Volare/Aspen or a Dart/Valiant. Honestly the early gen 3 hemi's had possible issues (didn't always happen, but enough for concern) with exhaust valve seats popping out, you need ahead swap anyways, may as well get a set of Edelbrocks or any other performance based decent priced head. Not a huge fan of VVT anyways, if i had it i'd be eliminating it, so for a streeter with occasional drag runs, the older one would be perfect for me
I was thinking nearly the same thing. This wasn't a fair comparison IMO. The Pre-Eagle engines need some modifications to keep it an apples to apples comparison, mainly better/aftermarket heads, and a better cam choice. Both engines need spring upgrades, which most everyone does with a cam swap regardless. At the end of the day, They compared stock for stock, with an improper cam swap. If this was done correctly with proper springs, Both engines would make a bit more power, and the Pre-Eagle unit, give a fair cam swap, would have done a lot better. Still not as good as the Eagle but better.
That modded early design looked like it had more juice at the low rps. So if you were daily driving it and not drag racing it, looked like a decent bang for buck.
It's perfect for hot rodding old trucks that came with less potent powerplants. Gobs of torque from very low RPMs. Just don't expect it to do anything when you rev it out. 😅
I guess it depends on what your baseline is. If I was considering a Hemi swap, it'd be in my Dakota R/T and the stock 5.9 already has the torque covered pretty well. Same would be true for an older Mopar with anything bigger than a 318. I think what makes the Hemi worth considering as a platform is that high-end breathing. If it's not going to spin then I don't see the point of choosing a Hemi at all as opposed to low-buck LA or Magnum motor.
Also, the big thing with the modded Eagle motor was they put a bunch of cam in it. The stock one really did have buckets of torque everywhere. Personally that's the one I would choose, just so I didn't have to tear into the thing. Although what I'm REALLY going to choose is to keep my stock 5.9 because I'm poor.
Far too many differences tp call it a comparison. EFI to carb, much different cams (.600+ on one to .520 on the other) VVT to adjust cam timing. More like Apples to lemons than apples to oranges.
It's like comparing lap times from a Ford mustang nascar to a regular mustang. Not the same.
The earlier model was basically at the limit of what you could do with it (excepting EFI). If you put EFI on the 03-08 would it make up the 100HP differential? And don't forget, you can't put a bigger cam in the 03-08 - it was already maxed out.
Not apples to apples for sure but I feel the point was made that the 03-08 is cheaper but tops out way sooner than the eagle version of the GenIII.
@@bgausden I would have been more interested to see them take the Eagle motor and drop a similar system to the older model and see what it did as a more relevant comparison. You can lock out the VVT which would cost top end power and torque, but would have been rather close to the EFI. EFI on both, carbs on both with the same internals would have made more sense IMO. Reminds me of their Windsor vs Cleveland comparison they did where one was a mild motor and the other a stroker kit with more cam and aluminum heads. Yet, as with this it was a comparison LOL
Exactly
😂😂 yep!
Also, I buy eagle engines pretty regular for under 1200 bucks. I've paid 1800 for a 392 Apache before. I have 6 392s out back and several more 5.7 Eagles.
Sheesh how do you do it
Let me in on a 392
How much for a 392?What’s your location?
Have you ever put one in an 04 f150
You have anymore of those engines?
You can still pull early 5.7 yourself from any LKQ for $300
Any real comparison should also include the price of the engine management, fuel system etc required to run the engine.
Agreed 100%
Without that it is not an accurate comparison.
What about the self learning EFI kits that mount like a carb, im amazed engine masters haven't experimented with those
@jake bannana they didn't use it on this video though, hardly anybody uses carburetors anymore
@Lacy Gilmore they seem to have all their [power Nation franchise] based off carbs. It is faster to build without showing vehicle specific engine management. They give a baseline figure for "no prep, 1960's racing" and can get more power on dyno without heavy fuel management.
All the engine builds where they show "and it comes with pre-cast holes for fuel injection, if you choose to go that route, but we're opting for blah blah blah carb", it would be nice to see a build where they actually used them, and built a motor to go into today's muscle, as there is not as many yesteryear vehicles [left] being modified.
I've been a fan going back to when peterson4x4 mag had diy tips (go to junkyard and get this part) before switching out to paid ads offering same thing for 10x price. (More than 20 years) I can attest, this is going to be their peak before EV's take it away from me.
The upside I can see on the 03-08 is grabbing one to build with my son for his first engine. It's cheaper, and not as much power (as he's learning to drive). Otherwise......
Cheaper is the number one reason. There alot more things that apply to than just an engine that wasn't mentioned. Like wires harness all the computers and sensors. Etc alot of trouble. On the long run I think you'd waste more money on buying the vvt for a swap. And honestly you can swap the eagle heads from that vvt hemi to your magnum hemi. And use a 6.1 intake and lifters. To get some more power out of it then you'll be able to run a bigger cam instead of a small one.
You can make eagle power with the early hemi no problem. But you need to take the current tech and apply it to the older engine. They are extremely similar motors where one is base nothing too it and the other has a lot of upgrades. The differnece between the two is the heads. On my 06 magnum i put down 396 ftlbs at the wheels with only headers. But on the flipside only 341 hp. 396ft lbs at 2500 rpm is fun! It just falls flat at higher rpm.
@@Sak-zo1ui Here in California, super RPM is useless on a cruiser. You don't need ultra high revs for traffic jams.
@@michaelbenardo5695 yes. But a square motor perfect. You speed across the entire midrange. That is what I would like to work towards.
For that cam the phaser limiter should be locked and valve springs are required to be upgraded. Also mds system must be deleted
03-08 hemi needs efi, cnc'd big-valve heads, better springs, titanium retainers, bigger cam and some tuning. I think Freiburger would be impressed with my 04 5.7. Makes well north of 500hp
Also should add the BGE trucks and later hemi cars came with. Beefier block all around
So what you're really saying is that even the legendary 340 is a, wait, what was your word..."POOCH" compared to the 2009-Present Hemi. Because a 340 with a cam and bolt on's, using stock cast iron "X" heads, typically only made a little over 400hp.
As one would expect from 50 years of technological advances. 340 should still be held in high regard for what it was at the time
I feel like an even close to normal comparison would of been EFI 03-08 vs Efi Present motors with the same upgrades. As some people said, you can Swap the later EAgle heads on newer motors, one guy here said throw a 40 thou headgasket on and you can put the same cam in the earlier model with those new design heads. Obviously its not the most powerful, but in terms of a swap engine, its not the worst by any means. 400 bucks and you could honestly just put it how it is.
I wish you would stop using this .050 start lift, it's not realistic. Use a .005 or .006 start lift it's more real world camshaft specs.
What
Built 318 vs hemi? I'm down!
It's far better than my '76 360 making well under 200hp. I don't have a lot of cash and I think that the early model is perfect for me.
Your 360 has a lot of potential as well. Don't under estimate it. Carb and intake, headers, cam, ductile iron rockers, that little 360 will wake right up.
The hemi's high intake port angle vs the lower ports of the dual plane is horrible. Junk like that should not even be sold.
What about carb on the eagle engine?
Have you guys tried the VK Nissan V8 yet? With a set of springs and retainers they’ll rev to like 15000
Granted they’re dohc so a little more complicated.
Ha. No. Stop.
So if I have a 2003 5rd Gen E.F.I.i have an eagle??
Nope.
The stock eagle is underrated! 395hp from factory but they proved the stock engine is dynoed at 439hp!
No, factory HP ratings are NET not GROSS. Meaning they are tested with all accessories being driven off the crankshaft. On the show, they are using an electric water pump, with no alternator, A/C, Power Steering etc.
Don't forget Mopar also geared it way down, 2.86(?) If i remember correctly! We installed SRT 3.06 and that alone gave it a much better "HotRod" feel. I have vid of my buddies vvt 2010 Charger R/T SRT gear swap, cai , catch can, mid pipe delete,tuned .
Against my 2005 eagle intake, hand ported to match intake, exhaust, same gear swap.
It wasn't even close!! My 2005 would punish his 2010 Charger R/T vvt .
@@BRob1320 my 2014 Charger is geared 2.65
Thank you motor trend for the full episode 🙏🏻
This isn't the full episode. It's the meat and potatoes of it. The full episode is 35 minutes long. But ya, you're not missing much.
Wait a minute here..... I just rebuilt my 1969 440 Engine, nothing fancy at .030 over ?
but with Forged Flat Top Pistons, ARP Bolts in the Rods, splurged on a set of STEALTH Heads for $1,000 Bucks then another $500 for Pocket Porting/Back cut Valves and redid seats, XE284H Hydraulic Flat Tappet Cam and topped the whole thing off with a Holley Street Dominator/850 cfm Holley.
Made 525hp with 520 Ft/Lbs Torque all done by 5,500 rpm !
SO MY "KEEP IT SIMPLE STUPID" 50 YEAR OLD 440 REBUILD.... ABSOLUTELY TROUNCES EVEN THE EAGLE HEADED GEN 3 HEMI BY 25 HP AND 70 FT.LBS OF TORQUE ???????????????????????????
Forgive me for say'in so....
but why not just leave the Gen 3 in the junkyard where it belongs ??????
$3840.00??? How do you possibly get to that number with the carbureted engine vs $3066.00 on the EFI engine? Something stinks here.
Converting to carb raises the price
I'm seeing they added $650 for the carb to the pre eagle but none of the high dollar computer engine management sytem required to run the eagle. Not an apples to apples comparison on cost.
@@chasmilner3178 Exactly. They left out so much from the cost of the EFI engine just to make it look more appealing.
Wait I’m confused I’m confused why is the eagle hemi over 400hp I thought it’s 330 at wheel and 390 hp and 300 for pre and 360 crank
Yeah, No... I'm missing something here. Hiw us a 500$ carb the same cost as a 2500$ EFI set up?
Then add a high pressure fuel pump that can take 600 hp and THAT adds more cost. Then computer engine control that is not needed on the carberated engine.... No Way these are the same price.
If I'm building a budget, cool, lightweight ripper that only needs 400hp and maybe a little tickle of NOS to make 500hp.... and it's a "Hemi" ... that 400 dollar long block would be my #1 choice.
My 03 5.7L is still strong, not quite like it was new but still has enough punch for me. My truck has 251K on it. Non vvt not mds. Just the way I like it.
I feel with you, with my 06 Charger R/T Daytona with 138.000mls/230.000km on it.. i got it to improove the relia/durability to gt a true long-,hopefully life long running car! ;) I did made many little modifications to improove that. Like an 15 Row Oil Radiator, 0W40 Motor Oil (ESTER Based + ESTER Ceramic Additives), shut down MDS, 93 Oct Tune(diablo), 180°F/93°C Thrmostat (for both; Water & Motoroil) & some more of that stuff. the lower opperating tmp with the higher temp motor oil grade is a good thing i think, nice greetings from Bavaria (ger)
@@tillivanilli6481 I have an 06 charger RT R&T I'm about to hit 193k Miles. Its my daily.
@@zacharygalliher609 NICE! :) I think you should hold that car, maintain & repair it when something is bad or damaged & run it again :) Esp. the ´06 - ´08 / 1st Gen of the Chargers are the greatest of the modern aera Chargers & i thhink that these would go to be true modern classics in some years....or what do you think??? I also think that the "R/T´s" are not less importand than the SRT models of these to keep alive & not to trash them. they´re one of the most importand kind of Chargers/Chrysler/Dodge Models ever produced with the 300C. They not only safed Chrysler/Dodge, they was the only true way of making a new introduction of the great american sedan & Dodges/Chryslers with the styling, design + th V8/HEMI´s + RWD. & if this company would be successful in future, these kind of features are the most importand to keep.
@@tillivanilli6481 oh yeah I'm keeping it. Especially considering dodge is getting rid of the hemi engines and replacing it with a tt inline 6. Mines been in a few wrecks and had botched paint repairs. But I want to have it repainted at some point. The 06 R/T R&T is kinda rare. Its essentially a Daytona package without the cosmetics. So it comes with the SRT seats, SRT air intake, slightly better suspension. Only approximately 6600 we're made to that spec. It's not worth anymore but most people don't know they exist.
My junk yard sells engines by number of cylinders not what it is. V-8 short blocks run under $200 and a core drops it more.
Hemi's are gone the second they hit the ground.
do a 392 intake, and ported 6.1 heads, and choose a better cam for the pre-eagle block, and 1.875 or 2" primary long tube headers. should be really close to 520-550hp.
But I own a 2018 Dodge Challenger SRT Hellcat that gives me all I want. And I can't hook-up on most city streets at 707HP.
Ok.... So .... Drop the eagle heads on the Carbie hemi? Don't care if the late model would be cheaper; if someone already had the 1st gen of the 3rd gen, with a carb, etc., And those heads- with the right valve train and cam, would it be more better?
I drive a 2007 hemi ram single cab short with heads, injectors, throttle body, upper and lower intake cold air it's so fun too drive!!i can beat stock r/ts, run down 5.o's and ss camaros, and barely lose 2 scat packs! Theres alot there with the 5.7, theres a kit 2 put a hellcat supercharger on the earlier 3rd gen and the eagle. I wish they would keep that motor line up.if dodge goes all electric I will be crushed!!!
400 for the engine and 800 for an srt heads and you are all ready better than the expensive eagle heads .
@@turbojetpowered8299 tell actually way better and you only need a ticker gasket. Ask me how I know. 2 you can also fit a 6.1 crankshaft as well whit out having to cut the block.
@@turbojetpowered8299 man if you are afraid of a tesla then it tell me that you didn't build by your self any of your engines . Any AWD with a decent engine build and a tune will send him to dust, telsa have speed limits and loose power at top speed. Try to drive any tesla at 90 mph consistently for 3 hours and see what happens.
@@turbojetpowered8299 dude a daily drive an scape titanium AWD 2.0 . Is fun but not that fun.
The 2007 hemi does not have a carburetor so I don’t know where you’re getting that from but OK
The one they have in the video does, so don’t know where you’re getting that from but OK 😂
I would get an Eagle engine and put boost to it. Hellion twin turbo or cheaper supercharger kit.
Eagle also comes with a 70,000-80,000 mile CLCI (Cam and Lifter Change Interval)!
I'm glad they did this test. For me I have an '05 Hemi in a '67 Dart post. Converting it over to carburetor was more expensive for me. I wanted the motor but I wanted it to look like a classic motor. That's why I converted over to carb. The difference is I bought a throttle body fuel injector with fuel rails so it's not really a carbureted engine. Obviously you lose a lot of horsepower going this route as proven by this video above. I have a small cam in it to make enough HP power for me to spin the wheels and sound the part. It's not a world beater but it's a ton of fun.
I have an '05 Ram 1500 standard cab with 3.92 rear / hemi. It goes pretty good and roasts the tires pretty well, too. One thing that I think is being left out here is that the earlier motor with a stock or small cam is better down low, like for towing and cruising, especially with a 5 speed trans, which trucks do. They're railing on the early motor, but I think a little unfairly.
I would buy a Sniper EFI kit and you would have the fuel injection reliability you're after and it would look stock with the air cleaner esp.
I wonder what engine oil viscosity they are running in those engines. I know the oil brand. Its sponsored by AMSoil.
No 318 going touch 5.7l Hemi from 2005 dodge magnum RT lmfao - FACTS
Did I miss something? That eagle hemi is running almost 50hp and 50lb/ft more than factory claimed. The the "car" eagle hemi was rated at 360-375 crank hp and 375-390 lb/ft. The truck was 380-395 crank hp and 407-410 lb/ft. The pre eagle hemi in the LX cars was rated 345-350 crank hp and 390 lb/ft of torque. So, a peak difference of 25 hp and equal torque between the two "car" engines. These numbers seem to be on par with a lightly modded pre eagle hemi and theirs, but the numbers on the eagle hemi look way inflated unless those are some incredible headers they have on there. From my personal experience, my L92 Escalade ESV absolutely embarresses my wife's 2012 5.7 JGC in acceleration. And, I also have a lightly modded (LMI intake, suitcase delete, hemifever 93 tune, 180° t-stat) 07 300c AWD that has repetitively pulled ever so slightly on my buddies 2013 AWD 300c with just a muffler delete. There is a negligible difference, as the new cars got heavier. But, I can't see 440 crank hp on a "stock" 5.7. That's more than the 6.1 ever made.
You need HP tuners to 🔓 unlock the other 75. It's hidden in the cam and power request tables
We need the freiburger super Bee 484ci hemi engine on engine masters pleasee
In the 03 to 08 year model blocks, what casting is the best 53 or 58 block?
You’ll make more power from a 5.7 then a 6.2 or 6.4 facksssss
New to do a compression vid...I believe compression don't make horses power facts
389 hp is awesome,better then a 1970 440 cid.@375 hp😊
Could someone please stop giving Steve chicklets gum... it's affecting his teeth
Miller David Walker Matthew Robinson Jessica
I wonder if a duel carb with a better cam make a difference against the fuel injection
Didn't hear your talk bout valve Train issues on the later model.??
They're not mentioning the cost of a stand alone for the efi. Would love to see a carbed 6.4.
And with either Tri-power or dual quads!
I had a 2005 Chrysler 300c early build 07/2004 (I'm talking 16x2 foot long(+-😆) sparkplug wires). @ 120k, I wanted to have some fun, I called up Inertia Motor Sports and put together a plan on a super budget! Purchased a used Eagle intake manifold had my 5.7 heads hand ported to match the eagle intake manifold milled 40 over, a Super Spartan (something something 🤷🏾♂️non-mds) this was NOT a rebuild , same 120k rods, pistons,rings, crank NOTHING else! At that time (2011-ish) I was told she had the record for highest HP cam only 5.7 Hemi
@ 404rwhp? and she was a lot of fun!!
I also had an even earlier build 2005 Magnum R/T (05/2004 build) maybe something about those "SPAGHETTI" wires draped over the manifold 😆 (UGLY engine compartment very basic full exhaust, cai and a hand held box tune and she was fast too for want it was.
This 3rd Gen Hemi is only a marketing ploy. . If you want a real Hemi you have to go to the experts. FHO being my choice.
Or Arruzza if you can get him on the phone, FHO is my top choice also.
Who is FHO?
To current? Not any more. Bye bye v8. Hemi is dead.
Stroking is always compatible correct?
Long tubes, a cam and most importantly, port and polish the exhaust ports as much as possible, and you get massive power out of a 5.7 HEMI. Easily in the 500 - 520hp range. The entire engine is so perfecf for making horsepower... except the exhaust tract. The intake flow numbers are insane. The port angles are perfect. The intake valves are nice and big... but then they put a somewhat small exhaust valves, with a tight exhaust port, a stock cam with not enough exhaust lift or duration, and absolute garbage exhaust manifolds.
It's clear too me Chrysler wanted the 5.7 held back for a reason, and I get it. If it had even half decent exhauat manifolds and more appropriate exhaust ports, the 5.7 would turn out an easy 410hp with nothing else. When they upgrades rhe 5.7 in 2009, the 6.1 was making 425hp for $10,000 more. They handicapped the 5.7 because they knew they would never sell the 6.1 for $10,000 more, kf the 5.7 was making only 15 less hp for $10,000 less. That's my theory.
Compare it to a 318 or 360 .... still much better
You guys are the best for sure, Fryberg is the OG of guru's Love It!!!!
