Unfortunately, if you look at similarly sized LS motors they tend to make more power but only with a cylinder head swap. Hemi vs LS using stock head, Hemi could win. But with aftermarket heads and valves, LS tends to win. Maybe because there isn't much choice on Hemi heads for some reason, and aftermarket LS heads have a much more aggressive design than the stock Hemi head?
@@sepg5084 that's not true. You can find heads or just have the shop port them. Gm motors won't come close to a built Mopar now. Maybe true 25yrs ago but not now. If you take a 345ci hemi, stock out of a truck, you can go find 6.1 or 392 heads and they bolt right on. That's not where the power is though. The cheapest hp is to find a wrecked 6.1l srt motor and bolt on the intake manifold. Gm is crap anymore and Ford is chasing the government around kissing their ass for money.
There's more on the table from there. My 6.4L crate motor with the stock intake, cylinder head porting and cam put out 615.2 HP @ 6700RPM - 553.2 Lb-Ft @ 4600RPM. The stock intake with the SRV system is surprisingly good vs switching to an aftermarket with single length runners.

Why do I feel like it should make more than that? Something feels like it's "off" on this combo...like not enough cam to take advantage of the intake or something. I dunno, but a SBM (LA or Magnum) can be built to both more power and definitely more torque.
Yea that's what I was thinking, +70 hp over my stock scat for all that work doesn't seem like a lot. I've seen similar builds to this push that magical 600 HP mark before forced air, so something is being held back here. Then again, it is fully built so this engine could easily take on a FI kit and easily crank out above hellcat numbers, so the potential is there at least.
my 94 dakota has almost 250,000 miles on its 5.2 magnum v8 which is showing signs of its age.. it'd be a great home for this hemi, if I had the money I'd be building me one just like it instead of dreaming bout it cuz thers no way I could afford it right now
@@bigboreracing356 not sure,Anyway I got Lucy enough to work on a promos making 3500 hp but I thought this looks cool also the Godzilla 7.3 gas has nice numbers as well.
When you’re dealing with 6.4L’s and you want to add some power adders. Remember to widen the ring gap. Because it will be the weak point for higher horsepower. And remember that gen3 hemi’s lifter issue is from a lack of splash lubrication. So try to keep it above 2,000Rpm.
It's the raised cam location they mentioned puts them to far out of windage...and they are laid way over....non mds with hemi lifters seem to be a cure..... I'll say this on my 2021 ram its impossible to keep it over 2000...it only turns about 1800 at 80mph hehe
Oil pressure is too low at the rocker assembly at idle with the engine hot. Splash lube is irrelevant here. The lifters are oiled from the rocker assembly and the oil is pushed down the pushrod. Hellcat oil pump is the fix. Works awesome. Much thicker rotor and idle oil pressure is a lot better.
@@sHoRtBuSseR Hellcat oil pump without the oil squirters the hellcat has, would be raising oil pressure too much and start causing other issues. Melling has an updated oil pump design with a higher volume and a bit more psi to help with lubrication while keeping everything within safe parameters.
@@bigboreracing356 Bcs they used shit lifters from factory you assume the whole engine is shit ? Great logic there ...you must be one of those internet basement engineers I keep hearing about !
can tell you from automotive experience we never used duralast. I can guarantee they don't check what they send out had to return so many duralast parts helped a friend went through 8 duralast alternators before one worked and the alternator was in a pain spot. After each return the staff acted as if it was normal never use anything duralast there cheaply done and quality control dosnt exist. Every shop I've been in its Napa or oriellys that's what the real pros use this was nothing but paid advertising no good pro uses duralast and if they do they've just been lucky.
Great video! I would've loved to see the combustion chamber and for y'all to explain quench and how it can still be a hemi with one. Much love for the Mopar vids y'all do!
Great questions it’s got some serious perks by having the quench area. Makes the camber smaller while still having the valves placed in the optimal position for size and flow. Also raises the compression. The piston doesn’t have to have as much of dome shape to fill the chamber which allows the piston to be lighter. Duel plugs for aid in cleaner and more efficient burn. 340 CFM of flow from a stock head wow!! This engine was for the most part stock. Just a buffed up Valvetrain/cam/intake/rods/piston. 7000rpm 🙌🏼 I wish they took it higher, looked like it was still making power!!
@@alexwowski5318 they didn't balance the rotating assembly as a whole, after doing drop in pistons and rods they'd be asking for problems going that fast without making sure everything checks out even though they used good quality parts.
Longer stroke would be the guarantee for more TQ. Also running a tighter lobe separation angle around 108deg would have increased TQ and probably HP. We seen to be stuck in an era of really wide LSA and then try to compensate with more duration. Giving the engine what it wants has been forgotten.
You could also use it to clearance stroke but the problem seems that's what causes the premature lifter failures.....raised to far out of windage and the lifters not vertical enough... I keep waiting for this to happen on my Ram....I know MDS exacerbates this but oh well... Having built several LS it literally is an LS with Hemi heads hehe....nice design
Would love to put a 6.4 in my 2005 ram 1500 with a 4.7 has 190k miles but it’s not hard miles and I live in southern Ohio and the trucks been here it’s whole life but it’s rear wheel drive so we never drive it in the winter and well no rust at all but I’d love to slap a 6.4 in there with a built transmission and a Holley terminator
That’s a great looking engine and a good video but for all the upgrades it seems a little disappointing, the SRT 6.4L is rated at 485 hp and 475 lb/ft tq, they barely produced any more torque over factory at all, good bump in horsepower though. I’d still like to see a NA 6.4 making big torque numbers like 600+ surely if they could do it 50 years ago with carburetors there’s no reason they can’t today!
my son has a 2007 Jeep Grand Cherokee 5.7 with 186 000 k on it and I am afraid the engineis going to blow up I would love too surprise him with this life time watcher
I've heard of problems with Hemi tick, the cam and lifters being under lubed and wearing. Has Chrysler addressed that? Did you do any thing to address it? With all the Hemi owners and lovers commenting here I don't think the "problem" is as big as some make it seem elswhere.
Surely they didn't do all that building up for a reman Duralast that'll be done for after their break in and dyno runs. I know that was just sponsor chit chat. Soon as that camera left, they went with a Mopar, Melling, Meizere, Milodon or even a Mishimoto lol
I came here for the dad jokes and horsepower, I was not let down. But yet again y'all locked out the cam phasing on us. It's 2021, it's time to show the world what a little on the fly cam timing can do to these engines, guys! MERICA!

Yea that's what I was thinking, +70 hp over my stock scat for all that work doesn't seem like a lot. I've seen similar builds to this push that magical 600 HP mark before forced air, so something is being held back here. Then again, it is fully built so this engine could easily take on a FI kit and easily crank out above hellcat numbers, so the potential is there at least.
my 94 dakota has almost 250,000 miles on its 5.2 magnum v8 which is showing signs of its age.. it'd be a great home for this hemi, if I had the money I'd be building me one just like it instead of dreaming bout it cuz thers no way I could afford it right now
Stock pistons wont take hardly any abuse. 6psi and you are on the edge already.
Just seen a small block 427 Hemi ford making 900 hp on air !
Lookup hammerhead 427
@@bigboreracing356 all natural, no nitrous or blower.
@@bigboreracing356 lookup hammerhead ford I think
@@bigboreracing356 not sure,Anyway I got Lucy enough to work on a promos making 3500 hp but I thought this looks cool also the Godzilla 7.3 gas has nice numbers as well.
@@bigboreracing356 there was hope for the 6 litre cammer ,but more support for the 7.3.
Arrington is probably the best place for anything HEMI. I’d kill for one of their forged engines in my Charger
When you’re dealing with 6.4L’s and you want to add some power adders. Remember to widen the ring gap. Because it will be the weak point for higher horsepower. And remember that gen3 hemi’s lifter issue is from a lack of splash lubrication. So try to keep it above 2,000Rpm.
It's the raised cam location they mentioned puts them to far out of windage...and they are laid way over....non mds with hemi lifters seem to be a cure.....
I'll say this on my 2021 ram its impossible to keep it over 2000...it only turns about 1800 at 80mph hehe
Oil pressure is too low at the rocker assembly at idle with the engine hot. Splash lube is irrelevant here. The lifters are oiled from the rocker assembly and the oil is pushed down the pushrod. Hellcat oil pump is the fix. Works awesome. Much thicker rotor and idle oil pressure is a lot better.
@@sHoRtBuSseR Hellcat oil pump without the oil squirters the hellcat has, would be raising oil pressure too much and start causing other issues. Melling has an updated oil pump design with a higher volume and a bit more psi to help with lubrication while keeping everything within safe parameters.
@@bigboreracing356 Bcs they used shit lifters from factory you assume the whole engine is shit ? Great logic there ...you must be one of those internet basement engineers I keep hearing about !
I liked in less than 30 seconds...Plum Crazy and black did it for me.
Everything but the super charger, could you list all the parts used in the 6.4 and what block, 6.4 gen 3?
That engine will be awesome in my 1977 w200
Rival the LS?! Haha haha that's a good joke!
can tell you from automotive experience we never used duralast. I can guarantee they don't check what they send out had to return so many duralast parts helped a friend went through 8 duralast alternators before one worked and the alternator was in a pain spot. After each return the staff acted as if it was normal never use anything duralast there cheaply done and quality control dosnt exist. Every shop I've been in its Napa or oriellys that's what the real pros use this was nothing but paid advertising no good pro uses duralast and if they do they've just been lucky.
Great video! I would've loved to see the combustion chamber and for y'all to explain quench and how it can still be a hemi with one. Much love for the Mopar vids y'all do!
Great questions it’s got some serious perks by having the quench area. Makes the camber smaller while still having the valves placed in the optimal position for size and flow. Also raises the compression. The piston doesn’t have to have as much of dome shape to fill the chamber which allows the piston to be lighter. Duel plugs for aid in cleaner and more efficient burn. 340 CFM of flow from a stock head wow!! This engine was for the most part stock. Just a buffed up Valvetrain/cam/intake/rods/piston. 7000rpm 🙌🏼 I wish they took it higher, looked like it was still making power!!
@@alexwowski5318 they didn't balance the rotating assembly as a whole, after doing drop in pistons and rods they'd be asking for problems going that fast without making sure everything checks out even though they used good quality parts.
I was hoping for more torque than just 4 lb ft over stock for having new pistons, rods, cam, and that massive intake on it. Hp looked good though.
Longer stroke would be the guarantee for more TQ. Also running a tighter lobe separation angle around 108deg would have increased TQ and probably HP. We seen to be stuck in an era of really wide LSA and then try to compensate with more duration. Giving the engine what it wants has been forgotten.
This would be great for my 66 dodge charger. It was my dad's old car I tracked down. Its rough but I'm doing a tribute to him. Would love this
My dad had a 69 440
Just to top post, that raised camshaft is to shorten the pushrods to lower valvetrain mass.
You could also use it to clearance stroke but the problem seems that's what causes the premature lifter failures.....raised to far out of windage and the lifters not vertical enough...
I keep waiting for this to happen on my Ram....I know MDS exacerbates this but oh well...
Having built several LS it literally is an LS with Hemi heads hehe....nice design
thank you for all the free content
My 2023 Durango SRT 392 runs so nice, so smooth. Claimed 475 hp and torque... is it true? Does the stock motor really make those numbers?
This is a great engine, and purple is our school's color. I want to put one of these in my 99 Durango.
Would love to put a 6.4 in my 2005 ram 1500 with a 4.7 has 190k miles but it’s not hard miles and I live in southern Ohio and the trucks been here it’s whole life but it’s rear wheel drive so we never drive it in the winter and well no rust at all but I’d love to slap a 6.4 in there with a built transmission and a Holley terminator
My 5.7 hemi could use such a sweet swap 😎
That a great motor
Could you do that with a gen4 6.4 and install that in a 2016 Dodge ram 1500 to get rid of the 5.7 what would it take
Wow what a build! Mopar FTW🔥
My 08 Dakota sport would make a nice sleeper truck w that magnificent beast of an engine in it.
A GREAT BUILD FOR ANY DAILY DRIVER.
What’s your outlook on the lifter problems and the valve seat problem with the 2020 and newer 5.7 Hemi?
They fixed the valve seat issue in like 09
Has stupid ring setting tool, and bolt stretch tool, but holds camshaft by stuffing screwdriver in the end 6:35 🤔
It's amazing how a thousandth or a 10 thousandth can change everything
One badass motor foresure!
I'd really like to have this done to my 5.7
Would l9ve to see some 6.4L Gen 3 truck hemi builds.
That’s a great looking engine and a good video but for all the upgrades it seems a little disappointing, the SRT 6.4L is rated at 485 hp and 475 lb/ft tq, they barely produced any more torque over factory at all, good bump in horsepower though. I’d still like to see a NA 6.4 making big torque numbers like 600+ surely if they could do it 50 years ago with carburetors there’s no reason they can’t today!
Those were 8L engines not 6.4's with those HP numbers...
Hello pat. Great show. I see Mike isn’t there. Will he be back? Thank you.
I need this for my jeep srt . I'll definitely be entering.
my son has a 2007 Jeep Grand Cherokee 5.7 with 186 000 k on it and I am afraid the engineis going to blow up I would love too surprise him with this life time watcher
Yup, like to plant that into my Scat Pack!! Interesting video!!
my dad suv aka charger truck aka durango would love this as much as the kids would 🤣💯👑🙌🏿💨
I've heard of problems with Hemi tick, the cam and lifters being under lubed and wearing. Has Chrysler addressed that? Did you do any thing to address it? With all the Hemi owners and lovers commenting here I don't think the "problem" is as big as some make it seem elswhere.
where i can get the ARP bolts that they use in all the engine components?
Surely they didn't do all that building up for a reman Duralast that'll be done for after their break in and dyno runs. I know that was just sponsor chit chat. Soon as that camera left, they went with a Mopar, Melling, Meizere, Milodon or even a Mishimoto lol
I hope that HEMI will fit in my Caravan! LOL!
lovely build! did not you do pcv system?
Man id love to build one and you guys make it look not difficult
I would love to put it in my '16 Ram Bighorn. That things a beast.
Compair the Holley High Ram to the Edelbrock Victor 2?
Holy cow.... That's quite a good motor getting good.But them dudes got toops.
Would you guys be able to build my 6.4L Charger scat so I can super or pro charger it and it still be reliable and won’t blow up
Do you get less valve float with a conical spring vs. straight valve spring?
Don't you wish people actually answered great questions like yours lol?
Love the video. Thanks. I blew my engine in my 392 and need another built. How do I order a built 392??
Love me that 6.4 HEMI, Yessir…
😫 pat don't like 4 cylinder I'm fan got a little toyota with 22r was hoping he can eventually do one still a bad ass pat
I came here for the dad jokes and horsepower, I was not let down. But yet again y'all locked out the cam phasing on us. It's 2021, it's time to show the world what a little on the fly cam timing can do to these engines, guys! MERICA!
I got a 2010 Dodge ram 1500 with a 3.7l . this would be my dream upgrade.
